Abstract:
1. A mechanism for securing an endoprosthesis to corporeal tissue of a corporeal lumen, the mechanism comprising: a tubular frame having a central axis; an elongate member having a first end attached to the tubular frame and a second end that is movable away from the tubular frame so as to impinge upon corporeal tissue; an incision formed through the tubular frame, the incision creating an opening in the tubular frame extending from a beginning of the incision at the first end, around the second end, and to an ending of the incision at the first end of the elongate member, wherein the elongate member includes a middle portion between the first end and the second end; and a pair of stress relief cut-outs formed through the tubular frame and located adjacent the first end of the elongate member at both ends of the incision; wherein the incision defines the first and second ends and a point on the second end of the elongate member that have a combined shape that corresponds to a shape of the opening in the tubular frame; wherein a length from the first end to the point on the second end of the elongate member is oriented along the central axis; and wherein the tubular frame has a compressed configuration at which the second end of the elongate member extends a first distance from the frame in a first direction and at which the middle portion extends a second distance from the frame in a second direction opposite the first direction.
