Abstract
A prosthetic valve includes a radially expandable and compressible frame, a leaflet assembly comprising a plurality of leaflets coupled to the frame, and an outer skirt positioned around an outer surface of the frame. The outer skirt includes a tissue layer and a non-tissue layer. The tissue layer has a fibrous side and a smooth side. The non-tissue layer is coupled to the smooth side of the tissue layer. The outer skirt is positioned so that the fibrous side of the tissue layer faces away from the frame and the non-tissue layer faces towards the frame.
Claims20
A prosthetic valve, comprising:
- a radially expandable and compressible frame;
- a leaflet assembly comprising a plurality of leaflets coupled to the frame;
- and
- an outer skirt positioned around an outer surface of the frame,
- wherein the outer skirt comprises a tissue layer and a non-tissue layer.
A method of making a prosthetic heart valve, comprising:
- forming an outer skirt by attaching a non-tissue layer to a tissue layer;
- and
- mounting the outer skirt to an outer surface of an annular frame.
A method comprising:
- delivering a prosthetic device in a radially compressed state to a target location;
- and
- radially expanding the prosthetic device to a radially expanded state, wherein the prosthetic device comprises:
- a radially expandable and compressible frame;
- a leaflet assembly comprising a plurality of leaflets coupled to the frame;
- and
- an outer skirt positioned around an outer surface of the frame, wherein the outer skirt comprises a tissue layer and a non-tissue layer.
