Abstract

A stented valve including a compressible and expandable stent frame having a generally tubular body portion having an interior area and a longitudinal axis, a bioprosthetic valve positioned at least partially within the interior area of the tubular body portion of the stent frame and having an inner wall from which a plurality of leaflets extend; and a tubular covering material including a first portion extending from a first end of the stent frame to a second end of the stent frame, and a second portion extending beyond the second end of the stent frame.

Claims

1. A stented valve comprising:

a compressible and expandable stent frame comprising a generally tubular body portion having an interior area and a longitudinal axis;

a bioprosthetic valve positioned at least partially within the interior area of the tubular body portion of the stent frame and comprising an inner wall from which a plurality of leaflets extend; and

a tubular covering material comprising a first portion extending from a first end of the stent frame to a second end of the stent frame, and a second portion extending beyond the second end of the stent frame.

2. The stented valve of claim 1, wherein the tubular covering material comprises pericardial material.

3. The stented valve of claim 1, wherein the stent frame comprises a shape memory material.

4. A method of implanting a stented valve comprising the steps of:

providing a stented valve comprising;

a compressible and expandable stent frame comprising a generally tubular body portion having an interior area and a longitudinal axis;

a bioprosthetic valve positioned at least partially within the interior area of the tubular body portion of the stent frame and comprising an inner wall from which a plurality of leaflets extend; and

a tubular covering material comprising a first portion extending from a first end of the stent frame to a second end of the stent frame, and a second portion extending beyond the second end of the stent frame;

inserting the second portion of the tubular covering material into an aortic opening having an edge;

wrapping the second portion of the tubular covering material over the edge of the aortic opening; and

attaching an adjacent tubular structure to the second portion of the tubular covering material.
