Abstract: A paravalvular leak resistant prosthetic heart valve system including a stent frame, a valve structure and a sealing mechanism. The stent frame has a surface. The valve structure is associated with the stent frame. The sealing mechanism at least partially extends over the surface of the stent frame. The sealing mechanism includes at least one semi-permeable membrane and an osmotic gradient driving material.

Abstract: A prosthetic heart valve includes a stent frame with a first end portion, a second end portion, and a central portion extending between the first end portion and the second end portion. The stent frame extends in a first direction of a longitudinal axis of the prosthetic heart valve from the first end portion to the second end portion. The prosthetic heart valve further includes a support arm coupled to the stent frame, a valve structure associated with the stent frame, and a seal configured to expand to a swelled orientation by fluid passing into the seal.
