Problems solved by technology

Also, over time, the native valve leaflets may harden (eg, change modulus) due to, for example, calcification, resulting in undesired turbulence, eddies, and / or additional undesired flow patterns within the heart
Even further, such degeneration and / or sclerosis of the native valve leaflets may in some cases lead to degeneration of the leaflets of the prosthetic heart valve

Embodiment Construction

[0032] Described herein are devices, systems, and methods for immobilizing, controlling, capturing, or otherwise manipulating native heart valve leaflets as the prosthetic heart valve is delivered to or disposed within the native annulus of an atrioventricular valve of the heart.

[0033] In some embodiments, a prosthetic heart valve (also referred to herein as "prosthetic valve") includes a self-expanding wire frame body (also referred to herein as "body") disposed on A valve 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 transition between a first configuration in which the prosthetic heart valve is insertable into the heart and a second configuration in which the body When disposed in the native annulus of an atrioventricular valve of the heart, the leaflet clip is arranged to capture a native leaflet between the leaflet clip and the...

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.
