Abstract
Abstract A device for maintaining an opening in a first blood vessel in open position during a surgical procedure for suturing the opening in the first blood vessel to an opening in a second blood vessel. The device comprises: an elongate slender barrel with a straight longitudinal axis from the handle end to the tip end, a groove extending the length of the barrel, the groove ending in a slanting open cavity at the tip end, and a leaf spring clampattached to the barrel to clamp the blood vessel to the posterior convex surface of the tip.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
71 words
A blood vessel holder comprising: an elongate slender barrel having a substantially straight longitudinal axis from a distal handle end to a proximal tapered open cavity tip, for insertion into an opening in a blood vessel; and a clamping means in clamping alignment with the barrel convex surface of said cavity for providing secure, atraumatic, releasable attachment of the opening of the blood vessel to the proximal tip posterior convex surface.
Claim 2
Dependent Claim
71 words
A blood vessel holder comprising: an elongate slender barrel having a substantially straight longitudinal axis from a distal handle end to a proximal tapered open cavity tip, for insertion into an opening in a blood vessel; and a clamping means in clamping alignment with the barrel convex surface of said cavity for providing secure, atraumatic, releasable attachment of the opening of the blood vessel to the proximal tip posterior convex surface.
Claim 3
Dependent Claim
22 words
The blood vessel holder according to claim 1, wherein the clamping means is attached to the barrel by a barrel attachment means.
Claim 4
Dependent Claim
26 words
A blood vessel holder according to claim 2, wherein the barrel attachment means is a locking button and the clamping means is a leaf spring clamp.
Claim 5
Dependent Claim
18 words
A blood vessel holder according to claim 3, wherein the blood vessel holder is polycarbonate or stainless steel.
Claim 6
Dependent Claim
49 words
A blood vessel holder according to claim 1, wherein the barrel is provided with a longitudinal groove extending the length of the barrel to the distal end to the proximal tip, the groove opening out to form the protracted slanting open cavity at the proximal tip of the barrel.
Claim 7
Dependent Claim
36 words
The blood vessel holder according to claim 1, wherein the clamping means is substantially coterminous with the proximal tip of the barrel in spring releasable clamping relationship therewith for retaining the opening of the blood vessel.
Claim 8
Dependent Claim
23 words
A blood vessel holder according to claim 1, wherein the edges of the proximal tip and the protracted slanting open cavity are rounded.
Claim 9
Dependent Claim
23 words
The blood vessel holder according to claim 3, wherein the proximal clamping end of the leaf spring clamp is provided with securing teeth.
Claim 10
Dependent Claim
39 words
A blood vessel holder according to claim 3, wherein the leaf spring clamp attaches to the barrel by means of a pivot locking button, the barrel is polycarbonate and the locking button and the spring clamp are stainless steel.
Claim 11
Dependent Claim
41 words
The blood vessel holder according to claim 3, wherein the leaf spring clamp attaches to the barrel by means of a snap locking button, the barrel and the locking button are molded of polycarbonate and the spring clamp is stainless steel.
Claim 12
Dependent Claim
75 words
A tubular body structure holder comprising: an elongate slender barrel having a substantially straight longitudinal axis extending from a distal handle end to a proximal tapered open cavity tip for insertion into an opening in a tubular body structure; a clamping means in clamping alignment with the barrel convex surface of said open cavity for providing secure, atraumatic, releasable attachment of the opening of the tubular body structure to the proximal tip posterior convex surface.
Claim 13
Dependent Claim
75 words
A tubular body structure holder comprising: an elongate slender barrel having a substantially straight longitudinal axis extending from a distal handle end to a proximal tapered open cavity tip for insertion into an opening in a tubular body structure; a clamping means in clamping alignment with the barrel convex surface of said open cavity for providing secure, atraumatic, releasable attachment of the opening of the tubular body structure to the proximal tip posterior convex surface.
Claim 14
Dependent Claim
20 words
The holder according to claim 11 wherein the clamping means is attached to the barrel by a barrel attachment means.
Claim 15
Dependent Claim
23 words

Claim 16
Dependent Claim
19 words
The holder of claim 11 wherein edges of the proximal tip and the protracted slanting open cavity are rounded.
Claim 17
Dependent Claim
17 words
The holder of claim 11 wherein the barrel is polycarbonate and the clamping means is stainless steel.
Claim 18
Dependent Claim
74 words
A blood vessel holder comprising: a barrel having a substantially straight longitudinal axis from a distal end to a proximal tip end, an open cavity slanting to the proximal tip end of the barrel for insertion into an opening in a blood vessel; a clamping means in clamping alignment with the barrel convex surface of said open cavity for releasably securing an opening in a blood vessel to the proximal tip posterior convex surface.
Claim 19
Dependent Claim
74 words
A blood vessel holder comprising: a barrel having a substantially straight longitudinal axis from a distal end to a proximal tip end, an open cavity slanting to the proximal tip end of the barrel for insertion into an opening in a blood vessel; a clamping means in clamping alignment with the barrel convex surface of said open cavity for releasably securing an opening in a blood vessel to the proximal tip posterior convex surface.
