Description

Catheter and manufacturing method thereof < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a catheter, and more particularly, to a medical catheter for treating a disease, particularly, a nerve blocking catheter for allowing nerve conduction to be inactivated by ablating a part of the nerve, .

Neural blockade is a procedure in which a part of the nerve pathway is blocked so that stimulation or information is not transmitted to the nerve such as the sensory nerve or autonomic nerve. Such neural blockade is becoming increasingly used for the treatment of various diseases including arrhythmia, pain relief, and molding.

Particularly, recently, it has been confirmed that such neural blockade is effective for the treatment of hypertension, and efforts to apply such neural blockade as a method for effectively treating hypertension have been attempted.

In the case of hypertension, since most of the blood pressure can be controlled as a drug, many hypertension patients are currently being treated for hypertension depending on the drug. However, such a method of lowering blood pressure by drugs has various problems such as inconvenience of continuous drug taking, cost aspect, and side effects such as organ damage due to prolonged use of the drug. In addition, some hypertensive patients suffer from refractory hypertension that is not controlled by blood pressure as a drug. Such refractory hypertension is not treated as a drug, and therefore, there is a great risk of causing an accident such as stroke, arrhythmia, kidney disease, etc., and treatment of intractable hypertension is a serious and urgent problem.

In this situation, neural blockade has attracted attention as a breakthrough method for treating hypertension. In particular, neural blockade for treating hypertension can be accomplished in such a way that the neural conduction is deactivated by ablating the sympathetic nerve around the kidney, i. E. Activation of the kidneys increases renal hormone production by the kidneys, which can lead to elevated blood pressure. Therefore, it has recently been shown through various experiments that hypertension can be treated, as nerve conduction can not be achieved by blocking these kidney nerves.

As such, a typical method of blocking the kidney nerve for the treatment of hypertension is to use a catheter. Neuroprotection using a catheter is a technique in which a catheter is inserted into a part of the body, such as a thigh, and the distal end of the catheter is placed in the renal artery along the blood vessel. Thereby blocking the sympathetic nerve around the renal artery.

These catheter-based neuroblastomas are much smaller than neural blockade through open surgery, which can greatly reduce the potential complications and side effects, and the advantages of partial anesthesia treatment and recovery time are very short, Is attracting attention as a treatment for hypertension.

However, the catheter-related technology for applying to the neural blockade and the like has not yet been sufficiently developed, and has many parts to be improved.

In particular, the catheter must be small enough to be able to move freely along the interior of the blood vessel, so that its size should be very small. However, in the case of the prior art, there are many difficulties in downsizing such a catheter.

Furthermore, in the head portion of the catheter developed or proposed in the past, there are provided at least one electrode and various devices for sensing, and various wires for transmitting power or electrical signals to the electrodes and the sensing device are also included. Therefore, it is very difficult to manufacture a catheter having both of these and a small size in the case of the prior art.

In addition, since the catheter, particularly the head portion of the catheter positioned at the most distal end, must be small in size, the various structures that enter it are also inevitably small in size and it is not easy to handle such a fine structure.

Therefore, manufacturing a catheter head using such fine structures in the past requires complicated processes, high precision, and high reproducibility, so that the catheter quality and manufacturing yield are lowered and the safety and stability of the catheter is poor It can cause problems.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a perspective view schematically showing a head configuration of a catheter according to an embodiment of the present invention, and FIG. 2 is an exploded view of the configuration of FIG. 1. More specifically, Fig. 2 is a view showing a state in which the portion A in Fig. 1 is separated and expanded in the B1 and B2 directions. 3 is a right side view of the configuration of Fig. 1. Fig. In FIGS. 1 and 2, for the sake of convenience of explanation, the configuration of a part that is not visible at the time of observation is indicated by a dotted line.

Here, the head of the catheter refers to the end of the longitudinally opposite end of the catheter extending in one direction to reach the treatment site, and is referred to as a catheter tip or a distal end It is possible. And, such a catheter may have a proximal end located at the operator side than the distal end, as opposed to the head of the catheter. Hereinafter, for the various constituent elements included in the catheter extending in the longitudinal direction of the catheter and having both ends, the end portion located on the head side, i.e., the distal end side of the catheter, is referred to as a distal end And the end located on the proximal end side of the catheter is referred to as the proximal end.

1 to 3, a catheter according to the present invention may include a cylinder member 100, an electrode 200, and a power supply wiring 300.

The cylinder member 100 is formed in the shape of a pipe or tube extending in one direction and has a hollow space V formed therein along the longitudinal direction. The hollow V may be configured to expose at least one end along the longitudinal direction of the cylinder member 100. For example, in the configuration of FIG. 1, the cylinder member 100 may be configured such that both the left end and the right end of the hollow V are open.

On the other hand, in the configuration of Fig. 1, the left side end of the cylinder member 100 is a proximal side end, and the right side end is a distal side end leading to the treatment site. Thus, the ratio of the length in the left-right direction and the length in the up-and-down direction of the cylinder member 100 shown in FIG. 1 is merely an example. Therefore, the ratio of the length of the cylinder member 100 in the left-right direction and the length in the up-down direction can be variously configured.

The cylinder member 100 may be formed in various shapes depending on a part or purpose to be used, and may have various sizes such as an inner diameter and an outer diameter. In addition, the cylinder member 100 may have various materials, and may be configured to have electrical insulation as a whole for forming the power supply wiring 300.

