Abstract
A valve prosthesis, implantation device, and methods for use are provided. The devices described herein may be used for transcatheter delivery of an aortic valve prosthesis or transapical delivery of a mitral valve prosthesis. The implantation device can utilize movable claspers for both positioning and anchoring the valve prosthesis, reducing the extent of imaging needed during the implantation procedure.
Claims22
A valve prosthesis, comprising:
- a support frame having an outer surface and defining a central orifice, the support frame radially being expandable to an expanded configuration;
- flexible leaflets attached to the support frame to permit one-way flow through the orifice when the support frame is in its expanded configuration;
- a coupling component;
- and
- a valve clasper movably coupled to the support frame via the coupling component such that the valve clasper is movable relative to the support frame along a longitudinal axis of the valve prosthesis between a nesting position with the outer surface of the support frame and an engagement position with a valve annulus wherein the valve clasper is physically separated from the support frame.

- flexible leaflets attached to the support frame to permit one-way flow through the orifice when the support frame is in an expanded configuration;
- a coupling component;
- and
- a valve anchor movably coupled to the support frame via the coupling component to permit the valve anchor to be movable relative to the support frame along the longitudinal axis from an engagement
- configuration in which the valve anchor and the support frame are collapsed against an implantation device to a nesting configuration in which the support frame is positioned within the valve anchor, the valve anchor being physically separate from the support frame.
