Replacement prosthetic heart valve, system and method of implant
First Claim
1. A prosthetic heart valve comprising:
- a collapsible support structure, the support structure having an axial length terminated by an inflow end and an outflow end;
leaflets mounted to the support structure; and
a plurality of anchors directly mounted to the support structure, the plurality of anchors including a radially outwardly extending first anchor disposed proximate to the inflow end and a radially outwardly extending second anchor proximate to the outflow end, wherein the first anchor includes a first configuration having a first size and the second anchor includes a second configuration having a second size, and wherein the first size is different than the second size.

Abstract
A prosthetic heart valve for functionally replacing a previously implanted prosthetic heart valve is disclosed. The prosthetic heart valve includes a collapsible support structure with leaflets and anchors mounted to the support structure. The support structure also includes an inflow end and an outflow end. The anchors include a radially outwardly extending first anchor proximate to the inflow end and a radially outwardly extending second anchor proximate to the outflow end. The first anchor includes a first configuration and the second anchor includes a second configuration where the first configuration is different than the second configuration. The previously implanted prosthetic heart valve serves as a platform for securement of the prosthetic heart valve to the patient'"'"'s native tissue.

17. A prosthetic heart valve comprising:
-
a collapsible support structure, the support structure having an axial length terminated by an inflow end and an outflow end; wherein the collapsible support structure is transitionable from a collapsed state to an expanded state having an enlarged diameter as compared to the collapsed state; leaflets mounted to the support structure; and a plurality of anchors mounted to the support structure, wherein the plurality of anchors are adapted to be retracted when the support structure is in the collapsed state and to extend radially outwardly when the support structure is in the expanded state, and wherein the plurality of anchors including a radially outwardly extending first anchor disposed proximate to the inflow end in the expanded state and a radially outwardly extending second anchor proximate to the outflow end in the expanded state, and further wherein a size of a first anchor configuration differs from a size of a second anchor configuration. - View Dependent Claims (18, 19)
