Prosthetic valve and prosthetic valve implanting method

Abstract

A prosthetic valve, solving the technical problem of an existing prosthetic valve, when implanted in a certain valve site, not being adaptive to the physiological anatomy condition of the heart, being difficult to mount and fix properly and being easy to become displaced, and consequently affecting the function of the valve. The prosthetic valve comprises an annular frame () which has a mesh structure and can radially expand to deform; a connection line () is provided on the frame (); the prosthetic valve is connected and fixed to an anatomical structure of a mounting position of a human body by means of the connection line (); the connection line () surrounds the outside of the frame () to form several connection portions which extend out along the radial direction of the frame (); the space surrounded by the connection portions can receive the thickness of the anatomical structure. The prosthetic valve is connected and fixed by means of the connection line () to an anatomical structure of a mounting position in a human body, e.g. a vessel wall, being mounted stably and being applicable to a patient on whom a valve replacement surgery is difficult to perform, e.g. a pulmonary artery stenosis patient.
