Abstract

Claims (14)

1 . A sealing element for a prosthetic heart valve, comprising:

a first woven portion comprising at least one weft yarn woven together with a first plurality of warp yarns to form a first plurality of loops, wherein the first plurality of loops are shape-set such that the first plurality of loops extend outwardly from the sealing element; and

a second woven portion that is spaced apart from the first woven portion along a longitudinal axis of the prosthetic heart valve when the sealing element is disposed on the prosthetic heart valve, and the second woven portion comprises a second plurality of loops that are shape-set such that the second plurality of loops extend outwardly from the sealing element.

2 . The sealing element of claim 1 , wherein the first plurality of loops extend from and return to a first woven portion of the sealing element comprising the first plurality of warp yarns.

3 . The sealing element of claim 1 , wherein the at least one weft yarn is a textured yarn.

4 . The sealing element of claim 3 , wherein the textured yarn comprises a plurality of fibers having a diameter of 1 μm to 20 μm.

5 . A prosthetic heart valve, comprising:

an annular frame having an inflow end, an outflow end, and a longitudinal axis;

a leaflet structure positioned within the frame and secured to the frame; and

the sealing element of claim 1 disposed circumferentially around the frame and secured to the frame.

6 . The prosthetic heart valve of claim 5 , wherein the sealing element comprises a plurality of circumferentially extending rows of loops, the rows of loops being spaced apart along the longitudinal axis of the frame.

7 . The prosthetic heart valve of claim 5 , wherein the second plurality of loops extend from and return to the second woven portion.

8 . The prosthetic heart valve of claim 5 , wherein the second plurality of loops of the second woven portion is circumferentially offset from the first plurality of loops of the first woven portion.

9 . The prosthetic heart valve of claim 5 , wherein the sealing element further comprises a semi-woven portion disposed between the first woven portion and the second woven portion, wherein the at least one weft yarn is not interwoven with warp yarns of the semi-woven portion at locations of loops of the first plurality of loops.
