Wire connection device for mitral valve procedure {Wire connection device for mitral valve procedure}

The present invention relates to a wire connection device for mitral valve treatment that connects different wires, and a wire connection device for mitral valve treatment that is fixed by preventing the movement of an integrated rope and a guide wire connected to a coronary artery protector used for heart disease. It is about.

The heart is composed of two atriums and two ventricles, and is connected to four blood vessels, such as the aorta, the vena cava, the pulmonary artery, and the pulmonary veins, and becomes a passage for blood.

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

As the heart repeats contraction and relaxation, the heart acts as a pump, and blood flows through the blood vessels. During the systolic phase of the heart, blood in the heart advances into the blood vessels, where blood flows from the right heart to the right ventricle and from the left heart to the left ventricle.

However, if the membrane between the atrium and the ventricle does not work properly, the blood of the ventricles will flow back to the systolic of the heart. When the tricuspid valve between the right atrium and the right ventricle does not work properly and the blood of the right ventricle refluxes into the right atrium, it is called 'tricuspid regurgitation'. It is said.

In order to treat mitral valve regurgitation, the present inventor proposed in Korean Patent Registration No. 10-1116867 'Tissue protection mechanism of coronary veins and tricuspid valves, a knot delivery mechanism and a device for mitral valve circle large treatment including the same'. In the above patent, a circle large chamber (circle loaf) forming a circle around the relative vein, coronary vein, ventricular septum, right ventricle, right atrium, and inferior vena cava is used as a tube for coronary vein (CS tube) and a tube for tricuspid valve (TV tube). It was proposed to protect the damage of human tissues by wrapping, and to transfer the knot tied at the end of the circle large thread to the upper end of the tissue protection mechanism using a knot delivery mechanism to complete the circle large procedure. The tension of the circle large thread is applied to obtain the effect of constricting the mitral valve, which reduces the incomplete closure of the valve by bringing the two leaflets of the mitral valve closer together. This principle has a very similar effect to the surgical treatment of direct mitralization of the mitral valve, which results in a therapeutic effect that reduces the backflow of blood through the mitral valve. However, the arch portion, which is the coronary vein protector (coronary artery protector) proposed in the patent, has a disadvantage that it cannot secure safety because it is a structure that can be easily moved by the flow of the heart while being loosely fitted in a circle large thread.

To overcome these drawbacks, the present inventor proposed and patented a circle large rope for mitral valve circle large procedure in which an arch-shaped coronary artery protector is integrated (Korean Registered Patent No. 10-1581025).

The procedure of using the device of the patent filed above is, first, accessing the right atrium through the jugular vein using a guide wire, and then through the 'coronary sinus' and 'proximal septal vein', After passing through the right ventricular outflow tract (RVOT) to the right atrium to form a 'reverse alpha-shaped loop', the micro catheter is gradually pushed along the guide wire. Next, the guide wire is pulled out of the body (b) Then only the micro catheter remains. Then, the 'coronary artery protector integrated rope' is inserted into the micro catheter. When the coronary artery protector-integrated rope is fully inserted, the microcatheter is pulled out of the body. Then, finally, a tissue protective device (CSTV tube) is inserted to complete the mitral valve coronary vein operation.

However, when a coronary artery protector-integrated rope is inserted into the micro catheter lumen, it is not easy to insert the coronary artery protector into the catheter because it is larger than the microcatheter inner diameter. Therefore, if the coronary artery protector is inserted into the inside of the micro-catheter to the connection part of the coronary artery protector, and the micro-catheter and the all-in-one rope are pulled at the same time, the coronary artery protector is in the right position (if it is in the position to protect the coronary artery), the Apply the method of removing the micro catheter by pulling only the catheter toward the inferior vena cava. This method introduces the complexity and discomfort of the procedure, such as the micro catheter insertion step, the integral rope insertion and correct positioning step, and the micro catheter removal step, in order to place the integral rope in place.

In addition, in Korean Patent No. 10-1677193, a 'rope for a coronary artery protector integrated with a mitral valve procedure and a loop for connecting a guide wire and a device for manufacturing the coronary artery protector integrated circle large rope in place in a heart' Proposed.

The patent connects the integral rope and the guide wire using a heat shrink tube to integrate the integrated rope and guide wire with a single line, but this is the complexity and inconvenience of applying heat from the outside to shrink the heat shrink tube. There is this.

Accordingly, there is a need to propose a device for integrating a coronary artery protector-integrated rope and a guide wire more simply.
