Prosthetic heart valve and systems and methods for delivering the same
First Claim
1. A system comprising:
- a collapsible and expandable prosthetic heart valve body having a proximal end and a distal end;
first and second leaflet clips, each of the first and second leaflet clips being coupled to the prosthetic heart valve body and configured to be transitioned between a first condition in which the body can be inserted into a native annulus of an atrioventricular valve of a heart, and a second condition, in which the leaflet clip is adapted to capture a native valve leaflet such that the native valve leaflet is engaged between the leaflet clip and the body when the body is disposed in the native annulus of the atrioventricular valve of the heart;
first and second control elements, the first control element being operably coupled to the first leaflet clip and the second control element being operably coupled to the second leaflet clip, each of the first and second control elements having a length sufficient to extend through the 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 first control element being configured to allow a user to transition the first leaflet clip from the first condition to the second condition and the second control element being configured to allow the user to transition the second leaflet clip from the first condition to the second condition; and
an elongate member having a proximal end and a distal end, the distal end configured to be disposed in the ventricle of the heart during deployment of the prosthetic heart valve body and the proximal end configured to extend outside the heart, the elongate member defining a first control element lumen extending from the proximal end to the distal end, and a second control element lumen extending from the proximal end to the distal end, the second control element lumen being separate from the first control element lumen,wherein the first control element is disposable in the first control element lumen and extendable out the proximal end of the elongate member, and the second control element is disposable in the second control element lumen and extendable out the proximal end of the elongate member.

Abstract
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.

14. A system for delivering a prosthetic heart valve to a native valve annulus of a heart, the valve including a self-expanding wire frame body having a proximal end and a distal end, and a leaflet clip, the system comprising:
-
an elongate member having a first end and a second end, the first end configured to be disposed in a ventricle of a heart during deployment of the prosthetic heart valve and the second end configured to extend outside the heart, the elongate member defining a tether lumen extending from the first end to the second end of the elongate member and at least one control element lumen extending from the first end to the second end of the elongate member, the at least one control element lumen being separate from the tether lumen; and a first control element having a first end and a second end, the first control element being disposed in the at least one control element lumen and operably coupled to the leaflet clip, the first control element having a length sufficient to extend from the leaflet clip through the at least one control element lumen and out a wall of the ventricle when the body is disposed in the native valve annulus of the heart, wherein the first control element is configured to allow a user to transition the leaflet clip between a first condition in which the body can be inserted into a native annulus and a second condition in which the leaflet clip is adapted to capture a native valve leaflet such that the native valve leaflet is engaged between the leaflet clip and the body when the body is disposed in the native annulus of the heart. - View Dependent Claims (15, 16, 17, 18, 19)
