Abstract

A prosthetic heart valve includes a non-collapsible annular frame extending in a longitudinal direction between an inflow edge and an outflow edge, and a valve assembly connected to the frame. The frame includes a plurality of annularly spaced commissure posts adjacent the outflow edge, each of the commissure posts including a tip and a post slot spaced apart from the tip. The prosthetic heart valve further includes a radiopaque element including an elongated main body having a first end and a second end. The radiopaque element may extend around the tip and through the post slot of at least one of the commissure posts so that a portion of the main body extends between the slot and the tip. Alternatively or additionally, a radiopaque element may be positioned adjacent a base of the frame.

First claim

The invention claimed is:

1. A prosthetic heart valve, comprising:
a non-collapsible annular frame extending in a longitudinal direction between an inflow edge and an outflow edge, the frame having an annular base adjacent the inflow edge and a plurality of annularly spaced commissure posts adjacent the outflow edge, each of the commissure posts having a tip and a post slot within the commissure post and spaced apart from the tip;
a radiopaque wire extending partially around the base so as to form a first wire wrap and a second wire wrap, the first wire wrap being connected to the second wire wrap at a first looped end and at a second looped end spaced apart from the first looped end, the first looped end being secured to the second looped end by a suture; and
a valve assembly connected to the frame and including a plurality of leaflets connected to the commissure posts.

2. The prosthetic heart valve of claim 1 , wherein the first wire wrap is adjacent the inflow edge and the second wire wrap is positioned between the first wire wrap and the outflow edge.

3. The prosthetic heart valve of claim 1 , wherein the prosthetic heart valve further comprises one or more radiopaque indicators indicating a characteristic of the prosthetic heart valve, the one or more radiopaque indicators comprising one of a washer, a knot, or a bead.

4. The prosthetic heart valve of claim 1 , further comprising a radiopaque element including an elongated main body having a free first end and a free second end, the radiopaque element extending around the tip and through the post slot of at least one of the commissure posts so that a portion of the main body extends between the post slot and the tip.

5. The prosthetic heart valve of claim 4 , wherein the first end and the second end of the radiopaque element are tucked beneath the portion of the main body such that the first end and the second end of the radiopaque element are positioned between the portion of the main body and a surface of the at least one commissure post and the first end is not directly connected to the second end.

6. The prosthetic heart valve of claim 4 , wherein the radiopaque element is a metal wire.

7. The prosthetic heart valve of claim 4 , wherein the first end and the second end of the radiopaque element are intertwined to secure the radiopaque element to the tip of the at least one of the commissure posts.

8. The prosthetic heart valve as claimed in claim 7 , wherein the portion of the main body of the radiopaque element overlaps the intertwined first and second ends.

9. The prosthetic heart valve of claim 7 , wherein the intertwined first and second ends are positioned within the post slot of the at least one of the commissure posts.

10. The prosthetic heart valve of claim 1 , further comprising a plurality of apertures along at least one of the post slots, and a radiopaque wire extending through at least one of the apertures.

11. The prosthetic heart valve of claim 10 , wherein the radiopaque wire extends through a multiplicity of the apertures.

12. The prosthetic heart valve of claim 10 , wherein the radiopaque wire extends through each of the apertures.

13. The prosthetic heart valve as claimed in claim 1 , wherein the radiopaque wire extends partially around the base to form first, second third and fourth wire wraps, the first, second, third and fourth wire wraps being connected to one another to form the first looped end and the second looped end.
