Abstract

A prosthetic valve including a replacement valve having a tubular valve body wall, an expandable stent having a framework with first and second ends, and suturing holding the framework to the valve body at the first and second ends. The suturing at the first end is colored differently from the suturing at the second end.

Claims

1. A prosthetic valve and delivery system, the valve mountable to the delivery system in either first or second orientations, wherein the prosthetic valve comprises:

a valve member;

an expandable stent having a first portion and a second portion; and

a plurality of sutures holding the valve member to the stent at the first and second portions, wherein the sutures at the first portion are colored differently than the sutures at the second portion;

wherein the delivery system includes at least one colored visual indicator that corresponds with the sutures at the first portion of the stent, wherein the colored visual indicator is generally the same color as the sutures at the first portion of the stent; and

wherein the at least one colored visual indicator is located such that when the prosthetic valve is mounted in the first orientation relative to the delivery system, the at least one colored visual indicator is adjacent to the first portion of the stent.

2. The prosthetic valve and delivery system of claim 1, wherein the first orientation of the prosthetic valve relative to the delivery system corresponds to a correct valve orientation, and wherein the second orientation of the prosthetic valve relative to the delivery system corresponds to an incorrect valve orientation.

3. The prosthetic valve and delivery system of claim 1, the expandable stent further comprising an intermediate portion between the first and second portions

wherein the plurality of sutures include an intermediate suture located at the intermediate portion to attach the valve member to the stent at the intermediate portion.

4. The prosthetic valve and delivery system of claim 1, wherein the colored visual indicator is a symbol.

5. The prosthetic valve and delivery system of claim 1, wherein the colored visual indicator is a pattern.

6. The prosthetic valve and delivery system of claim 1, wherein the first portion of the stent comprises an inflow end of the prosthetic valve.

7. The prosthetic valve and delivery system of claim 1, wherein the first portion of the stent comprises an outflow end of the prosthetic valve.
