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.
Claims21
An endoprosthesis for use within a corporeal lumen, comprising:
- a graft;
- a frame element with incisions formed therein attached to the graft;
- the incisions forming an elongated member having a pointed end;
- and
- the elongated member bent away from said frame element, the elongate member having a permanent constant radius curve.
A connector for fastening a device to corporeal tissues, said connector comprising:
- a hook having two sides and a point;
- said sides and said point defined by narrow slits in the connector;
- and
- said hook having a curve, the hook forming a permanent constant radius curve.
An endoluminal prosthesis, comprising:
- a frame element;
- and
- at least one protrusion cut out of said frame element having a resiliently flexible curve formed therein, the at least one protrusion forming a permanent constant radius curve.
A method to manufacturing a hook for attaching to corporeal lumen, the hook being intergral with a frame element and predisposed outwardly therefrom, comprising the steps of:
- forming an elongate member in the frame element by cutting two sides and a pointed end;
- bending the elongate member such that the pointed end extends outwardly from the frame element;
- and
- heating the frame element and elongate member until the bend is permanently set.
