CARDIAC VALVE PROSTHESIS

Document Type and Number:

WIPO Patent Application WO/2019/033989

Kind Code:

A1

Abstract:

Disclosed is a cardiac valve prosthesis for replacing a natural valve in a human body. The natural valve comprises a valve ring (6), and the cardiac valve prosthesis comprises an expandable stent body (1), artificial leaflets (2) fixed on the stent body (1), and at least one outwardly protruding structure (3) arranged on a side wall of the stent body (1). After the cardiac valve prosthesis is implanted into the human body, the at least one outwardly protruding structure (3) is arranged above the valve ring (6) to limit the position of the cardiac valve prosthesis. The outwardly protruding structure (3) is arranged above the valve ring (6) to limit the position of the cardiac valve prosthesis. By means of the bottom of the outwardly protruding structure (3) abutting against the top of the valve ring (6) in a expanded form, the cardiac valve prosthesis can be prevented from shifting towards the ventricle, effectively solving the problem of the anchorage of the cardiac valve prosthesis in a released position without causing calcification of a root of the valve, and also achieving the stable implantation of the cardiac valve prosthesis.
