Devices and methods for delivery of valve prostheses
First Claim
1. An implantation device, comprisinga valve prosthesis comprising a support frame radially expandable between a compact condition and an expanded condition, the support frame having an outer surface and a longitudinal axis along an inflow-outflow direction and defining a central orifice about the longitudinal axis and at least one valve clasper movably attached to the support frame such that during valve delivery the at least one valve clasper is movable relative to the support frame along the longitudinal axis and between a nesting position with the outer surface of the support frame and an engagement position with a native cardiac valve sinus wherein the at least one valve clasper is physically separated from the support frame, anda delivery device comprisinga control unit;
- andat least one track wire, the at least one track wire having a proximal end attached to the control unit and a distal end for contact with the at least one valve clasper.

Abstract
A valve prosthesis and implantation device, and methods for use are provided. The devices may be used for transcatheter delivery of an aortic valve prosthesis or transapical delivery of a mitral valve prosthesis. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis, reducing the extent of imaging needed during the implantation procedure.
