TRUNCATED CONE HEART VALVE STENT

摘要

主权项

1. A method comprising:
delivering to a native annulus of an atrioventricular valve of a heart a prosthetic valve having a self-expanding body having a proximal end and a distal end, a valve disposed in the body, and a plurality of self-expanding atrial anchoring elements distributed circumferentially about, and extending radially outwardly from, the proximal end of the body, and a plurality of anchoring sutures, each anchoring suture having a first end and a second end, the first end being attached to the distal end of the body, the delivering including disposing the atrial anchoring elements on an atrium side of the native annulus and the sutures on a ventricle side of the native annulus; allowing the body to self-expand into engagement with the native annulus; disposing the first end of each of the sutures outside the heart; and with the sutures, applying tension between the wall of the ventricle and the anchoring elements to fix the prosthetic valve in the native annulus.
