    Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the stent which includes a plurality of self-expanding struts and an annular sealing membrane. Each strut has a first end coupled to a distal end of the stent and a second end not coupled to the stent. Each anti-paravalvular leakage component is moveable between a compressed configuration and a deployed configuration. In the compressed configuration, each strut extends distally away from the distal end of the stent. In the deployed configuration, each strut extends proximally away from the distal end of the stent. In an embodiment hereof, the deployed strut has a C-shape and is twisted such that the C-shape lies in a plane substantially along or tangential with the outer surface of the stent. In another embodiment hereof, the deployed strut is rolled-up and extends radially away from the outer surface of the stent.

    Abstract: A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.
