Collapsible/expandable prosthetic heart valves with native calcified leaflet retention features
First Claim
Patent Images
1. A prosthetic heart valve comprising:
- an annular frame structure that is adapted for (1) delivery into a patient'"'"'s native heart valve annulus in a circumferentially collapsed condition, and (2) circumferential reexpansion when in the annulus, the frame structure having a proximal end adjacent an annulus portion and a distal end, the proximal end having a first diameter and the distal end having a second diameter greater than the first diameter;
a leaflet structure disposed in the frame structure; and
at least two fingers spaced apart, each of the at least two fingers having a first end coupled to the annulus portion of the frame structure and being cantilevered from the annulus portion.

Abstract
A prosthetic heart valve is circumferentially collapsible for less invasive delivery into a patient. The valve re-expands to operating size at the implant site in the patient. A frame structure of the valve includes restraining structure that can help to push one or more of the patient'"'"'s native heart valve leaflets radially outwardly so that this native leaflet tissue does not interfere with the operation or service life of the prosthetic valve.
