Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
An anchor for securing a graft to a vessel wall, comprising: a body, having a proximal end, a distal end, and a longitudinal axis; at least one proximal arm on the body for resisting distal movement of the anchor through tissue; and at least one distal arm on the body for resisting proximal movement of the anchor through tissue; wherein the proximal and distal arms are moveable between a first position in which the cross section of the anchor is minimized and a second position in which the arms are deployed.
Claim 2
Dependent Claim
91 words
An anchor for securing a graft to a vessel wall, comprising: a body, having a proximal end, a distal end, and a longitudinal axis; at least one proximal arm on the body for resisting distal movement of the anchor through tissue; and at least one distal arm on the body for resisting proximal movement of the anchor through tissue; wherein the proximal and distal arms are moveable between a first position in which the cross section of the anchor is minimized and a second position in which the arms are deployed.
Claim 3
Dependent Claim
19 words
An anchor as in claim 1 , wherein the arms are biased in the direction of the second position.
Claim 4
Dependent Claim
24 words
An anchor as in claim 1 , wherein the arms are moveable into the second position in response to axial shortening of the anchor.
Claim 5
Dependent Claim
18 words
An anchor as in claim 1 , wherein the arms and body are integrally formed from a tube.
Claim 6
Dependent Claim
17 words
An anchor as in claim 1 , comprising from two proximal arms to about six proximal arms.
Claim 7
Dependent Claim
17 words
An anchor as in claim 1 , comprising from two distal arms to about six distal arms.
Claim 8
Dependent Claim
12 words
An anchor as in claim 1 , comprising a nickel titanium alloy.
Claim 9
Dependent Claim
26 words
An anchor as in claim 1 , wherein the at least one proximal arm and the at least one distal arm are integral with the body.