The electrode 200 is mounted on the cylinder member 100 and can generate heat by receiving power. In this way, the heat generated by the electrode 200 can ablate surrounding tissue. For example, the electrode 200 generates heat of about 40 ° C or higher, preferably 40 ° C to 80 ° C, so that the nerve around the blood vessel can be removed, thereby blocking the nerve. However, it goes without saying that the temperature of the heat generated by the electrode 200 can be variously changed according to the purpose or purpose of the catheter.

Since the electrode 200 can apply heat to the nerve tissue located in the vicinity of the blood vessel in contact with the blood vessel wall, it is preferable that the electrode 200 comes in close contact with the blood vessel wall. Therefore, the electrode 200 may be formed in a curved shape, such as a circular, semicircular or elliptical shape, so as to correspond to the shape of the inner wall of the blood vessel. According to this embodiment, since the adhesion of the electrode 200 to the blood vessel wall can be improved and contact with the inner wall of the blood vessel can be maximized, the heat generated by the electrode 200 can be transmitted to the nerve tissue around the blood vessel . In addition, when the electrode 200 is formed in a curved shape, the inner wall of the blood vessel can be prevented from being damaged by the electrode 200.

The electrode 200 may be made of a material such as platinum or stainless steel. However, the present invention is not limited to the specific material of the electrode 200, and various factors such as a heat generation method, It can be composed of various materials.

Preferably, the electrode 200 may generate heat in a radio frequency (RF) manner. For example, the electrode 200 may be electrically connected to the high-frequency generating unit to dissipate high-frequency energy to excise the nerve.

Meanwhile, the electrode 200 existing in the catheter can act as a cathode. The anode corresponding to the cathode can be connected to an energy supply unit such as a high frequency generating unit like a cathode, Lt; / RTI >

In the catheter according to the present invention, one or more of the electrodes 200 may be included. In particular, as shown in the drawing, the electrode 200 may be mounted on the cylinder member 100 in plurality. According to this embodiment of the present invention, the plurality of electrodes 200 can further increase the blocking rate for the nerves located around the blood vessel.

Particularly, in the catheter according to the present invention, the power supply wiring 300 is printed on the cylinder member 100. For example, the power supply wiring 300 may be provided in the cylinder member 100 in such a manner as to leave a conductor as a two-dimensional pattern on one surface of the cylinder member 100, as shown in Figs. . The power supply wiring 300 may be configured such that it is exposed to the outside from the surface of the cylinder member 100. However, the present invention is not limited thereto, and the power supply wiring 300 may be formed in such a manner as to be embedded in the cylinder member 100 It is possible.

The power supply wiring 300 may be partially connected to the electrode 200 to provide a power supply path for supplying power to the electrode 200. For example, as shown in Figs. 1 and 2, the power supply wiring 300 may be printed in an elongated form extending from one side (left side) to the other side (right side) to function as an electric circuit, When power is supplied at one end, this power source can be flowed along the power supply wiring line 300 and supplied to the electrode 200. Particularly, one end of the power supply wiring 300 is connected to the high frequency generating unit so that the energy generated by the high frequency generating unit is transferred to the electrode 200, so that heat generation by the high frequency energy in the electrode 200 .

1, the power supply wiring 300 is printed on the inner wall surface of the cylinder member 100. However, the present invention is not necessarily limited to these embodiments. For example, the power supply wiring 300 may be printed on the outer wall surface of the cylinder member 100.

As described above, in the case of the catheter according to the present invention, since the power supply wiring line 300 is printed on the cylinder member 100 itself, according to this configuration of the present invention, It is not necessary to separately provide an electric wire for supplying power. Thus, the size, particularly the diameter, of the head portion of the catheter can be reduced, making it easier to achieve miniaturization of the catheter. According to the present invention, the electrode 200 can be mounted on the power supply wiring 300 and the process of inserting the electrode 200 into the hollow V of the cylinder member 100, It is possible to simplify the manufacturing process of the catheter and increase the reproducibility, thereby improving the safety and stability of the catheter.

In addition, in the case of the catheter according to the present invention, the electrode 200 may be mounted on the cylinder member 100 in a printed form on the cylinder member 100. For example, the electrode 200 may be mounted on the cylinder member 100 such that a material capable of forming an electrode is printed on one surface of the cylinder member 100. According to this embodiment of the present invention, the structure of the catheter is simplified, miniaturization is easy, and the process can be simplified.

Preferably, the cylinder member 100 may be configured such that two sides extending from one end to the other end of the hollow V along the longitudinal direction of the hollow V are coupled and fixed.

For example, as shown in FIG. 1, when the hollow V is extended from the left end to the right end of the cylinder member 100, at one side of the cylinder member 100, May be provided along the longitudinal direction (lateral direction) of the hollow V.

These engaging portions may be portions where other mutually spaced apart sides of the cylinder member 100 are fastened to each other. Accordingly, when the engagement of the portion A is released and the cylinder member 100 is extended to the portions indicated by the arrows B1 and B2, the cylinder member 100 can be configured in a wide plate shape as shown in FIG.

2, the cylinder member 100 has a structure in which a large plate-shaped member on which the electrodes 200 are mounted and the pattern of the power supply wiring lines 300 is printed, 2 are fastened and fixed to each other to form a hollow as shown in FIG. To this end, the two variables A1 and A2, which are coupled to each other, are bent by being bent in the directions as indicated by the arrows C1 and C2, and can be fastened and fixed in mutual contact.

Here, the two sides to be coupled to each other may be fixedly engaged with each other, or a part of the surfaces may be fixedly coupled with each other. Alternatively, the two sides joined to each other may not be in contact with each other but may be engaged and fixed in an adjacent state.

