Abstract

The invention discloses a transthoracic bicuspid valve balloon dilatation catheter assembly and a technology thereof. The assembly comprises a balloon catheter and a guiding bougie. One end of the balloon catheter is a handle, and the other end of the balloon catheter is a balloon. The handle is in a Y shape, and the handle comprises a guide wire cavity and a filling cavity; the far end of the outer catheter is connected with the near end of the balloon, an inner catheter transversely penetrates through the balloon, and a tip end is formed at the far end of the balloon; the balloon is a cylinder, and the connection of the balloon and the outer catheter has a gradient, and two developing rings are fixedly installed inside the inner catheter inside the balloon; a heat shrink tube is arrangedbetween the handle and the catheter as transition; the guiding bougie is formed by connecting the control handle and the control guide wire. The balloon dilatation catheter assembly can complete biscupid valve narrow separation technology, the transthoracic intervention path is short, operation is easy, the balloon catheter is made of nylon materials, the explosion pressure is large, the safety is higher, meanwhile, no excessive fitting operation is needed, and various complications are reduced.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a transthoracic mitral valve balloon expansion catheter assembly and its technology. Background technique

[0002] Mitral valve stenosis is a structural change of the heart's mitral valve due to various reasons, resulting in a smaller, limited or obstructed opening of the mitral valve, resulting in obstruction of left atrial blood flow, decreased left ventricular return blood volume, and increased left atrial pressure. A series of abnormal changes in the structure and function of the heart. The most common etiology is rheumatism, which mostly occurs in 20-40 years old, and women are more than men. There is no specific cure for this disease at present, and cardiac interventional surgery and surgical treatment can be cured. Percutaneous balloon mitral valvuloplasty (PBMV) has gradually replaced the closed dissection. It has been clinically verified for more than 30 years. ...
