A surgical sutureless valve that is attached to a stent frame for delivery to a location in a patient using percutaneous implantation devices and methods.

Claims

1-8. -8. (canceled)

9. A stented valve comprising:

a compressible and expandable stent structure comprising a generally tubular body portion having an interior area, an external surface, a longitudinal axis, an inflow end, and an outflow end;

a tubular tissue material at least partially covering the external surface of the stent structure and extending beyond the outflow end of the stent structure; and

a plurality of leaflets attached to the interior area of the stent

10. The stented valve of claim 9, wherein the tubular tissue material comprises a bovine jugular vein.

11. The stented valve of claim 9. wherein the tubular tissue material comprises at least one aperture to allow for unobstructed fluid flow.

12. The stented valve of claim 10, comprising an aperture at each sinus area of the tubular tissue material to allow for unobstructed coronary fluid flow.

13. The stented valve of claim 9, further comprising a single suture line along which the proximal end of the leaflets and the tubular tissue material are secured to crowns at a proximal end of the stent structure.
