HEART VALVE DELIVERY SYSTEM WITH VALVE CATHETER

摘要

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.

1. An assembly for treating a native valve in a human heart, comprising:
a prosthetic heart valve including an expandable frame, a valve structure, a first end portion, and a second end portion, wherein the first end portion has plurality of apertures formed therein; and a delivery apparatus, comprising:
a valve catheter having a proximal end portion and a distal end portion;a plurality of flexible extension arms having first and second end portions, wherein the first end portions of the flexible extension arms are coupled to a cylindrical coupling element, the second end portions of the flexible extension arms are releasably coupled to the prosthetic heart valve, and the coupling element is connected to the distal end portion of the valve catheter;a plurality of slidable wires extending distally from the distal end portion of the valve catheter; anda plurality of release members coupled to the distal end portion of the valve catheter, wherein each of the release members extends through a respective aperture of the prosthetic heart valve, thereby forming a releasable connection between the prosthetic heart valve and the slidable wires.
