Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heart valve regurgitation device,

The present invention relates to a valve regurgitation procedure and a pacemaker lead fixation device. More particularly, the present invention relates to a device for performing a mitral valve regurgitation and tricuspid valve regurgitation, a valve regurgitation procedure for securing the pacemaker lead to the ventricular septum, ≪ / RTI >

The heart consists of two atria and two ventricles and is connected to four blood vessels, the aorta, the vena cava, the pulmonary artery,

Based on the ventricular septum in the center of the heart, one is divided into the right atrium and right ventricle, and the other is divided into left atrium and left ventricle. There is a tricuspid membrane between the right atrium and the right ventricle, and there is a mitral valve between the left atrium and the left ventricle.

As the heart repeats contraction and relaxation, the heart acts as a pump, causing blood to flow along the blood vessels. In the systole of the heart, the blood moves from the heart to the blood vessel, from the right heart to the right ventricle to the pulmonary artery, from the left heart to the aorta from the left ventricle.

However, if the membrane between the atrium and the ventricle does not work properly, the blood in the ventricle will flow back into the systole of the heart. If the tricuspid valve between the right atrium and the right ventricle is not functioning properly and the blood in the right ventricle is refluxed into the right atrium, it is called tricuspid valve regurgitation. If the left atrium and the left ventricular mitral valve do not function properly, '.

Tricuspid regurgitation usually occurs in patients with mitral valve regurgitation. Patients with heart valve disease may experience atrial fibrillation, arrhythmia, heart failure, etc., which can be treated by inserting a pacemaker into the body.

Tricuspid regurgitation, mitral regurgitation, and heart failure are associated with each other and may have three diseases at the same time. Therefore, a device for treating three diseases at once is required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a valve regurgitation procedure and a pacemaker lead fixation device according to a preferred embodiment of the present invention. Referring to FIG. 1, a valve regurgitation procedure and a pacemaker lead fixation apparatus according to a preferred embodiment of the present invention includes a circlid wire 10, a coronary sinus tube 20, a tricuspid valve tube 30, a pacemaker lead 50, .

The circlid wire 10 is connected in a circular shape as shown in the figure, in the sense that it is connected to the coronary sinus, the ventricular septum, and the tricuspid membrane so as to form a circle. When the circular large wire 10 is pushed or pulled from the upper part, it maintains the proper tension according to the heart size and the shape of the heart of the patient and tightens the mitral annulus by tightly holding the mitral annulus. Thus, it is possible to treat mitral regurgitation.

An arch 12 is formed on one side of the circular large wire 10. The circumferential wire 10 is inserted into the coronary sinus. When the coronary artery is positioned below the coronary sinus, a considerable external pressure is applied to the coronary artery by the circumferential wire 10. The arcuate portion 12 is for preventing this and protecting the coronary artery.

The coronary sinus tube 20 is formed to have a lumen into which the circular wire 10 can be inserted, and the lower part is inserted into the coronary sinus to protect the coronary sinus.

The tricuspid valve tube 30 has a through hole therein and penetrates the orifice caused by incomplete closing of the tricuspid valve to reach the ventricular septum. The tricuspid valve tube 30 includes a blocking portion 32. The blocking portion 32 is a portion for blocking a space generated due to an incomplete closing of the tricuspid membrane. The blocking portion 32 can treat tricuspid regurgitation.

A stopper (60) is provided at the lower end of the tricuspid membrane tube (30) to prevent the end of the tricuspid membrane tube (30) from penetrating into the ventricular septum. This allows the tricuspid membrane tube 30 to float around the tricuspid membrane without close contact, thereby preventing the tricuspid membrane tube 30 from damaging the tricuspid membrane.

2 is a perspective view of a pacemaker lead according to a preferred embodiment of the present invention.

2, the end of the pneumatic heart lead 50 has a screw shape for easily penetrating the ventricular septum, and the outside of the body 52 is formed of an insulator. Needless to say, the body portion 52 may not include an insulator. In the case of the heartbeat lid 50 not including the insulator, the thickness of the body 52 is thin. The pacemaker lead 50 can sense the electrical signal of the heart and can sense the position of the heath and deliver electrical stimulation to the heath or ventricular septum.

The pacemaker lead 50 is inserted into the tricuspid valve tube 30 and the bottom is outside the tricuspid valve tube 30. A direction adjusting device 54 is provided at an upper end of the pedometer lid 50 and a lower portion is bent or expanded as the direction adjusting device 54 is adjusted. Accordingly, it is possible to determine the position of the heath by sensing the electrocardiogram of the ventricular septum by moving the lower part of the heartbeat lid 50 by adjusting the direction adjusting device 54. The heartbeat lid 50 can be positioned at the detected position of the heath, .

The upper portion of the pneumatic valve lead 50 is coupled to the tricuspid valve tube 30 and the lower portion thereof is separated. Accordingly, by adjusting the direction adjusting device 54 coupled to the upper portion of the pedometer lid 50, the lower portion can be bent or unfolded to sense the position of the heath.

Other components except for the pedometer lead 50 are the same as those described above with reference to FIGS.

4 is a perspective view of a valve regurgitation procedure and a pacemaker lead fixation device according to another preferred embodiment of the present invention.