According to this configuration of the present invention, mounting of the electrode 200 and printing of the power supply wiring 300 can be facilitated. That is, as shown in FIG. 2, the cylinder member 100 according to the present invention is formed in a plate shape, and a plurality of mutually spaced apart sides are fixed by bending, Printing of the mounting and / or power supply wiring 300 can be performed in the case of a plate form. Thus, such mounting and / or printing processes can be easily performed.

Preferably, the cylinder member 100 may be formed in a cylindrical shape, as shown in FIG.

According to this configuration of the present invention, the process of bending the cylinder member 100 in a plate form can be made easier. That is, in order to form the cylindrical cylinder member 100, the bending process as shown by C1 and C2 in FIG. 2 can be performed in a curved shape at one time, and it is not necessary to make a separate edge, Formation can be made easier.

Also, preferably, the cylinder member 100 can be engaged and fixed to the two sides in such a manner that the projection is inserted into the insertion groove. For example, in the configuration of FIG. 2, protrusions may be formed on the upper side A1 of the plate-shaped cylinder member 100, and grooves may be formed on the lower side A2. The plate-shaped cylinder member 100 is curved in a circular shape in the directions of the arrows C1 and C2 so that A1 and A2 adjoin each other and then the projection of A1 is inserted into the insertion groove of A2, Can be maintained.

Here, such an inserting method can be realized by a hook fixing method. For example, the protrusion of A1 is formed in the form of a hook, and such protrusion can be hooked to the insertion groove of A2.

However, the manner of fixing the engaging portions to the two sides of the cylinder member 100 is not necessarily limited to this embodiment, and may be embodied in various forms. For example, in the cylinder member 100, the two sides may be engaged and fixed by an adhesive. That is, when the plate cylinder member 100 as shown in Fig. 2 is bent in the C1 and C2 directions so that the two sides A1 and A2 meet each other, an adhesive is applied to at least one side, Can be intervened. Therefore, in this case, the bonding state of A1 and A2 can be maintained through such an adhesive.

As described above, in the case of the catheter according to the present invention, particularly the catheter head located on the distal end side of the catheter, the plate-shaped cylinder member 100 is formed in a tube shape by being bent and joined. Therefore, the cylinder member 100 may be made of a flexible material having insulation properties. For example, the cylinder member 100 may be made of a soft material such as rubber or plastic.

Meanwhile, the catheter according to the present invention may be provided with a plurality of electrodes 200. In this case, the at least two electrodes 200 may be spaced a predetermined distance in the longitudinal direction of the cylinder member 100. For example, as indicated by d1 and d2 in FIG. 2, the plurality of electrodes 200 may be spaced a predetermined distance from each other in the lengthwise direction of the cylinder member 100, that is, the longitudinal direction of the catheter.

According to this embodiment of the present invention, it is possible to prevent the stenosis from being caused due to the ablation by the plurality of electrodes 200. That is, when the heat is radiated from the plurality of electrodes 200, a phenomenon may occur in which the heated portion of the blood vessel swells in the direction of the blood vessel. If the distance between the electrodes 200 in the longitudinal direction of the blood vessel is short, Can occur. However, according to this embodiment of the present invention, since the plurality of electrodes 200 are spaced apart from each other by a predetermined distance in the longitudinal direction of the catheter, the heating portion of the blood vessel may be formed to be spaced a predetermined distance along the longitudinal direction of the blood vessel . Therefore, according to this configuration of the present invention, it is possible to prevent stenosis from occurring at the site even if heat is applied to cut the nerve around the blood vessel.

Here, the distances d1 and d2 between the electrodes 200 may be variously configured depending on the size of the catheter, the operation site, and the like. For example, the catheter may be configured such that the distance between the electrodes 200 in the longitudinal direction of the cylinder member 100 (left-right direction in FIG. 1) is 0.3 cm to 0.8 cm. In this embodiment, it is possible to prevent the stenosis of the blood vessel and to minimize the problem that the nerve around the blood vessel passes between the electrodes 200, and the nerve ablation by the electrode 200 is not performed.

Also, preferably, the two or more electrodes 200 may be configured to be spaced apart from each other by a predetermined angle relative to the center axis of the cylinder member 100.

For example, as shown in FIG. 3, the angles formed by the line segments connecting the respective electrodes 200 from the central point O, which is the central axis of the cylinder member 100 and the central axis of the hollow, are g1, g2, and g3 G1, g2, and g3 have angles greater than 0 DEG, and the angles between the three electrodes 200 may be different from each other. For example, g1, g2, and g3 may all be equally configured to be 120 degrees.

According to the embodiment in which the electrode 200 is spaced at a predetermined angle between the electrodes 200 with respect to the central axis O of the cylinder member 100, . Therefore, the electrode 200 can be configured so as not to miss such a nerve even if the nerve is disposed at any part of the blood vessel.

FIG. 4 is a perspective view schematically showing the configuration of a catheter head according to another embodiment of the present invention, and FIG. 5 is an exploded view of the configuration of FIG. More specifically, FIG. 5 is a view of the form in which the portions D and E of FIG. 4 are separated and expanded. 6 is a cross-sectional view taken along line F1-F1 'of FIG. 4 to 6 will not be described in detail with respect to portions in which the description of the configurations of Figs. 1 to 3 can be similarly applied, and the differences will be mainly described.

4 to 6, the catheter has the electrode 200 mounted on the cylinder member 100 and connected to the electrode 200 in the same manner as the configuration shown in Figs. 1 to 3, The power supply wiring line 300 can be printed on the power supply line 100.

1 to 3, the cylinder member 100 may include a first cylinder 110, a second cylinder 120, and a connecting member 130.

