Mechanism for securing to a corporeal lumen and method of manufacturing
First Claim
Patent Images
1. 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, wherein the elongate member includes a middle portion between the first end and the second end;
a stress relief cut-out formed through the tubular frame and located adjacent the first end of the elongate member;
an incision formed through the tubular frame, the incision extending from the stress relief cut-out and around the second end; and
the tubular frame having 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.

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.

9. 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 cutout, the elongate member having a pointed end movable away from the tubular frame so as to impinge upon corporeal tissue and a middle portion adjacent the pointed end, 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; and the tubular frame having a compressed configuration at which the pointed 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
