Abstract

An assembly for treating a native heart valve can include a prosthetic valve and a delivery apparatus. The prosthetic valve can include an expandable frame, a valve structure, a first end with apertures formed therein, and a second end. The delivery apparatus can include a valve catheter, flexible extension arms, slidable wires, and release members. First ends of the arms can be coupled to a cylindrical coupling element, second ends of the arms can be releasably coupled to the prosthetic valve, and the coupling element can be connected to the distal end of the valve catheter. The slidable wires can extend distally from the distal end of the valve catheter. The release members can be coupled to the distal end of the valve catheter and can extend through a respective aperture of the prosthetic valve, thereby forming a releasable connection between the prosthetic valve and the slidable wires.
