Abstract
An apparatus for endovascularly replacing a patient'"'"'s heart valve comprises an anchor having an outer surface and an inner surface. The anchor is expandable from a collapsed delivery configuration to a fully deployed configuration. A first locking element and a second locking element are attached to the inner surface of the anchor. The first locking element is engageable with the second locking element. At least one of the first locking element and the second locking element has a curved outer surface. Methods for attaching the second locking element to the anchor are also provided.

14. A method of attaching a locking member to an anchoring element of an apparatus for endovascularly replacing a patient'"'"'s heart valve, the method comprising:
-
placing a locking member in contact with an inner surface of the anchoring element, wherein the locking member comprises a plate with a curved outer surface, an inner surface, and a thickness therebetween with a plurality of holes extending through the thickness of the plate, wherein the plurality of holes comprises a first plurality of holes and a second plurality of holes, wherein the first plurality of holes and the second plurality of holes are separated by a portion of the curved outer surface;
wherein the curved outer surface contacts the inner surface of the anchoring element; andthreading a thread-like member through the plurality of holes such that the thread-like member only crosses the outer surface between the first plurality of holes and the second plurality of holes once to securely attach the locking member to the anchoring element. - View Dependent Claims (15, 16, 17, 18, 19, 20)
