Abstract
A sealing member for a prosthetic heart valve includes an annular fabric body having a first circumferential portion and a second circumferential portion. The first circumferential portion extends circumferentially around the annular fabric body and is resiliently stretchable in a direction along the longitudinal axis of the annular fabric body between an expanded configuration of the prosthetic heart valve and a collapsed configuration of the prosthetic heart valve. The second circumferential portion extends around the annular fabric body and is circumferentially offset from the first circumferential portion, the second circumferential portion being resiliently stretchable in a circumferential direction between the collapsed configuration of the prosthetic heart valve and the expanded configuration of the prosthetic heart valve.