The first cylinder 110 is formed in the shape of a cylinder having a hollow (V), and the power supply wiring 300 can be printed from one end to the other end. For example, in the configurations of Figs. 4 and 5, the first cylinder 110 may be printed with the power supply wiring 300 from the left end to the right end.

The second cylinder 120 may be formed to be coaxial with the first cylinder 110 and spaced apart from the first cylinder 110 by a predetermined distance in the longitudinal direction of the hollow cylinder. 4 and 5, the second cylinder 120 is located on the right side of the first cylinder 110, that is, on the distal side, and is disposed in a form spaced apart from the first cylinder 110 by a predetermined distance .

The connecting member 130 is interposed between the first cylinder 110 and the second cylinder 120, which are spaced apart from each other by a predetermined distance. That is, the connecting member 130 may be configured such that one end thereof is connected to the first cylinder 110, and the other end thereof is connected to the second cylinder 120. 4 and 5, the connecting member 130 may be configured such that its left end is connected to the first cylinder 110 and its right end is connected to the second cylinder 120. [

The connecting member 130 may be integrated with the first cylinder 110 and / or the second cylinder 120. In this case, the connecting member 130 may be formed by cutting a wide plate-shaped material into a shape as shown in FIG. According to this embodiment of the present invention, the first cylinder 110, the second cylinder 120, and the connecting member 130 can all be provided from one base plate, and the connecting member 130 and the first cylinder 110 and between the connecting member 130 and the second cylinder 120 may not be necessary. Therefore, the manufacturing process of the cylinder member 100 can be simplified and the structure can be prevented from becoming complicated.

Alternatively, the connecting member 130 may be implemented separately from the first cylinder 110 and / or the second cylinder 120. In this case, the connection member 130 may be made of a material or a material different from that of the first cylinder 110 and / or the second cylinder 120. In this case, in this case, the connecting member 130 may be formed in a variety of shapes, such as using a first cylinder 110 and / or a second cylinder 120 and a fastening member such as a projection, a screw, . ≪ / RTI >

The electrode 200 may be mounted on the surface of the connecting member 130. In particular, the electrode 200 may be mounted on the outer surface of the connecting member 130. Here, the outer surface means the side surface located outside the cylinder member 100, not the inner surface forming the hollow of the cylinder member 100. Thus, when the electrode 200 is positioned on the outer surface of the connecting member 130, the electrode 200 may be located closer to the inner wall of the blood vessel.

The connection member 130 can be printed with the power supply wiring 300. Particularly, the power supply wiring 300 of the connection member 130 may be formed from one end of the connection member 130 to a portion where the electrode 200 is mounted. For example, referring to FIGS. 4 and 5, the power supply wiring 300 may extend from the left end of the connection member 130 to a portion where the electrode 200 is connected.

Here, the power supply wiring 300 printed on the connection member 130 is configured to be connected to the power supply wiring 300 of the first cylinder 110. 4 and 5, the left end of the power supply wiring 300 printed on the connecting member 130 is connected to the right end of the power supply wiring 300 printed on the first cylinder 110, Respectively. The power supplied from one end of the first cylinder 110 is supplied to the electrode 200 via the power supply wiring 300 of the first cylinder 110 and the power supply wiring 300 of the connection member 130 Lt; / RTI >

Although the power supply wiring 300 is printed only up to the point where the electrode 200 is mounted, the present invention is not necessarily limited to this embodiment. For example, in the configurations of FIGS. 4 and 5, the power supply wiring 300 may extend from the electrode 200 to the second cylinder 120.

Meanwhile, the first cylinder 110 and the second cylinder 120 may be provided with engaging portions along the longitudinal direction of each hollow, as indicated by D and E in Fig. That is, in the first cylinder 110, the two sides D1 and D2, which are spaced apart from each other by a predetermined distance, are adjacent to each other by bending of the cylinder member 100 and fixed to each other, have. The second cylinder 120 has two sides E1 and E2 which are spaced apart from each other by a predetermined distance and are adjacent to each other due to bending of the cylinder member 100 and fixed to each other, have.

Preferably, the connecting member 130 may be configured such that at least a portion thereof is bent when the distance between the first cylinder 110 and the second cylinder 120 is narrowed, so that the bending portion is away from the hollow . This will be described in more detail with reference to Figs. 7 and 8. Fig.

FIG. 7 is a view schematically showing a configuration in which the connecting member 130 is bent in the configuration shown in FIG. 4, and FIG. 8 is a sectional view taken along the line F2-F2 'in FIG.

4, when the distance between the first cylinder 110 and the second cylinder 120 becomes close to each other, the distance between both ends of the connecting member 130 becomes close to each other, 7, at least a portion can be bent.

The bending portion of the connecting member 130 may be configured to move away from the hollow. Here, the bending portion is a portion bent at the vertex of the bent portion, that is, the bent portion of the connecting member 130 most severely or the bent portion of the connecting member 130 from the central axis of the cylinder member 100 It can be said that it means the part located farthest. Further, the fact that the bending portion is away from the hollow means that the bending direction of the bending portion is formed in the outward direction of the cylinder member 100, so that the bending portion is away from the center axis O of the hollow.

The connecting member 130 may be made of a flexible material so that a bending portion can be formed as the distance between the first cylinder 110 and the second cylinder 120 is narrowed.

In addition, according to one embodiment of the present invention, the connecting member 130 may be formed from a single flexible substrate together with the first cylinder 110 and the second cylinder 120, The member 130 may also be bendable.

