PROSTHETIC HEART VALVE AND SYSTEMS AND METHODS FOR DELIVERING THE SAME

摘要

A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.

1. A prosthetic heart valve comprising:
a self-expanding wire frame body having a proximal end and a distal end; a valve disposed in the body; a leaflet clip coupled to the body and configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the body when the body is disposed in a native annulus of an atrioventricular valve of a heart; and a control element operably coupled the leaflet clip and having a length sufficient to extend from the leaflet clip through a ventricle of the heart and out a wall of the ventricle when the body is disposed in the native annulus of the atrioventricular valve of the heart, the control element configured to allow a user to transition the leaflet clip from its first configuration to its second configuration when the body is disposed in the native annulus of the atrioventricular valve of the heart.
