Markers for Prosthetic Heart Valves
First Claim
1. A replacement prosthetic heart valve for engagement with a structure of a an original prosthetic heart valve that comprises at least one visually detectable marker, the replacement heart valve comprising:
- a stent structure comprising;
a generally tubular body portion; and
at least one visually detectable marker on a portion of the stent structure;
andat least two leaflets attached within the interior area of the tubular body portion of the stent structure;
wherein the at least one visually detectable marker of the stent structure is positionable relative to at least one visually detectable marker of the original prosthetic heart valve.

Abstract
A replacement prosthetic heart valve for engagement with a structure of an original prosthetic heart valve that includes at least one visually detectable marker. The replacement heart valve includes a stent structure having a generally tubular body portion and at least one visually detectable marker on a portion of the stent structure, and at least two leaflets attached within the interior area of the tubular body portion of the stent structure. At least one visually detectable marker of the stent structure is alignable with at least one visually detectable marker of the original prosthetic heart valve.

- 10. A replacement prosthetic heart valve in combination with an original heart valve, wherein the original valve comprises at least one visually detectable marker and wherein the replacement heart valve comprises at least one visually detectable marker that is alignable with the at least one marker of the original heart valve.

16. A replacement heart valve comprising:
-
a stent structure comprising; a generally tubular body portion; and at least one visually detectable deformable skirt surrounding at least a portion of the tubular body portion; and at least two leaflets attached within the interior area of the tubular body portion of the stent structure; wherein the at least one deformable skirt is deformable in response to pressure of the skirt against a native valve annulus.

17. A method of implanting a replacement prosthetic heart valve within an original prosthetic heart valve comprising at least one visually detectable marker, the method comprising:
-
positioning a replacement prosthetic heart valve in an internal area defined by a generally tubular structure of the original prosthetic heart valve, wherein the replacement heart valve comprises; a stent structure comprising; a generally tubular body portion; and at least one visually detectable marker on a portion of the stent structure; and at least two leaflets attached within the interior area of the tubular body portion of the stent structure; adjusting the location of the replacement heart valve by aligning at least one visually detectable marker of the replacement heart valve with at least one visually detectable marker of the original heart valve.
