Description

  The present invention relates to a balloon catheter set.

  For example, in percutaneous transluminal angioplasty (PTA) and percutaneous transluminal coronary angioplasty (PTCA), a balloon catheter having an expandable / deflatable balloon is used. The balloon catheter is stored in a bag body in an unused state and packaged as a medical device set (see, for example, Patent Document 1).

  In the medical device set described in Patent Document 1, for example, an information pamphlet to which the pressure value of the working fluid supplied to the balloon is attached is attached to the balloon catheter as an accessory. In this state, the information pamphlet is stored in the bag together with the balloon catheter.

  However, in the medical device set described in Patent Literature 1, when collecting balloon catheters and information brochures and packing them in a bag, the information brochures may be forgotten to be difficult for the balloon catheter or forgotten to be put in the bag. There was a problem that there was. Further, even when the information brochure is stored in the bag in advance, there is a problem that the information brochure may be lost when the medical device set is used. In addition, when using the medical device set, even if the information brochure was dropped on the floor and picked up and used, there was a problem in terms of hygiene. These problems are all due to the existence of information brochures.

  Hereinafter, the balloon catheter set of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

<First Embodiment>
FIG. 1 is a plan view showing a first embodiment of the balloon catheter set of the present invention. FIG. 9 is a plan view of a balloon catheter provided in the balloon catheter set shown in FIG. In the following, for convenience of explanation, the left side in FIG. 9 is referred to as “base end” and the right side is referred to as “tip”.

  A balloon catheter set 10 shown in FIG. 1 is used for, for example, percutaneous transluminal angioplasty (PTA) or percutaneous transluminal coronary angioplasty (PTCA). And a storage structure 1 for storing 20. Hereinafter, the configuration of each unit will be described. In addition, it is preferable that the balloon catheter set 10 is hermetically stored in, for example, a bag body in an unused state. Thereby, the aseptic condition of the balloon catheter set 10 can be maintained until the bag is opened.

  As shown in FIG. 9, the balloon catheter 20 includes a long catheter body 201, a hub 202 provided at the proximal end of the catheter body 201, a balloon 203 provided at the distal end of the catheter body 201, a balloon And a stent 204 that is detachably attached to the outer periphery of 203.

  The catheter body 201 is composed of a flexible tube, and has a lumen 205 through which the working fluid supplied to the balloon 203 flows down.

  The total length of the catheter body 201 is not particularly limited, and is appropriately determined according to the use site or case of the balloon catheter 20, but is usually preferably about 1000 to 2000 mm. In addition, the outer diameter (average outer diameter) of the catheter body 201 is preferably about 0.2 to 3 mm, and more preferably about 0.3 to 2 mm.

  The hub 202 is composed of a hard cylindrical member and communicates with the lumen 205 of the catheter body 201. The working fluid can be introduced into the lumen 205 through the hub 202.

  The balloon 203 is composed of a tubular membrane member and is fixed to the distal end portion of the catheter body 201. The lumen 205 communicates with the balloon 203. The balloon 203 is in a state of being collapsed and folded before expansion (when deflated), but is expanded by supplying a working fluid therein.

  The stent 204 is a cylindrical member made of, for example, a metal mesh, and is attached to the outer peripheral portion of the folded balloon 203 in a contracted state in which the outer diameter and the inner diameter contract. When the balloon 203 is expanded from this state, the stent 204 is forcibly deployed from the inside by the balloon 203, that is, the outer diameter and the inner diameter are expanded. The expanded stent 204 can secure the inner diameter in the blood vessel.

  As shown in FIG. 1, the storage structure 1 includes a catheter storage body 2 and a plurality of (four in the illustrated configuration) holding members (clips) 3.

  The catheter housing 2 is composed of a flexible long tube (tubing body) 21, and the catheter body 201 of the balloon catheter 20 is housed (inserted) together with the stent 204 in the hollow portion 211. The tube 21 is open (opened) at both ends, and the balloon catheter 20 can be inserted and removed from one opening 212 side.

