PROSTHETIC VALVE FOR REPLACING A MITRAL VALVE

摘要

Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricular anchors extending outwardly from the ventricular end of the main body. Each ventricular anchor can have a proximal end portion connected to the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial so as to define a first bend, and a free distal end portion that extends from the intermediate portion. The distal end portion can comprise a first section, a second section, and a second bend between the first and second sections, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.

主权项

1. A prosthetic device for implanting at a native mitral or tricuspid valve region of the heart, the native valve region having a native valve annulus and native leaflets, the prosthetic device comprising:
a main body configured for placement within the native valve annulus, the main body having a lumen extending between an atrial end and a ventricular end; an atrial cap that extends radially outwardly from the atrial end; and a plurality of ventricular anchors spaced angularly around a circumference of the main body, each ventricular anchor having a proximal end portion connected to the main body proximate the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial end so as to define a first bend, and a distal end portion extending from the intermediate portion, the distal end portion comprising a first section, a second section, and a second bend between the first and the second section, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.
