Abstract

Abstract An anastomosis device is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes an expandable tube configured to have a graft vessel secured to the tube. The device has an expandable linkage positioned at one end of the device and expansion of this linkage causes a first radially extending flange to fold outward. This first flange abuts an interior wall of a target vessel and a second flange is formed which abuts an exterior wall of the target vessel trapping the target vessel between the two flanges and secures the end of the graft vessel into an opening in the wall of the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods and allows anastomosis to be performed in tight spaces.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 108 words
A system for performing anastomosis between a graft vessel and a target vessel, said system comprising: an anastomosis device, at least part of which is substantially cylindrical and configured to receive the graft vessel therethrough; a tool connected to said anastomosis device, wherein said tool is configured to create an opening in the target vessel from the outside; a holder tube connected to said anastomosis device; a pin connected to said holder tube; and a cam, wherein said cam includes at least one cam path and wherein said pin slides within at least one said cam path, wherein motion of said cam controls motion of said holder tube.
Claim 2
Independent Claim 108 words
A system for performing anastomosis between a graft vessel and a target vessel, said system comprising: an anastomosis device, at least part of which is substantially cylindrical and configured to receive the graft vessel therethrough; a tool connected to said anastomosis device, wherein said tool is configured to create an opening in the target vessel from the outside; a holder tube connected to said anastomosis device; a pin connected to said holder tube; and a cam, wherein said cam includes at least one cam path and wherein said pin slides within at least one said cam path, wherein motion of said cam controls motion of said holder tube.
Claim 3
Dependent Claim 16 words
The system of claim 1 , further comprising an expander slidable relative to said holder tube.
Claim 4
Dependent Claim 16 words
The system of claim 2 , wherein said expander and said holder tube are substantially coaxial.
Claim 5
Dependent Claim 27 words
The system of claim 2 , wherein said cam is operationally connected to said expander, and wherein motion of said cam controls the motion of said expander.
Claim 6
Dependent Claim 35 words
The system of claim 2 , further comprising a pin connected to said expander, wherein said cam includes at least one cam path, and wherein said pin slides within at least one said cam path.
Claim 7
Dependent Claim 11 words
The system of claim 1 , wherein said cam is hand-actuated.
Claim 8
Independent Claim 100 words
A system for performing anastomosis between a workpiece graft vessel having a lumen with an intimal lining and a target vessel, comprising: a sutureless anastomosis device, at least part of which is substantially tubular; and a tool for deploying said anastomosis device, wherein no element of said tool is configured to enter the lumen of the workpiece graft vessel, wherein said tool comprises a holder tube connected to said anastomosis device a pin connected to said holder tube; and a cam operationally connected to said pin, wherein motion of said cam along said pin controls motion of said holder tube.
Claim 9
Independent Claim 100 words
A system for performing anastomosis between a workpiece graft vessel having a lumen with an intimal lining and a target vessel, comprising: a sutureless anastomosis device, at least part of which is substantially tubular; and a tool for deploying said anastomosis device, wherein no element of said tool is configured to enter the lumen of the workpiece graft vessel, wherein said tool comprises a holder tube connected to said anastomosis device a pin connected to said holder tube; and a cam operationally connected to said pin, wherein motion of said cam along said pin controls motion of said holder tube.
Claim 10
Dependent Claim 27 words
The system of claim 7 , wherein at least a portion of said anastomosis device is configured to contact the intimal lining of the workpiece graft vessel.
Claim 11
Dependent Claim 26 words
The system of claim 7 , wherein said cam includes at least one cam path, wherein said pin slides within at least one said cam path.
Claim 12
Dependent Claim 16 words
The system of claim 7 , further comprising an expander slidable relative to said holder tube.
Claim 13
Dependent Claim 16 words
The system of claim 10 , wherein said expander and said holder tube are substantially coaxial.
Claim 14
Dependent Claim 26 words
The system of claim 10 , wherein said cam is operationally connected to said expander, and wherein motion of said cam controls motion of said expander.
Claim 15
Dependent Claim 25 words
The system of claim 10 , further comprising a pin connected to said expander, wherein said pin slides within at least one said cam path.
Claim 16
Dependent Claim 11 words
The system of claim 7 , wherein said cam is hand-actuated.