However, the present invention is not necessarily limited to such an embodiment, and the connecting member 130 may be made of a material different from that of the first cylinder 110 and the second cylinder 120. [ For example, the connecting member 130 can be more flexibly bent than the first cylinder 110 and the second cylinder 120, so that the connecting member 130 is more flexible than the first and second cylinders 110 and 120, For example, it can be made of a material with better elongation.

6, the connecting member 130 has a cross section in a direction perpendicular to the longitudinal direction, similar to the first cylinder 110 and the second cylinder 120, And may be formed in a bent shape with respect to the center axis O of the hollow. Accordingly, when the distance between both ends is close, the connecting member 130 can be bent in a direction in which the bending portion is away from the central axis O of the hollow, as indicated by arrows I1, I2 and I3 in Fig.

The electrode 200 may be provided at a bending portion of the connecting member 130. At this time, it is preferable that the electrode 200 is provided at a portion farthest from the central axis of the hollow among the bending portions of the connecting member 130. That is, when the first cylinder 110 and the second cylinder 120 are brought close to each other and the bending portion is formed on the connecting member 130, the electrode 200 is positioned at the vertex of the bending portion located farthest from the hollow central axis .

According to this embodiment, while the catheter head is moving to the treatment site, it moves in the form as shown in Fig. 4, and when the catheter head reaches the treatment site, as shown in Fig. 7, ) Can be bent. Then, by making the electrode 200 protrude from the cylinder member 100 as much as possible, the electrode 200 can be made closer to the blood vessel wall. In addition, since the electrode 200 can be prevented from protruding during movement, movement of the catheter head can be made more smooth, and damage of the blood vessel wall by the connecting member 130, the electrode 200, and the like can be prevented.

Preferably, the cylinder member 100 may include a plurality of connecting members 130, as shown in FIGS. In this case, the electrode 200 may be mounted on two or more different connecting members 130, respectively.

For example, as shown in FIGS. 4 to 8, the cylinder member 100 may include three connecting members 130. Each of the three connecting members 130 may be provided with an electrode 200. At this time, in order to supply power to the three electrodes 200, the power supply wiring 300 may be separately printed on each of the three connecting members 130. In correspondence with the three power supply wiring 300, , The first cylinder 110 may also be printed with three power supply lines 300.

As described above, according to the embodiment in which a plurality of connecting members 130 are provided and a plurality of electrodes 200 are provided, the nerve blockage rate around the blood vessel can be further increased.

In such a configuration, the two or more connecting members 130 may be configured such that the mounting points of the electrodes 200 are spaced a predetermined distance in the longitudinal direction of the hollow. In this case, the electrodes 200 may be spaced a predetermined distance from each other in the longitudinal direction of the hollow, that is, the longitudinal direction of the catheter. Therefore, according to this embodiment of the present invention, the nerve block rate can be further increased while preventing stenosis due to the plurality of electrodes 200 as described in the embodiments of FIGS. 1 to 3 above.

Also, in this configuration, the two or more connecting members 130 may be configured to be spaced apart from each other by a predetermined angle relative to the central longitudinal axis of the hollow. For example, as shown in FIGS. 4 and 6, the connecting member 130 may be configured to be radially offset, such as 120 degrees, relative to the central axis of the hollow. According to this embodiment of the present invention, as described in the embodiments of FIGS. 1 to 3, the effect of preventing the stenosis and the nerve blocking effect due to the plurality of electrodes 200 can be further enhanced.

FIG. 9 is a perspective view schematically showing a configuration of a catheter head according to another embodiment of the present invention, and FIG. 10 is an exploded view of the configuration of FIG. More specifically, Fig. 10 can be said to be a figure in which J and K portions of Fig. 9 are separated and expanded. 9 and Fig. 10 will not be described in detail with respect to portions in which the description of the configurations of the foregoing Figs. 1 to 8 can be similarly applied, and the differences will be mainly described.

9 to 10, the cylinder member 100 may include a first cylinder 110, a second cylinder 120, and a plurality of connecting members 130. The first cylinder 110 and the second cylinder 120 may have joint portions such as J and K, respectively.

9 to 10, the two or more connecting members 130 may be configured such that a connecting point with the first cylinder 110 and / or the second cylinder 120 is spaced a predetermined distance in the longitudinal direction of the hollow have.

10, when the three connecting members 130 are provided in the cylinder member 100, each connecting member 130 is connected to the first cylinder 110 at the left side The end portions may be configured to be spaced apart from each other by a distance of L1 and L2. 10, each connecting member 130 may be configured such that the right end, which is the point at which it is connected to the second cylinder 120, is spaced a predetermined distance from each other by L3 and L4 distances.

At least one of the first cylinder 110 and the second cylinder 120 may be formed in the first cylinder 110 and / or the second cylinder 120 so that the connecting point between the connecting member 130 and the first cylinder 110 and / 9 and 10, a step may be formed on the side surface to which the connecting member 130 is connected. For example, when three connecting members 130 are connected to the right side surface of the first cylinder 110, three stages may be formed on the right side surface of the first cylinder 110, . Also, the left surface of the second cylinder 120 to which the three connecting members 130 are connected may be formed with three steps having a step in the left-right direction.

When the connecting point of the connecting member 130 with respect to the first cylinder 110 and / or the second cylinder 120 is spaced a predetermined distance in the longitudinal direction of the hollow as described above, the first cylinder 110 and the second cylinder 120, The bending portions may be spaced apart from each other by a predetermined distance when the connecting member 130 is bent. That is, when both ends of the connecting member 130 are bent to be bent, the bending portion is likely to be formed mainly at the center of the connecting member 130. According to the embodiment of the present invention, since the central portion of the connecting member 130 may be spaced apart from each other by a predetermined distance in the longitudinal direction of the catheter, the bending portions of the connecting members 130 may be spaced apart from each other by a predetermined distance . Therefore, if the electrode 200 is mounted on the central portion of each connecting member 130, a configuration in which the electrodes 200 are spaced apart from each other by a predetermined distance can be easily achieved when the connecting member 130 is bent have.

