Abstract
Abstract An anastomosis cuff for performing a vascular anastomosis procedure includes a ridge of material that extends in the radial direction. The ridge can be easily grasped with forceps or a hemostat to immobilize the cuff during an anastomosis procedure. Alternately, the anastomosis cuff can be grasped between gripping fingers of a manipulator tool designed to surround the cuff such that the ridge is trapped between and grasped by the gripping fingers.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
86 words
A cuff suitable for use in an anastomosis procedure, comprising: a hollow portion having a length extending in a longitudinal axial direction of the cuff and a continuous inner surface; and a non-annular outwardly extending ridge directly connected on an exterior wall of the hollow portion, the non-annular outwardly extending ridge having a planar portion that extends along the exterior wall of the hollow portion in a direction parallel to the longitudinal axial direction such that the ridge is graspable to immobilize and position the cuff.
Claim 2
Dependent Claim
86 words
A cuff suitable for use in an anastomosis procedure, comprising: a hollow portion having a length extending in a longitudinal axial direction of the cuff and a continuous inner surface; and a non-annular outwardly extending ridge directly connected on an exterior wall of the hollow portion, the non-annular outwardly extending ridge having a planar portion that extends along the exterior wall of the hollow portion in a direction parallel to the longitudinal axial direction such that the ridge is graspable to immobilize and position the cuff.
Claim 3
Dependent Claim
23 words
The cuff of claim 1, wherein the ridge extends in the longitudinal axial direction for less than the entire length of the cuff.
Claim 4
Dependent Claim
13 words
The cuff of claim 2, wherein the hollow portion has a cylindrical shape.
Claim 5
Dependent Claim
15 words
The cuff of claim 3, wherein the ridge is monolithically formed with the hollow portion.
Claim 6
Dependent Claim
26 words
The cuff of claim 3, wherein the ridge is formed separately from the hollow portion and is attached to the exterior wall of the hollow portion.
Claim 7
Dependent Claim
13 words
The cuff of claim 1, wherein the hollow portion has a cylindrical shape.
Claim 8
Dependent Claim
13 words
The cuff of claim 1, wherein the hollow portion has a conical shape.
Claim 9
Dependent Claim
15 words
The cuff of claim 1, wherein the ridge is monolithically formed with the hollow portion.
Claim 10
Dependent Claim
26 words
The cuff of claim 1, wherein the ridge is formed separately from the hollow portion and is attached to the exterior wall of the hollow portion.
Claim 11
Dependent Claim
14 words
The cuff of claim 1, wherein a vessel is passable through the hollow portion.
Claim 12
Dependent Claim
22 words
The cuff of claim 10, wherein an interior diameter of the hollow portion is between approximately 0.5 mm and approximately 1 cm.
Claim 13
Dependent Claim
22 words
The cuff of claim 11, wherein an outer diameter of the hollow portion is between approximately 0.6 mm and approximately 1.1 cm.
Claim 14
Dependent Claim
14 words
The cuff of claim 1, wherein the ridge is pierceable by a suture needle.
Claim 15
Dependent Claim
15 words
The cuff of claim 1, wherein the cuff is formed of a biologically inert material.
Claim 16
Dependent Claim
14 words
The cuff of claim 1, wherein the cuff is formed of a resorbable material.
Claim 17
Dependent Claim
16 words
The cuff of claim 1, further comprising a flange on the radial end of the ridge.
Claim 18
Dependent Claim
26 words
The cuff of claim 1, wherein the ridge extends along the exterior wall along a line substantially parallel to a longitudinal axis of the hollow portion.
Claim 19
Dependent Claim
77 words
A cuff suitable for use in an anastomosis procedure, comprising: a hollow portion having a length extending in a longitudinal axial direction of the cuff and a continuous inner surface; and a non-annular outwardly extending ridge directly connected on an exterior wall of the hollow portion, the non-annular outwardly extending ridge having a flange on a radial end thereof, the ridge extending along the exterior wall of the hollow portion and being graspable to immobilize the cuff.
Claim 20
Dependent Claim
77 words
A cuff suitable for use in an anastomosis procedure, comprising: a hollow portion having a length extending in a longitudinal axial direction of the cuff and a continuous inner surface; and a non-annular outwardly extending ridge directly connected on an exterior wall of the hollow portion, the non-annular outwardly extending ridge having a flange on a radial end thereof, the ridge extending along the exterior wall of the hollow portion and being graspable to immobilize the cuff.
Claim 21
Dependent Claim
14 words
