US 2015/0148896 A1 · AORTIC INSUFFICIENCY REPAIR DEVICE AND METHOD

Abstract

This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In a representative embodiment, a support frame configured to be implanted in a heart valve comprises an annular main body formed by a plurality of angled struts, the main body including a plurality of peaks formed by the intersection of respective adjacent struts. The support frame further comprises one or more leaflet-engaging mechanisms configured to engage leaflets of the heart valve. The support frame can be radially expandable and collapsible.

A support frame configured to be implanted in a heart valve comprising a plurality of leaflets, the support frame comprising:

an annular main body formed by a plurality of angled struts, the main body including a plurality of peaks formed by the intersection of respective adjacent struts;
and
one or more leaflet-engaging mechanisms located beneath respective peaks of the support frame, each of the one or more leaflet-engaging mechanisms defining a leaflet-receiving space between two opposing surfaces for engaging portions of adjacent leaflets therebetween, wherein the leaflet-receiving space is adjustable to facilitate placement of the portions of the adjacent leaflets within the leaflet-engaging mechanism;
wherein the support frame is radially expandable and collapsible.
