Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
53 words
A graft for use in vascular anastomosis comprising: a cylindrical metal braided frame; and suture retention structures at distal ends of said braided frame which provide suture sites for anastomosis wherein said suture retention structures include suture rings; and said suture rings are metal and are welded to distal ends of said frame.
Claim 2
Dependent Claim
53 words
A graft for use in vascular anastomosis comprising: a cylindrical metal braided frame; and suture retention structures at distal ends of said braided frame which provide suture sites for anastomosis wherein said suture retention structures include suture rings; and said suture rings are metal and are welded to distal ends of said frame.
Claim 3
Dependent Claim
65 words
A graft for use in vascular anastomosis comprising: a cylindrical metal braided frame; and suture retention structures at distal ends of said braided frame which provide suture sites for anastomosis wherein said cylindrical metal braided frame includes welds at distal ends to prevent frame unraveling; said graft is coated with a bio-compatible and bio-stable material; and said braided frame is formed from a compliant material.
Claim 4
Dependent Claim
65 words
A graft for use in vascular anastomosis comprising: a cylindrical metal braided frame; and suture retention structures at distal ends of said braided frame which provide suture sites for anastomosis wherein said cylindrical metal braided frame includes welds at distal ends to prevent frame unraveling; said graft is coated with a bio-compatible and bio-stable material; and said braided frame is formed from a compliant material.
Claim 5
Dependent Claim
21 words
