Markers for prosthetic heart valves

摘要

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.

1. A replacement prosthetic heart valve for engagement with a structure of an original prosthetic heart valve that comprises a tubular base from which multiple commissure posts extend in an axial direction, wherein at least one of the commissure posts comprises at least one visually detectable commissure marker, the replacement prosthetic heart valve comprising:
a stent structure comprising:
a generally tubular body portion having a longitudinal axis; andat least one visually detectable and directionally distinguishable 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 and directionally distinguishable marker of the stent structure is positionable relative to the at least one visually detectable commissure marker of the original prosthetic heart valve and is directionally distinguishable such that the directionally distinguishable marker appears differently if the directionally distinguishable marker is on a portion of the generally tubular portion towards the viewer than if the directional distinguishable marker is on a portion of the generally tubular portion away from the viewer;wherein the visually detectable and directionally distinguishable marker of the replacement heart valve is radiopaque; andwherein the visually detectable and directionally distinguishable marker of the replacement heart valve is c-shaped, wherein the c-shape is transverse to the longitudinal axis and configured to indicate a rotational orientation around the longitudinal axis of the replacement heart valve.
