Abstract
Abstract Methods and devices for harvesting blood vessels using balloons to hold the blood vessel and to dissect and mobilize the blood vessel from surrounding tissue. A small balloon catheter is inserted into the blood vessel lumen to and inflated in order to hold the blood vessel, and an everting balloon dissector is everted over the blood vessel. Eversion of the balloon dissector over the blood vessel pushing surrounding body tissue away from the blood vessel.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
82 words
A device for enveloping an elongate structure, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing said elongate balloon in its uninflated state being folded, said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape adapted to envelope the elongate structure, said inflated balloon having a central lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 2
Independent Claim
82 words
A device for enveloping an elongate structure, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing said elongate balloon in its uninflated state being folded, said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape adapted to envelope the elongate structure, said inflated balloon having a central lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein said elongate balloon is made from a nonelastomeric material.
Claim 4
Dependent Claim
19 words
The device of claim 1 wherein said elongate balloon in its uninflated state is folded within the tubular member.
Claim 5
Dependent Claim
21 words
The device of claim 1 wherein said elongate balloon in its uninflated state is longitudinally and coaxially folded within the housing.
Claim 6
Dependent Claim
18 words
The device of claim 1 wherein said elongate balloon in its uninflated state is folded in accordion folds.
Claim 7
Independent Claim
82 words
A device for enveloping an elongate structure, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing, said elongate balloon in its uninflated state being folded, said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape adapted to envelope the elongate structure, the torodial balloon having a central lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 8
Independent Claim
82 words
A device for enveloping an elongate structure, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing, said elongate balloon in its uninflated state being folded, said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape adapted to envelope the elongate structure, the torodial balloon having a central lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 9
Dependent Claim
15 words
The device of claim 6 wherein said elongate balloon is made from a nonelastomeric material.
Claim 10
Dependent Claim
18 words
The device of claim 6 wherein said elongate balloon in its uninflated state is folded within the housing.
Claim 11
Dependent Claim
21 words
The device of claim 6 wherein said elongate balloon in its uninflated state is longitudinally and coaxially folded within the housing.
Claim 12
Dependent Claim
18 words
The device of claim 6 wherein said elongate balloon in its uninflated state is folded in accordion folds.
Claim 13
Independent Claim
87 words
A device for separating a vessel in the body from surrounding connected tissue, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing, said elongate balloon in its uninflated state being folded, and said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape having inner and outer walls, said inner wall defining a lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 14
Independent Claim
87 words
A device for separating a vessel in the body from surrounding connected tissue, said device comprising: a housing having proximal and distal ends; and an elongate balloon disposed on said housing, said elongate balloon in its uninflated state being folded, and said elongate balloon in its inflated state being at least partially unfolded and forming a tubular shape having inner and outer walls, said inner wall defining a lumen, said lumen having open distal and proximal ends to allow insertion of a surgical device through said lumen.
Claim 15
Dependent Claim
15 words
The device of claim 11 wherein said elongate balloon is made from a nonelastic material.
Claim 16
Dependent Claim
19 words
The device of claim 11 wherein said elongate balloon in its uninflated state is folded within the housing member.
Claim 17
Dependent Claim
21 words
The device of claim 11 wherein said elongate balloon in its uninflated state is longitudinally and coaxially folded within the housing.
Claim 18
Dependent Claim
18 words
The device of claim 11 wherein said elongate balloon in its uninflated state is folded in accordion folds.
