Abstract

Abstract Endovascular grafting system having a capsule catheter (12) comprising a flexible elongate tubular member (16) having proximal and distal extremities and a capsule (36) mounted on the distal extremity of the tubular member (16). The capsule (36) is generally cylindrical in shape and is formed of a helical wrap of a metal ribbon (39). The wraps are bonded into a unitary capsule (36) permitting bending of said unitary capsule (36). A graft (121) is disposed within the capsule (36). The graft (121) is comprised of a tubular member (122) having proximal (123) and distal (124) ends. Hooks (151) are secured to the proximal (123) and distal (124) ends of the tubular member (122) and face in a direction outwardly towards the inner wall (37) of the capsule (36). A push rod (96,106) is disposed within the capsule catheter (12) and engages the graft (121) whereby upon relative movement between the push rod (96,106) and the capsule catheter (12), the graft (121) can be forced out of the capsule (36).

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 56 words
In an attachment system for securing a graft to a blood vessel, the attachment system including a sinusoidal wire frame having a plurality of longitudinally opposed apices and a plurality of lumen penetrating members, the invention comprising: configuring each apex with a helical coil spring configured to exert an outwardly directed bias on the wire frame.
Claim 2
Dependent Claim 33 words
The attachment system of claim 1, wherein said wire frame has a first end and a second end, said first end being affixed to said second end to provide a continuous wire frame.
Claim 3
Dependent Claim 20 words

Claim 4
Dependent Claim 44 words
The attachment system of any of claims 1 to 3, wherein each of said plurality of lumen penetrating members include a generally longitudinally extending arm having a first end and a second end and outwardly protruding hooks extending radially outward from said first end.
Claim 5
Dependent Claim 17 words
The attachment system of claim 4, wherein said outwardly protruding hooks terminate with a sharpened conical tip.
Claim 6
Dependent Claim 37 words
The attachment system of claim 1, wherein said wire frame includes a plurality of struts, each of said struts connecting one of said plurality of longitudinally opposed apices to another of said plurality of longitudinally opposed apices.
Claim 7
Dependent Claim 21 words
The attachment system of claim 6, wherein each of said lumen penetrating members are individually affixed to one of said struts.
Claim 8
Dependent Claim 20 words
The attachment system of claim 7, wherein each of said lumen penetrating members are welded to said plurality of struts.
Claim 9
Dependent Claim 22 words
The attachment system of claim 1, wherein said wire frame is configured to be sewn to an inside wall of the graft.
Claim 10
Dependent Claim 59 words
The attachment system of any of the preceding claims, wherein each of said lumen penetrating members include a generally longitudinally extending arm having a first end and a second end and an outwardly protruding hook extending radially outward from said first end, said hook having a terminal end directed towards a plane perpendicular to a wall of the graft.
Claim 11
Dependent Claim 22 words
The attachment system of any of the preceding claims, wherein a first apex is longitudinally staggered from a second and adjacent apex.