4, a valve regurgitation procedure and a pacemaker lead fixation apparatus according to a preferred embodiment of the present invention includes a circulation wire 10, a coronary sinus tube 20, a tricuspid valve tube 30, a lead insertion tube 40, , And a heartbeat lid (50).

The lead insertion tube 40 is formed with a lumen for inserting the pneumatic stem lead 50 therein. The upper portion of the lead insertion tube 40 is inserted into the tricuspid valve tube 30, Is located outside the tube (30) and has its lower end facing the ventricular septum.

The pacemaker lead 50 is inserted into the lead insertion tube 40. When the end reaches the ventricular septum, the pacemaker lead 50 moves to detect the electrocardiogram of the ventricular septum by adjusting the direction adjusting device 54. [ After the position of the heath is sensed, the end of the heartbeat lid 50 is fixed to the heath.

Components other than the lead insertion tube 40 are as described above in Fig.

[ After the position of the heath is sensed, the end of the heartbeat lid 50 is fixed to the heath.

FIG. 6 is a flowchart of a method of performing a procedure using a valve regurgitation procedure and a pacemaker lead fixation device according to a preferred embodiment of the present invention.

Referring to FIG. 6, step (S10) of inserting the circular wire into the coronary sinus is a step of moving the circular wire 10 to the superior vein, the coronary sinus, and the septal vein.

And may include a balloon catheter (not shown) to facilitate movement of the circular wire 10. The balloon catheter (not shown) prevents blood flow in the coronary sinus and swells the coronary sinus so that the septal vein, which is generally difficult to see, can be easily seen.

The circular wire 10 passes through the septal vein through the ventricular septum and into the right ventricle. In order to pass the ventricular septum, the circular wire 10 has a pointed end, but a perforated catheter (not shown) is required when it is difficult to penetrate the ventricular septum using only the circular large wire 10. A puncture catheter (not shown) serves to support the circulatory wire 10 when the ventricular septum is punctured, so that the circadian wire 10 passes through the ventricular septum more easily.

Next, step (S20) of capturing a circle large wire using a capture catheter. The capture catheter 70 is formed with a mesh net 72 as shown in FIG. 7, and the mesh net 72 can be narrowed or unfolded by a force applied to the capture catheter 70 outside the body. The capture catheter 70 moves to the inferior vein, the tricuspid valve, and the right ventricle, and may further include a safe zone pass catheter (not shown) for securely moving the capture catheter 70 within the body. The mesh network 72 is narrowed when it moves to the right chamber and spreads in the right ventricle, and the circle large wire 10 is inserted into the mesh network 72. The mesh network 72 is narrowed again and the circulation wire 10 is captured and then exited through the inferior vein. At this time, one end of the circumferential wire 10 is positioned in the superior vein and the other end is positioned in the inferior vein.

The following is a step (S30) of adjusting the tension by guiding the circular wire to the superior vein. The circular wire 10 guided to the inferior vein is guided to the superior vein by a snare or forcep inserted in the superior vein and both ends are located in vitro via the superior vein. Therefore, the circular wire 10 passes through the superior vein, the coronary sinus, the septal vein, the ventricular septum, and the right ventricle, and is located in the superior vein. Tension or retraction of the circlid wire (10) to maintain proper tension according to the size of the patient's heart and the shape of the heart, tightening the mitral annulus to tightly hold it, and allowing the mitral valve to close completely to treat mitral regurgitation.

The following is a step (S40) of inserting a cardiac valve lead fixation device and a valve regurgitation procedure. The coronary sinus tube 20 and the tricuspid valve tube 30 are inserted into the coronary sinus tube 20 and the tricuspid valve tube 30, respectively, Is inserted into the body along the circular large wire (10). At this time, it is preferable that the pacemaker lead 50 combined with the normal tricuspid valve tube 30 is inserted in the right atrium direction like the tricuspid valve tube 30.

The stopper 60 is coupled to the lower end of the tricycle membrane tube 30 and may be coupled to the lower portion of the tricuspid membrane tube 30. This allows the tricuspid membrane tube 30 to float without being tightly attached around the tricuspid membrane, thereby preventing damage to the tricuspid membrane. In addition, the tricuspid valve tube 30 includes the blocking portion 32, which penetrates the orifice resulting from incomplete closing of the tricuspid membrane, thereby allowing the tricuspid valve to be completely closed. The blocking portion 32 may be in the form of a blocking film, a blocking balloon, or the like.

Finally, it is the step of fixing the heartbeat lid (S50). The heartbeat lid 50 may be provided with a direction adjusting device 54 at its upper end so as to be bent or unfolded. The cardiac pacemaker lid 50 moves the lower part by the direction adjusting device 54 to sense the electrocardiogram of the ventricular septum to determine the position of the heath and fix the end of the heartbeat lid 50 to the detected position of the heath.

According to the above-described steps, one device can perform mitral regurgitation, tricuspid regurgitation, and pacemaker lead fixation. It can be used for at least one of the three purposes of three purposes: simultaneous three procedures with one device, treatment of mitral regurgitation, treatment of tricuspid regurgitation, and pacing of the pacemaker for the treatment of heart failure.

Further, since the end of the cardiac pacemaker lead is inserted into the heath by sensing the electrocardiogram, the electrical stimulation can be transmitted more efficiently.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