9 and 10, the connecting points of the connecting member 130 are configured to be spaced apart from each other by a predetermined distance through a configuration in which a step is formed in the first cylinder 110 and the second cylinder 120 , But the present invention is not necessarily limited to these embodiments.

As another example, by providing the inclined surface on the side surface of the first cylinder 110 and / or the second cylinder 120 to which the connecting member 130 is connected, Distance can be made.

In addition, in the catheter according to the present invention, the configuration for separating the connection points of the connection member 130 with respect to the first cylinder 110 and the second cylinder 120 may be implemented in various ways.

Preferably, the catheter according to the present invention may further include a temperature sensing member 410 and a temperature sensing wiring 420, as shown in Figs. 9 and 10.

The temperature sensing member 410 is a component for measuring the ambient temperature. For example, the temperature sensing member 410 may be a thermocouple. In particular, such a temperature sensing member 410 may be mounted around the electrode 200. [

According to this embodiment of the present invention, since the ambient temperature can be measured through the temperature sensing member 410, whether the heat emitted from the electrode 200 is a temperature suitable for excising the nerve tissue around the blood vessel, It can be confirmed whether it is low or not.

In particular, in the case of the catheter head according to an embodiment of the present invention, the connecting member 130 is provided with the electrode 200, and the connecting member 130 is bent in a direction away from the center axis of the catheter head Can be bent. Accordingly, the temperature sensing member 410 is provided on the connection member 130 in the same manner as the electrode 200, so that the amount of heat by the electrode 200 can be more accurately measured.

Further, when a plurality of connecting members 130 are provided, a plurality of such temperature sensing members may be provided and mounted on different connecting members 130.

The temperature sensing wiring 420 may be two-dimensionally printed on the cylinder member 100 in the same manner as a circuit pattern, similarly to the power supply wiring 300. 9 and 10, in a case where the cylinder member 100 includes the first cylinder 110, the second cylinder 120, and the connecting member, the temperature sensing wiring 420 may be formed, for example, May extend from the left end to the right end of the first cylinder 110 and extend from the left end of the connecting member 130 to the point where the temperature sensing member 410 is mounted. The temperature sensing wiring 420 may be formed separately from the power supply wiring 300 without being electrically connected thereto.

The temperature sensing wiring 420 may be connected to the temperature sensing member 410 to provide a path for transmitting temperature information sensed by the temperature sensing member 410. For example, if the temperature sensing element 410 is implemented as a thermocouple, the current generated in the thermocouple may be delivered to an external temperature measurement device connected to the catheter via the temperature sensing wiring 420.

Preferably, the catheter according to the present invention may further include a tactile sensing member and a tactile sensing wiring 520, as shown in Figs. 9 and 10.

The tactile sensing member 510 is a component for measuring tactile information. The tactile sensing member 510 may be mounted inside or around the electrode 200. In this case, the tactile sensing member 510 can be checked whether the electrode 200 is in contact with the blood vessel wall.

According to this embodiment of the present invention, when it is confirmed through the tactile sensing member 510 that the electrode 200 is touching the blood vessel wall, power is supplied to the electrode 200, . In addition, the distance between the first cylinder 110 and the second cylinder 120 can be controlled by the information through the tactile sense member 510. For example, according to one embodiment of the present invention, when the distance between the first cylinder 110 and the second cylinder 120 approaches, the bending of the connecting member 130 causes the electrode 200 to be in contact with the blood vessel The distance between the first cylinder 110 and the second cylinder 120 can be narrowed until it is confirmed by the tactile sensing member 510 that the electrode 200 is touching the blood vessel wall.

9 and 10, the tactile sensing member 510 is mounted on the periphery of the electrode 200. However, the tactile sensing member 510 may be mounted inside the electrode 200 . In this case, the tactile sensing member 510 can provide more accurate information as to whether the electrode 200 has contacted the blood vessel wall.

The tactile sensing wiring 520 may be printed two-dimensionally on the cylinder member 100 in the same manner as the circuit pattern, similarly to the power supply wiring 300. [ 9 and 10, when the cylinder member 100 includes the first cylinder 110, the second cylinder 120, and the connecting member 130, the tactile sensing wiring 520 May extend from the left end to the right end of the first cylinder 110 and extend from the left end of the connecting member 130 to the point where the tactile sensing member 510 is mounted .

The tactile sensing wiring 520 may be connected to the tactile sensing member 510 to provide a path for transmitting the tactile sense information sensed by the tactile sensing member 510.

The tactile sensing wires 520 may be formed separately from each other without being electrically connected to the power supply wires 300. When the temperature sensing wiring 420 is formed on the cylinder member 100, the tactile sensing wiring 520 may be formed separately from the temperature sensing wiring 420. In this case, as shown in Figs. 9 and 10, a total of three wires, that is, the power supply wiring 300, the temperature sensing wiring 420 and the tactile sensing wiring 520, are connected to one connecting member 130 . 9 and 10, when a total of three connecting members 130 are present in the cylinder member 100, a total of nine wiring lines may be provided.

FIG. 11 is an exploded perspective view schematically showing the configuration of a catheter according to another embodiment of the present invention, and FIG. 12 is a perspective view of the configuration of FIG. 13 is a cross-sectional view taken along the line M-M 'in Fig.

