Abstract
Abstract A perfusion balloon catheter includes an inflatable balloon formed by a series of loops of a flexible, inflatable tube in a generally cooperative tubular shape. The loops are supported by a coiled support member and are locked within the coiled support member by a wire retainer. The cooperative tubular shape of the individual loops perform to provide an inflatable cooperative outer surface of the balloon and a perfusion passage within the balloon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A method for making a perfusion balloon catheter, the method comprising: inserting a length of uninflated flexible tube into an end of a coiled support member; threading the tube through a side of the coiled support member; repeatedly wrapping the tube around the coiled support member and a support mandril, which is positioned adjacent to the coiled support member, to create a series of cooperative, side-by-side loops of the tube; sealing a first end of the tube at a desired distance from a first loop of the tube; inserting a retainer through a length of the coiled support member and between a portion of the coiled support member and each tube loop; heating the tube and applying fluid pressure to a second end of the tube to inflate the loops; cooling the tube; removing the fluid pressure; removing the support mandril; and connecting the tube to a distal end of a catheter shaft.
Claim 2
Independent Claim
153 words
A method for making a perfusion balloon catheter, the method comprising: inserting a length of uninflated flexible tube into an end of a coiled support member; threading the tube through a side of the coiled support member; repeatedly wrapping the tube around the coiled support member and a support mandril, which is positioned adjacent to the coiled support member, to create a series of cooperative, side-by-side loops of the tube; sealing a first end of the tube at a desired distance from a first loop of the tube; inserting a retainer through a length of the coiled support member and between a portion of the coiled support member and each tube loop; heating the tube and applying fluid pressure to a second end of the tube to inflate the loops; cooling the tube; removing the fluid pressure; removing the support mandril; and connecting the tube to a distal end of a catheter shaft.
Claim 3
Dependent Claim
55 words
The method of claim 1 wherein connecting the tube to the distal end of the catheter shaft comprises: inserting the second end of the tube and a portion of the retainer into a lumen at the distal end of the shaft; and bonding the tube and the retainer to the distal end of the shaft.
Claim 4
Dependent Claim
50 words
The method of claim 2 wherein connecting the tube to the distal end of the catheter shaft further comprises: inserting a portion of the coiled support member into the lumen at the distal end of the shaft; and bonding the coiled support member to the distal end of the shaft.
Claim 5
Dependent Claim
17 words
The method of claim 1 and further comprising: connecting a guide wire support to the wire coil.
Claim 6
Dependent Claim
21 words
The method of claim 4 wherein the guide wire support is connected to a distal end of the coiled support member.
Claim 7
Dependent Claim
20 words
The method of claim 4 wherein the guide wire support includes a guide tube which defines a guide wire lumen.
Claim 8
Dependent Claim
15 words
The method of claim 6 wherein the guide tube extends through the coiled support member.
Claim 9
Dependent Claim
21 words
The method of claim 7 and further comprising: inserting the guide tube into the coiled support member after inserting the retainer.
Claim 10
Dependent Claim
31 words
The method of claim 7 and further comprising: inserting the guide tube into the coiled support member before repeatedly wrapping the tube around the coiled support member and the support mandril.
