Percutaneous aortic valve replacement device

Abstract

The invention provides a new percutaneous aortic valve replacing device which is characterized by the rational designation, convenient usage and low operational danger, which is to solve problems of inconvenient stitching of valve and cradle and high danger of using saccule to expand aortic valve in current aortic valve replacing device, the device is an automatic buckling cradle carrying biological valve, comprising cradle in nickel-tantalum alloy framework and trilobular one-way opening valve composed of pig heart bag. The nickel-tantalum alloy possesses functions of fixing and supporting, the trilobular valve is fixed tightly in the cradle. The product is characterized by the small injury, high safety, reduced complication caused by aortic valve replacement, and wide application prospect.

Description

technical field

[0001] The invention relates to a medical device, in particular to an artificial aortic valve used in the Department of Cardiology, which can replace the aortic valve without surgery, in particular to a percutaneous aortic valve replacement device. Background technique

[0002] Since Starr and Harken succeeded in replacing the mitral valve and aortic valve for patients with artificial valves respectively in 1960, surgical valve replacement is the most effective method for the treatment of severe heart valve diseases, and valve replacement is performed for more than 100,000 patients every year Operation. Artificial valves are divided into two categories: biological valves and mechanical valves. There are more than 100 types, each with its own advantages and disadvantages in clinical use, and the vast majority of artificial valve replacement operations are performed with the support of a systemic pulmonary circulation machine, which makes infants with complicat...
