摘要：
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.