  The tube 21 has a total length that can sufficiently accommodate the catheter body 201, and the total length is preferably 100% or more and 110% or less of the total length of the catheter body 201, 102 % Or more and 105% or less is more preferable. The inner diameter of the tube 21 is preferably 150% or more and 350% or less, and more preferably 200% or more and 300% or less, of the outer diameter of the contracted stent 204 attached to the balloon 203. The outer diameter of the tube 21 is preferably 125% or more and 145% or less of the inner diameter of the tube 21, and more preferably 130% or more and 140% or less.

  The catheter housing 2 is obtained by winding a tube 21 in a spiral shape (loop shape). Accordingly, the hollow portion 211 also has a shape that is spirally wound. Moreover, when the tube 21 forms a spiral shape, one opening 212 is positioned outside the spiral, and the other opening 213 on the opposite side is positioned inside the spiral. And since one opening part 212 is located in the outer side of a spiral, the insertion / extraction operation of the balloon catheter 20 with respect to the one opening part 212 can be performed easily.

  In addition, as a constituent material of the catheter housing 2 (tube 21), it is preferable to use a material harder than the catheter body 201, and examples thereof include polyolefin.

  The color of the catheter housing 2 is not particularly limited, but an opaque white color is preferable. Thereby, the visibility of the information 4 attached to the catheter housing 2 as described later is improved.

  Four holding members 3 that hold (maintain) the loop state of the tube 21 shown in FIG. 1 are installed in the catheter housing 2. These holding members 3 are installed at intervals along the winding direction of the tube 21.

  Each holding member 3 is composed of a plate piece, and three grooves 31 are formed on one surface thereof in parallel with each other. The tubes 21 can be fitted in the respective grooves 31. Thereby, the loop state of the tube 21 can be reliably held, that is, the positional relationship between the three adjacent tubes 21 aligned in the radial direction of the loop can be maintained. Therefore, for example, while the balloon catheter 20 is being removed from the tube 21, it is possible to prevent the loop state of the tube 21 from being unfolded (split) and making the removal operation difficult. After the balloon catheter 20 is removed, the catheter housing 2 is discarded without removing the holding member 3. Hereinafter, the portion where the three tubes 21 are arranged is referred to as a “tubular juxtaposed portion 22”.

  As shown in FIG. 1, information 4 is directly attached to the outer periphery of the tube 21. This information 4 is information related to the balloon catheter 20, and in this embodiment, there are three types of items.

  The first item 41 includes a plurality of (six in the configuration shown in FIG. 1) inner diameter values 41a, 41b, 41c, 41d, 41e, and 41f indicating the degree of deployment of the stent 204, and the item name 41g. The item name 41g is “stent inner diameter”.

  The second item 42 includes pressure values 42a, 42b, 42c, 42d, 42e, 42f of a plurality of (six in the configuration shown in FIG. 1) working fluid according to the degree of deployment of the stent 204, and a unit 42g thereof. is there. The unit 42g is “atm”.

  The third item 43 includes pressure values 43a, 43b, 43c, 43d, 43e, 43f of a plurality of working fluids (six in the configuration shown in FIG. 1) depending on the degree of deployment of the stent 204, and a unit 43g thereof. is there. The unit 43g is “kPa”. The second item 42 and the third item 43 are equivalent.

  And the 1st item 41-the 3rd item 43 are attached | subjected to the tubular body juxtaposition part 22 of the tube 21, and the 1st item 41, the 2nd item 42, and the 3rd item 43 in order from the outer side. Is arranged. The first item 41 to the third item 43 do not overlap any holding member 3, that is, are not hidden by the holding member 3.

  In the first item 41, the inner diameter values 41a to 41f are arranged along the winding direction of the tube 21, that is, the longitudinal direction in order of increasing value, with the item name 41g as the head, and thereafter at intervals. . In the second item 42, the pressure values 42 a to 42 f are arranged along the winding direction of the tube 21 in order from the smallest value, with the unit 42 g as the head, and thereafter being spaced apart. Similarly, in the third item 43, the pressure values 43a to 43f are arranged along the winding direction of the tube 21 in order of increasing values, with the unit 43g as the head, and thereafter being spaced apart.