11 to 13, the catheter according to the present invention includes the cylinder member 100, the electrode 200, and the power supply wiring 300, which are included in the catheter head 1000, It can be positioned at the most distal side. The catheter according to the present invention may further comprise a shaft body 2000 as a component that engages the proximal end of such a catheter head 1000.

The shaft body 2000 is coupled to the proximal end side of the cylinder member 100, and this coupling structure can be achieved in various ways. For example, as shown in Fig. 11, the distal side end portion of the shaft body 2000 may be configured to be insertable into the hollow of the cylinder member 100. [ Alternatively, the combination of the catheter head and the shaft body may be implemented in such a manner that the proximal side end of the catheter head is inserted into the distal side end of the shaft body.

In particular, the shaft body 2000 may have a connection terminal 2100 on the distal end side so as to be able to engage with various wirings provided in the catheter head when coupled with the catheter head.

11 to 13, the power supply wiring 300, the temperature sensing wiring 420 and / or the tactile sensing wiring 520 are printed on the inner surface of the cylinder member 100 of the catheter head, for example, . The shaft body 2000 has a power supply terminal 2110 connected to the power supply wiring 300 and a temperature sensing terminal 2120 connected to the temperature sensing wiring 420 and / Or a tactile sensing terminal 2130 connected to the tactile sensing wiring 520.

The terminal of such a shaft body may be embodied in various ways, such as being printed on the surface of the shaft body similar to the catheter head, or formed by inserting a small metal plate into the hole of the shaft body.

Here, the terminal provided on the shaft body to be connected to the wiring of the catheter head may be formed to be elongated in the coupling direction of the catheter head and the shaft body. 11, the power supply terminal 2110, the temperature sensing terminal 2120, and / or the tactile sensing terminal 2130 of the shaft body may be elongated in the left-right direction, for example, . According to this embodiment of the present invention, when the catheter head and the shaft body are coupled, the power supply wiring 300, the temperature sensing wiring 420 and / or the tactile sensing wiring 520 of the catheter head slides in this coupling direction So that the contact force between the terminal of the shaft body and the wiring of the catheter head can be further improved when the terminals of the shaft body are elongated in this coupling direction.

Also, for this reason, the power supply wiring 300, the temperature sensing wiring 420, and / or the tactile sensing wiring 520 of the catheter head may be formed to be elongated in the coupling direction of the catheter head and the shaft body .

Preferably, at least one of the catheter head and the shaft body may be provided with a coupling guide portion P so as to guide mutual coupling directions. For example, as shown in Figs. 11 and 13, a projection P1 is formed at the distal end of the shaft body, and at the proximal end of the catheter head in a position and shape corresponding to the projection P1, (P2) may be formed.

According to this embodiment of the invention, when engaging between the catheter head and the shaft body, the engaging direction can be guided. In particular, one or more wires are formed in the catheter head, and one or more terminals are formed in the shaft body such that when the catheter head and the shaft body are engaged, these wires and terminals must be interconnected. Therefore, according to the above-described embodiment, the coupling direction is guided by the coupling guide portion P, so that the coupling between the wires of the catheter head and the terminals of the shaft body can be easily and accurately performed.

In addition, the catheter head may be provided with various types of wiring such as a power supply wiring 300, a temperature sensing wiring 420, and a tactile sensing wiring 520. In this case, various types of terminals are formed in the shaft body Thus, it is necessary to connect the terminals of the same type of wiring. Therefore, according to the configuration in which the coupling guide portion P exists as in the above-described embodiment, such coupling can be accurately performed.

Meanwhile, although not shown in the drawings, the catheter according to the present invention may further include a cover at a distal side end portion. That is, in the above drawings, the distal end of the cylinder member 100 is formed with a hollow opening, but the distal end of the hollow may be configured to be closed by the cover.

The cover may be integrally formed with the cylinder member 100. For example, in an exploded view as shown in FIG. 2, a circular cover may be configured to exist integrally with the cylinder member 100 at the right end of the cylinder member 100. In this case, the cylinder member 100 is bent in a circular shape in the directions of C1 and C2 in Fig. 2, and the circular cover can be engaged with the cylinder member 100 to seal the hollow at the right end of the cylinder member 100 have.

Alternatively, the cover may be configured separately from the cylinder member 100, and may be coupled to the distal-side end of the cylinder member 100 in a state where the cylinder member 100 is bent in a circular shape.

14 is a perspective view schematically showing a configuration of a catheter according to another embodiment of the present invention. With respect to the configuration shown in FIG. 14, a description of the configuration in which the configuration of FIG. 1 to FIG. 13 can be similarly applied will not be described in detail, and differences will be mainly described.

14, a catheter according to the present invention may further include an end tip 600 at a distal end of the catheter, i. E., A distal end of the catheter head.

The end tip 600 may be formed of a soft and flexible material. In particular, the end tip 600 may be formed of a composition comprising a polyether block amide (PEBA). Here, the composition forming the end tip 600 may include other additives besides polyether block amide. For example, the end tip 600 may be formed of a composition comprising 70% polyether block amide and 30% barium sulfate as a total weight percent composition.

According to this configuration of the present invention, when the distal end portion of the catheter moves along the blood vessel or the like, the end tip 600 made of a soft and flexible material is located at the frontmost position, so that damage to blood vessels and the like can be reduced, . Further, in the case of the end tip 600 made of the above-described material, since the X-ray can be taken, the position of the catheter head can be easily grasped.

Preferably, the end tip 600 may be configured in the form of a tube having a hollow. The hollow of the end tip 600 may be formed to extend in the same direction as the longitudinal direction of the catheter. As such, when the end tip 600 is formed in the form of a tube, the guide wire may pass through the hollow of the end tip 600. For example, the end tip 600 may have a length of 6 mm and be configured as a tube having a hollow diameter of 0.7 mm.

