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.
Claims16
A mechanism for securing an endoprosthesis within a corporeal lumen, the mechanism comprising:
- a frame element with incisions formed therein, the frame element having a substantially tubular shape and lacking concentrically overlapping structure;
- the incisions forming an elongated member having a pointed end, the elongated member being bounded by the frame element;
- and
- the elongated member bent away from said frame element wherein the elongate member has a permanent curve.
A connector for fastening a device to corporeal tissues, said connector comprising:
- a substantially tubular body lacking concentrically overlapping structure;
- a hook having two sides and a point and being bounded by the tubular body;
- said sides and said point defined by narrow slits in the connector;
- and
- said hook having a permanent bend that forms a permanent curve.
An endoluminal prosthesis, comprising:
- a substantially tubular frame element, the frame element lacking concentrically overlapping structure;
- and
- at least one protrusion cut out of said frame element having a resiliently flexible bend formed therein, wherein the at least one protrusion has a permanent curve the at least one protrusion being bounded by the frame element and the at least one protrusion having a pointed end.