  In the first item 41 to the third item 43 arranged as described above, the inner diameter value 41a of the first item 41, the pressure value 42a of the second item 42, and the pressure value 43a of the third item 43 are as follows. It corresponds. The distal end of the tube 21 from the winding center (central portion) 23 has an inner diameter value 41a, a pressure value 42a adjacent to the inner diameter value 41a, and a pressure value 42a adjacent to the innermost value 23a. There is a value 43a. This positional relationship includes a set of corresponding inner diameter value 41b, pressure value 42b and pressure value 43b, a set of inner diameter value 41c, pressure value 42c and pressure value 43c, and a set of inner diameter value 41d, pressure value 42d and pressure value 43d. The same applies to the set of the inner diameter value 41e, the pressure value 42e, and the pressure value 43e, and the set of the inner diameter value 41f, the pressure value 42f, and the pressure value 43f.

  In addition, as a method of using the information 4, the inner diameter of the stent 204 in the expanded state (hereinafter referred to as “indicated inner diameter”) is attached to the bag body by printing or the like. Are selected from the inner diameter values 41a to 41f. Then, the pressure value corresponding to the selected inner diameter value is selected from the pressure values 42a to 42f or the pressure values 43a to 43f. For example, when the indicated inner diameter is “2.89”, the inner diameter value 41a is viewed, and the corresponding pressure value 42a or pressure value 43a is confirmed. When supplying the working fluid to the balloon 203, the supply is performed at "7 atm (or 709 kPa)". Thus, the arrangement of the first item 41 to the third item 43 is an arrangement that is easy to see when used.

  Moreover, in the balloon catheter set 10, since the information 4 is directly attached to the catheter housing 2, the balloon catheter is set more than when the information 4 is attached to a member different from the catheter housing 2 such as a sheet body. The number of parts constituting the set 10 can be reduced. The sheet body with the information 4 is generally referred to as “compliance sheet”.

  And the reduction of this compliance sheet | seat also makes it possible to reduce the manufacturing cost of the balloon catheter set 10. In addition, it is possible to eliminate forgetting to put the compliance sheet into the bag body, which has conventionally occurred. Even if the compliance sheet is previously stored in the bag, for example, the compliance sheet may be lost during surgery. However, according to the balloon catheter set 10, this loss can also be prevented.

  As described above, the loop state of the tube 21 is held by each holding member 3. Thereby, the positional relationship between the corresponding stent inner diameter and the pressure value is also maintained, so that the working fluid can be supplied to the balloon 203 at an accurate pressure value when the stent 204 is expanded.

  Moreover, in the balloon catheter set 10, the item of information 4 can be increased / decreased according to the number of times the tube 21 is wound.

  The method for attaching the information 4 to the outer periphery of the tube 21 is not particularly limited, and for example, it is preferable to use a method of irradiating the outer periphery of the tube 21 with laser light. Thereby, the information 4 can be attached easily and reliably, and the attached information 4 can be prevented from peeling off. In addition to this, the method for attaching the information 4 includes, for example, a printing method by applying ink.

Second Embodiment
FIG. 2 is a plan view showing a second embodiment of the balloon catheter set of the present invention.

  As shown in FIG. 2, in the present embodiment, a fourth item 44 as information 4 is further added to the tubular body juxtaposed portion 22 of the catheter housing 2. The fourth item 44 is “CATTHETER SET” which is the name of the present invention. Each alphabet constitutes one alphabet across the radial direction of the loop in the tubular body juxtaposed portion 22.

  For example, when an unintentional force acts on the catheter housing 2 from the state shown in FIG. 2, the positional relationship between the tubes 21 adjacent to each other may be shifted in the tubular body juxtaposed portion 22. In this case, in the first item 41 to the third item 43, the corresponding stent inner diameter and pressure value are shifted, which is not preferable in reading the information 4.

  Even in the fourth item 44, each alphabet is not in an accurate display state, but if the positional relationship between the tubes 21 is returned so that it is in an accurate display state, the corresponding stent inner diameter and pressure value 2 is restored to the state shown in FIG. As a result, the first item 41 to the third item 43 can be accurately read.

  As described above, in the balloon catheter set 10 of the present embodiment, the fourth item 44 has a function as a “positional deviation recognition marker” that allows the user to recognize a positional deviation between the tubes 21. Can do.

  The fourth item 44 is the general name of the product in the present embodiment, but is not limited to this. For example, the name of the manufacturer of the balloon catheter set 10, the name of the seller, a trademark, etc. It may be text information.

