Coronary sinus artificial valve for treating myocardial ischemia

Abstract

The invention discloses a coronary sinus artificial valve for treating myocardial ischemia. The coronary sinus artificial valve comprises an outer support and a spiral elastic sheet valve. The outer support comprises a first fixing part, a second fixing part and a plurality of supporting rods, wherein the first fixing part and the second fixing part are arranged along the center line of the outersupport, the supporting rods are distributed around the center line of the outer support; and each supporting rod comprises a plurality of sections sequentially connected from the first end to the second end, and any two adjacent sections are in smooth transition connection. The spiral elastic sheet valve is a one-way flow guide part attached to the interior of the outer support and has pressure compliance. When liquid flows to the second fixing part from the first fixing part of the outer support and the liquid pressure is lower than a preset pressure value, or when the liquid flows to the first fixing part from the second fixing part of the outer support, the one-way flow guide part is closed. The structural design of the artificial valve can effectively improve the perfusion and cardiacfunction of myocardial tissue and solve the problem that the artificial valve is difficult to fit with the anatomical structure of a human body.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a coronary sinus artificial valve for treating myocardial ischemia. Background technique [0002] Coronary heart disease is a disease that seriously endangers human health and is the number one killer of death in the world today. Nearly 20 million people die from it every year in the world. [0003] Coronary heart disease and its concurrent malignant arrhythmia and heart failure have increased the mortality and disability rate of patients, and added a heavy social and economic burden to the country. In the past 50 years, coronary artery revascularization therapy has made great progress. Coronary interventional therapy (PCI) or coronary artery bypass grafting (CABG) can significantly improve myocardial ischemia, relieve symptoms, and prolong life in patients with coronary heart disease. survival time. In 2010, more than 1 million people in the United ...
