Abstract
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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
51 words
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.
Claim 2
Dependent Claim
51 words
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.
Claim 3
Dependent Claim
18 words
The endoprosthesis of claim 1 , wherein the elongated member has parallel straight sides defining a constant width.
Claim 4
Dependent Claim
22 words
The endoprosthesis of claim 1 , wherein the elongated member has non-parallel straight sides defining a narrowing width towards the pointed end.
Claim 5
Dependent Claim
41 words
The endoprosthesis of claim 1 , wherein the elongated member is resilient so as to be compressed into a position within the circumference of the frame element when constrained and to extend outside the circumference of the frame element when unconstrained.
Claim 6
Dependent Claim
15 words
The endoprosthesis of claim 1 , wherein the pointed end includes at least one barb.
Claim 7
Dependent Claim
12 words
The endoprosthesis of claim 1 , wherein the pointed end is sharpened.
Claim 8
Dependent Claim
16 words
The endoprosthesis of claim 1 , wherein the endoprosthesis is integrally formed into an endoluminal prosthesis.
Claim 9
Dependent Claim
13 words
The endoprosthesis of claim 1 , wherein the frame element defines a cylinder.
Claim 10
Dependent Claim
20 words
The endoprosthesis of claim 8 , wherein the cylinder is expandable radially without reliance upon relative movement of overlapping structure.
Claim 11
Dependent Claim
46 words
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.
Claim 12
Dependent Claim
46 words
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.
Claim 13
Dependent Claim
21 words
The connector of claim 10 , wherein the sides of the hook are parallel and straight and define a constant width.
Claim 14
Dependent Claim
24 words
The connector of claim 10 , wherein the sides of the hook are non-parallel and straight and define a narrowing width towards the point.
Claim 15
Dependent Claim
15 words
The connector of claim 10 , wherein the points is formed in an arrowhead configuration.
Claim 16
Dependent Claim
13 words
The connector of claim 10 , wherein the connector element defines a cylinder.
Claim 17
Dependent Claim
20 words
The connector of claim 14 , wherein the cylinder is expandable radially without reliance upon relative movement of overlapping structure.
Claim 18
Dependent Claim
36 words
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.
Claim 19
Dependent Claim
36 words
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.
Claim 20
Dependent Claim
14 words
The endoluminal prosthesis of claim 16 , wherein the frame element defines a cylinder.
Claim 21
Dependent Claim
21 words
The endoluminal prostrhesis of claim 17 , wherein the cylinder is expandable radially without reliance upon relative movement of overlapping structure.
Claim 22
Independent Claim
72 words
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.
Claim 23
Independent Claim
72 words
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.
Claim 24
Dependent Claim
27 words
The method of claim 19 , wherein the bending step further comprises compressing the frame element onto a mandrel having offset pins for bending the elongate members.
Claim 25
Dependent Claim
15 words
The method of claim 19 , further comprising the step of: sharpening the pointed end.