<Third Embodiment>
FIG. 3 is an exploded perspective view showing a container provided in the balloon catheter set (third embodiment) of the present invention. Hereinafter, for convenience of explanation, the upper side in FIG. 3 is referred to as “upper (upper)” and the lower side is referred to as “lower (lower)”.

  Hereinafter, the third embodiment of the balloon catheter set of the present invention will be described with reference to this figure, but the description will focus on differences from the above-described embodiment, and the description of the same matters will be omitted.

  This embodiment is the same as the first embodiment except that the configuration of the catheter housing is different.

  As shown in FIG. 3, in this embodiment, the catheter housing 2 is a pair of split halves 24 and 25, which are joined together. The bonding method is not particularly limited, and examples thereof include a method using fusion (thermal fusion, high frequency fusion, ultrasonic fusion, etc.), a method using adhesion (adhesion with an adhesive or a solvent), and the like. . Each of the divided halves 24 and 25 can be formed by, for example, injection molding.

  Each of the divided halves 24 and 25 is configured by a member whose outer shape is a flat shape. A spiral groove 242 is formed on the back surface (lower surface) 241 of the divided half body 24. On the other hand, a spiral groove 252 is formed on the surface (upper surface) 251 of the divided half body 25. And the hollow part comprised by the groove | channels 242 and 252 is formed by joining the back surface 241 of the division | segmentation half body 24, and the surface 251 of the division | segmentation half body 25. FIG. In this hollow portion, the catheter body 201 of the balloon catheter 20 can be accommodated together with the stent 204.

  Information 4 is directly attached to the surface (upper surface) 243 of the divided half 24. The first item 41 is located farthest from the winding center 244 of the groove 242, the third item 43 is located most proximal from the winding center 244, and the second item 42 is the first Is located between the item 41 and the third item 43. Further, the contents of the first item 41 to the third item 43 are respectively along the winding direction of the groove 242.

  As for the 1st item 41-the 3rd item 43 attached | subjected to the catheter housing 2 of the above structures, the position shift with a corresponding stent internal diameter and a pressure value is prevented reliably. As a result, the first item 41 to the third item 43 can be accurately read.

  Thus, in the balloon catheter set 10 of this embodiment, it can be said that the catheter housing 2 has a function of preventing the positional deviation of the first item 41 to the third item 43.

<Fourth embodiment>
FIG. 4 is a plan view showing a fourth embodiment of the balloon catheter set of the present invention.

  Hereinafter, the fourth embodiment of the balloon catheter set of the present invention will be described with reference to this figure. However, the difference from the above-described embodiment will be mainly described, and description of similar matters will be omitted.

  The present embodiment is the same as the first embodiment except that there is information added as information regarding the balloon catheter.

Each marker 45 constitutes one quadrangle across the radial direction of the loop in the tubular body juxtaposed portion 22. In the configuration shown in FIG. 4, every other set of corresponding stent inner diameter and pressure value is surrounded by one marker 45. As an example, the inner diameter value 41b, the pressure value 42b, and the pressure value 43b are one marker 45. The inner diameter value 41d, the pressure value 42d, and the pressure value 43d are surrounded by one marker 45. The item name 41g, the unit 42g, and the unit 43g are also surrounded by one marker 45.

  For example, when an unintentional force acts on the catheter housing 2 from the state shown in FIG. 4, the positional relationship between the tubes 21 adjacent to each other may be shifted in the tube body juxtaposed portion 22. In this case, in the first item 41 to the third item 43, the corresponding stent inner diameter and pressure value are shifted, which is not preferable in reading the information 4.

  Also in each marker 45, the squares are hardly said to be squares. If the positional relationship between the tubes 21 is returned to such a level that the squares can be called squares, the corresponding stent inner diameter and pressure value can be obtained. The state is as shown in FIG. As a result, the first item 41 to the third item 43 can be accurately read.

  Thus, in the balloon catheter set 10 of this embodiment, it can be said that the marker 45 has a function as a “positional deviation notification marker” for notifying a positional deviation between the tubes 21.

  In addition, although the marker 45 is attached | subjected every other with respect to the group of a corresponding stent inner diameter and pressure value, it is not limited to this, For example, you may attach | subject with respect to each group, 2 It may be attached in pairs or more.
