Abstract: Implant devices are provided for restoring compliance characteristics to blood vessels. An exemplary implant device includes an outer tubular frame having a diameter than varies along a longitudinal axis and a radially expandable tube disposed within the frame. Further disclosed are implant devices including a frame having an axially convex form that expands in diameter moving from first and second axial ends of the frame to a medial portion of the frame, and a cylindrical toroidal balloon member comprising one or more gas-filled chambers disposed at least partially within the frame. Further disclosed are implant devices including a tubular frame comprising a first axial segment and a second axial segment, a radially expandable tube disposed within the first axial segment of the frame, and a one-way valve disposed within the second axial segment of the frame.

Abstract: A device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. One or more portions of device or implant can expand and contract. For example, one or more portions of the device or implant can narrow during delivery and expand on implantation on the native heart valve. Delivery systems are configured to narrow and expand the one or more portions of the device or implant.
