Abstract
An improved hook provides for the attaching of endoluminal prosthesis within corporeal lumens. The hook is integrally formed with framing structure and is preset into an outward bend, but is resiliently flexible so as to form a substantially straight profile when compressed. The hook is capable of impinging upon the corporeal lumen and thereby securing the prosthesis. The hook may be configured for intraluminal delivery and deployment. A novel method of manufacturing said hook is also provided.

20. A mechanism for securing an endoprosthesis to corporeal tissue of a corporeal lumen, the mechanism comprising:
-
a tubular frame;
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;
a stress relief cut-out formed through the tubular frame and located adjacent the first end of the elongate member; and
an incision formed through the tubular frame, the incision extending from the stress relief cut-out and around the second end. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 33)

29. A mechanism for securing an endoprosthesis to corporeal tissue of a corporeal lumen, the mechanism comprising:
-
a tubular frame with a stress-relief cut-out formed through the tubular frame;
an elongate member attached to the tubular frame adjacent the stress relief cut-out, the elongate member having a pointed end movable away from the tubular frame so as to impinge upon corporeal tissue, the elongate member formed on the tubular frame by an incision through the frame and extending from the stress relief cut-out to the second end. - View Dependent Claims (30, 31, 32, 34, 35, 36, 37)

38. A method of manufacturing a mechanism for securing an endoprosthesis to corporeal tissue of a corporeal lumen, the method comprising:
forming an elongate member on a tubular frame having a pointed end movable from the frame so as to impinge upon corporeal tissue, including removing material from the frame to form an incision extending around the pointed end and removing additional material from the frame to form a stress relief cut-out located at an end of the incision.
- 41. The method of claim 42, wherein forming the elongate member includes making the stress relief cut-out wider than the incision.
