Abstract
A heart valve prosthesis for replacing a diseased native valve in a patient. The valve prosthesis includes a compressible and expandable frame structure and an anchor connected to an outer periphery of the frame structure. The anchor comprises a helical wire having a free end. The valve may further include a valve segment mounted within the frame structure and expanded with the frame structure. The frame structure may be configured for receiving a valve segment.

A method of replacing a diseased native valve of a patient, the method comprising:
- loading a valve prosthesis into a delivery catheter, the valve prosthesis comprising an expandable frame structure carrying a biocompatible valve segment and an anchor attached to an outer periphery of the frame structure, the anchor comprising a wire having a free end;
- delivering the valve prosthesis to a target location above a native valve;
- inserting the valve prosthesis through the native valve to a position posterior the native valve;
- rotating the wire such that the free end wraps around at least a portion of chordae tendineae below the valve;
- and
- expanding the frame structure including the valve segment within the native valve.
