Abstract
An implantable prosthetic valve may comprise a valve body having a proximal end, a distal end, an outer surface, and an inner surface facing a flow channel, and a skirt including a first level forming at least a portion of the outer surface of the valve body and configured to be thromboresistant and a second level forming at least a portion of the outer surface of the valve body and configured to allow tissue ingrowth with the second level. A plurality of prosthetic valve leaflets may be positioned within the flow channel and extend inward from the inner surface of the valve body.
Claims22
An implantable prosthetic valve comprising:
- a valve body having a proximal end, a distal end, an outer surface, and an inner surface facing a flow channel, and a skirt including a first level forming at least a portion at the outer surface of the valve body and configured to be thromboresistant and a second level forming at least a portion of the outer surface of the valve body and configured to allow tissue ingrowth with the second level;
- and
- a plurality of prosthetic valve leaflets positioned within the flow channel and extending inward from the inner surface of the valve body.
An implantable prosthetic valve comprising:
- a plurality of prosthetic valve leaflets;
- and
- a valve body having a proximal end, a distal end, an outer surface, and an inner surface facing a flow channel in which the plurality of prosthetic valve leaflets are positioned, and a skirt forming at least a portion of the outer surface of the valve body and being coupled to the plurality of prosthetic valve leaflets with one or more bioresorbable couplers.
An implantable prosthetic valve comprising:
- a valve body having an outer surface and an inner surface facing a flow channel, and a skirt including an exterior surface forming at least a portion of the outer surface of the valve body and configured to be porous to allow tissue ingrowth within the exterior surface and an interior surface that is configured to be thromboresistant;
- and
- a plurality of prosthetic valve leaflets positioned within the flow channel and extending inward from the inner surface of the valve body;
- wherein the skirt includes a plurality of layers.
