Abstract
Abstract A rapid exchange stent delivery balloon catheter which allows exchange from a balloon angioplasty catheter to a stent delivery catheter without the need to replace the angioplasty catheter wire guide with an exchange-length wire guide before exchanging the catheters. The stent delivery catheter of the present invention includes a relatively short wire guide shaft which is bonded to the catheter shaft only at a location distal to the inflation lumen.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
269 words
A method of making a rapid exchange stent delivery balloon catheter, comprising the steps of: a) providing a first length of first tubing having a first lumen, a proximal end and a distal end; b) closing the first tubing distal end; c) providing a first mold having interior dimensions substantially equal to desired balloon dimensions; d) placing a portion of the first tubing into the first mold; e) heating the portion of the first tubing in the first mold; f) pressurizing the first lumen such that the portion of the first tubing in the first mold expands to the interior dimensions of the first mold, thereby forming a balloon; g) cooling the portion of the first tubing in the first mold such that the portion of the first tubing in the first mold retains a shape of the interior of the first mold; h) removing the first tubing from the first mold; i) cutting the first tubing distal end at a point distal to a distal end of the balloon; j) providing a second length of second tubing having a second lumen, a proximal end and a distal end; k) inserting a mandrel into the second lumen at least adjacent the second tubing distal end; l) placing the first tubing distal end and the second tubing distal end adjacent one another in a second mold; and m) heating the first and second tubing distal ends until they bond together to form a catheter tip, thereby bonding the second tubing to the first tubing only at the first tubing distal end completely distal of the distal end of the balloon.
Claim 2
Independent Claim
269 words
A method of making a rapid exchange stent delivery balloon catheter, comprising the steps of: a) providing a first length of first tubing having a first lumen, a proximal end and a distal end; b) closing the first tubing distal end; c) providing a first mold having interior dimensions substantially equal to desired balloon dimensions; d) placing a portion of the first tubing into the first mold; e) heating the portion of the first tubing in the first mold; f) pressurizing the first lumen such that the portion of the first tubing in the first mold expands to the interior dimensions of the first mold, thereby forming a balloon; g) cooling the portion of the first tubing in the first mold such that the portion of the first tubing in the first mold retains a shape of the interior of the first mold; h) removing the first tubing from the first mold; i) cutting the first tubing distal end at a point distal to a distal end of the balloon; j) providing a second length of second tubing having a second lumen, a proximal end and a distal end; k) inserting a mandrel into the second lumen at least adjacent the second tubing distal end; l) placing the first tubing distal end and the second tubing distal end adjacent one another in a second mold; and m) heating the first and second tubing distal ends until they bond together to form a catheter tip, thereby bonding the second tubing to the first tubing only at the first tubing distal end completely distal of the distal end of the balloon.
Claim 3
Dependent Claim
51 words
The method of claim 1, further comprising the steps of: n) providing a stiffening wire having a proximal end and a distal end; and o) inserting the stiffening wire through the first lumen and through an interior of the balloon until the stiffening wire distal end extends into the catheter tip.
Claim 4
Dependent Claim
29 words
The method of claim 2, further comprising the steps of: p) cooling the catheter tip until the catheter tip solidifies; and q) removing the mandrel from the second lumen.
Claim 5
Dependent Claim
24 words
The method of claim 2, wherein step (n) further comprises providing a stainless steel stiffening wire having at least one radiopaque marker band thereon.
Claim 6
Dependent Claim
34 words
The method of claim 4, wherein step (o) further comprises inserting the stiffening wire until one of the at least one radiopaque marker bands is substantially aligned with the distal end of the balloon.
Claim 7
Dependent Claim
20 words
The method of claim 1, wherein step (a) further comprises providing a first length of tubing formed from cross-linked polyethylene.
Claim 8
Independent Claim
99 words
A method of making a rapid exchange stent delivery balloon catheter, comprising the steps of: a) providing a first length of first tubing having a first lumen, a proximal end and a distal end; b) forming a balloon having proximal and distal ends in the first tubing adjacent the first tubing distal end; c) providing a second length of second tubing having a second lumen, a proximal end and a distal end; d) connecting and bonding the second tubing to the first tubing only at the first tubing distal end completely distal of the distal end of the balloon.
Claim 9
Independent Claim
99 words
A method of making a rapid exchange stent delivery balloon catheter, comprising the steps of: a) providing a first length of first tubing having a first lumen, a proximal end and a distal end; b) forming a balloon having proximal and distal ends in the first tubing adjacent the first tubing distal end; c) providing a second length of second tubing having a second lumen, a proximal end and a distal end; d) connecting and bonding the second tubing to the first tubing only at the first tubing distal end completely distal of the distal end of the balloon.
Claim 10
Dependent Claim
123 words
The method of claim 7, wherein step (b) further comprises the steps of: b.1) closing the first tubing distal end; b.2) providing a first mold having interior dimensions substantially equal to desired balloon dimensions; b.3) placing a portion of the first tubing into the first mold; b.4) heating the portion of the first tubing in the first mold; b.5) pressurizing the first lumen such that the portion of the first tubing in the first mold expands to the interior dimensions of the first mold, thereby forming a balloon; and b.6) cooling the portion of the first tubing in the first mold such that the portion of the first tubing in the first mold retains a shape of the interior of the first mold.
Claim 11
Dependent Claim
31 words
The method of claim 7, further comprising the step of: e) inserting a mandrel into the second lumen at least adjacent the second tubing distal end prior to performing step (d).
Claim 12
Dependent Claim
68 words
The method of claim 7, wherein step (d) further comprises the steps of: d.1) inserting a mandrel into the second lumen at least adjacent the second tubing distal end; d.2) placing the first tubing distal end and the second tubing distal end adjacent one another in a second mold; and d.3) heating the first and second tubing distal ends until they bond together to form a catheter tip.