The end tip 600 may be elongated along the extension direction of the catheter. At this time, the end tip 600 may be formed to have a different size along the length direction thereof. In particular, when the end tip 600 is formed into a cylindrical shape, the diameter of the distal end portion may be smaller than the other portion. For example, when the diameter of the thickest portion is 1.3 mm, the diameter of the distal end may be 1.1 mm, which is the thinnest.

The end tip 600 preferably has an appropriate length that is not excessively long or short. For example, the length of the end tip 600 may be 5 mm to 15 mm in the lateral direction of Fig. According to this configuration of the present invention, disturbance to movement due to the end tip 600 can be reduced in moving along the inner space of the blood vessel or the inner space of the sheath. According to this configuration of the present invention, the degree and direction of the warp of the end tip 600 can be grasped and the shape of the blood vessel can be easily grasped at the portion where the end tip 600 is positioned.

15 is a flow chart schematically illustrating a method of manufacturing a catheter according to an embodiment of the present invention.

15, a method of manufacturing a catheter according to the present invention includes steps of preparing a cylinder member S110, a power supply wiring printing step S120, an electrode mounting step S130, a cylinder member 100 bending step S140, And a joint fixing step (S150).

The cylinder member preparation step S110 is a step of preparing the plate-shaped cylinder member 100 as shown in Figs. 2, 5 and 10. Fig. As described above, the cylinder member 100 may be a planar configuration spreading two-dimensionally widely.

The power supply wiring printing step (S120) is a step of printing the power supply wiring 300 on the cylinder member 100. [ For example, in step S120, the power supply wiring 300 is printed (printed) in such a manner as to leave a conductor as a two-dimensional pattern on one surface of the cylinder member 100, as shown in FIGS. 2, 5, can do.

The electrode mounting step (S130) is a step of mounting one or more electrodes on the cylinder member (100). In particular, in step S130, the electrode may be mounted to be connected to the power supply wiring line 300 of the cylinder member 100.

In addition, the step S130 may be performed by printing an electrically conductive material for forming an electrode on the cylinder member.

The bending step (S140) of the cylinder member 100 is a step of bending the cylinder member 100 to form a cylinder having a hollow shape. For example, in step S140, the plate-shaped cylinder member 100 is bent as indicated by C1 and C2 in FIG. 2 so that the cylinder member 100 is shaped like a cylinder as shown in FIG. 1 . The step S140 may be a configuration for three-dimensionally changing the two-dimensional configuration.

In step S140, the plate-shaped cylinder member 100 may be bent so that two spaced apart portions of the cylinder member 100 are adjacent to each other. For example, the step S140 may bend the plate-shaped cylinder member 100 so that the upper side A1 and the lower side A2 are adjacent to each other, as shown in FIG.

In the coupling and fixing step S150, the other sides of the adjacent cylinder members 100 are coupled and fixed by bending. For example, in step S150, the portion A is coupled and fixed in the configuration shown in FIG. 1, so that the tube shape as shown in FIG. 1 can be maintained as it is.

Here, in step S150, the protrusions provided on one side of the two sides of the cylinder member 100 adjacent to each other by bending are inserted into the insertion grooves provided on the other side so that the two sides are engaged and fixed can do.

Alternatively, in step S150, two sides of the cylinder member 100 adjacent to each other by bending may be bonded by an adhesive so that two sides of the cylinder member 100 are engaged and fixed.

Meanwhile, in step S150, the fixing force may be entirely received from one end of the hollow to the other end, or only a part of the hollow may receive the fixing force.

The cylinder member preparation step S110 may include a cylinder member 100 having a first cylinder 110, a second cylinder 120 spaced apart from the first cylinder 110 by a predetermined distance, (130) connected to the first cylinder (110) and the other end connected to the second cylinder (120).

For example, in the step S110, a cylinder member 100 in the form of a plate like the structure shown in Fig. 5 can be prepared. 5, the plate-shaped first cylinder 110 may be the first base plate, and the plate-shaped second cylinder 120 may be the second base plate. The plate-shaped connecting member 130 may be referred to as a connecting plate.

Also, the power supply wiring printing step (S120) may print the power supply wiring 300 from one end of the first cylinder 110 to a point where the electrodes of the connection member 130 are mounted. For example, as shown in FIGS. 5 and 10, in step S120, the power supply wiring is extended in the left-right direction from the left end of the first cylinder 110 to the point where the electrode is mounted, It is possible to print.

In the cylinder member preparation step S110, the cylinder member 100 may include a plurality of connecting members 130, and the electrode attaching step S130 may include connecting the electrodes to two or more different connecting members 130, 130, respectively. For example, in step S110, a cylinder member 100 having three connecting members 130 is prepared, and in step S130, three connecting members 130 are connected to electrodes Can be mounted.

Also, it is preferable that the electrode mounting step (S130) be such that the electrodes mounted on the two or more connecting members 130 are spaced a predetermined distance in the longitudinal direction of the hollow formed in the bending step S140. For example, as shown in FIGS. 5 and 10, in step S130, the plurality of electrodes may be mounted on the connecting member 130 at a predetermined distance in the left-right direction.

The cylinder member preparation step S110 may be performed by bending at least one of the first cylinder 110 and the second cylinder 120 at a portion where the connecting member 130 is connected in a bending step S140 A step or a slope may be formed in the longitudinal direction of the hollow. For example, in the step S110, a cylinder member may be prepared in the form as shown in FIG.
