Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 157 words
A balloon catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of said inner tube disposed within the outer tube and a distal portion of said inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the proximal portion of the inner tube having an inner diameter in the range of 0.020 inches (0.51 mm) to about 0.035 inches(0.89 mm) and a wall thickness in the range of 0.0005 inches(0.0125 mm) to about 0.008 inches (0.20 mm) and wherein the distal portion of the inner tube having an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube and wherein the tip includes a one-way valve.
Claim 2
Dependent Claim 157 words
A balloon catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of said inner tube disposed within the outer tube and a distal portion of said inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the proximal portion of the inner tube having an inner diameter in the range of 0.020 inches (0.51 mm) to about 0.035 inches(0.89 mm) and a wall thickness in the range of 0.0005 inches(0.0125 mm) to about 0.008 inches (0.20 mm) and wherein the distal portion of the inner tube having an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube and wherein the tip includes a one-way valve.
Claim 3
Independent Claim 161 words
A method for inserting a balloon catheter said catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of the inner tube being disposed within the outer tube and a distal portion of the inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the distal portion of the inner tube has an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube, comprising the steps of: (a) advancing the catheter into a patient; and (b)generating a vacuum in the inner tube, said vacuum being of sufficient magnitude to cause the proximal portion of the inner tube but not the distal portion of the inner tube to at least partially collapse.
Claim 4
Independent Claim 161 words
A method for inserting a balloon catheter said catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of the inner tube being disposed within the outer tube and a distal portion of the inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the distal portion of the inner tube has an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube, comprising the steps of: (a) advancing the catheter into a patient; and (b)generating a vacuum in the inner tube, said vacuum being of sufficient magnitude to cause the proximal portion of the inner tube but not the distal portion of the inner tube to at least partially collapse.
Claim 5
Independent Claim 169 words
A method for inserting a balloon catheter said catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of a said inner tube being disposed between an outer surface and an inner surface of outer tube and a distal portion of said inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the distal portion of the inner tube has an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube, comprising the steps of: (a) advancing the catheter into a patient; and (b)generating a vacuum in the inner tube, said vacuum being of sufficient magnitude to cause the proximal portion of the inner tube but not the distal portion of the inner tube to at least partially collapse.
Claim 6
Independent Claim 169 words
A method for inserting a balloon catheter said catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of a said inner tube being disposed between an outer surface and an inner surface of outer tube and a distal portion of said inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the distal portion of the inner tube has an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube, comprising the steps of: (a) advancing the catheter into a patient; and (b)generating a vacuum in the inner tube, said vacuum being of sufficient magnitude to cause the proximal portion of the inner tube but not the distal portion of the inner tube to at least partially collapse.
Claim 7
Dependent Claim 36 words
The methods as claimed in claim 2 or 3 wherein a one-way valve is connected to the proximal portion of the inner tube and wherein the vacuum is generated by withdrawing gas across said one-way valve.
Claim 8
Dependent Claim 44 words
The methods as claimed in claim 2 or 3 wherein a one-way valve is connected to the proximal portion of the inner tube and wherein the vacuum is generated by withdrawing gas across said one-way valve and wherein the tip includes a one-way valve.
Claim 9
Dependent Claim 94 words
The methods as claimed in claim 2 or 3 wherein the proximal portion of the inner tube has an inner diameter in the range of 0.020 inches (0.51 mm) to 0.035 inches(0.89 mm) and a wall thickness in the range of 0.0005 inches(0.0125 mm) to 0.008 inches (0.20 mm) and wherein the distal portion of the inner tube has an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube.
Claim 10
Dependent Claim 162 words
A balloon catheter comprising an outer tube, a balloon, a tip and an inner tube, a proximal portion of said inner tube disposed between an outer surface and an inner surface of outer tube and a distal portion of said inner tube extending beyond a distal end of the outer tube, the tip, a distal end of the inner tube, and a distal end of the balloon membrane are connected, the proximal portion of the inner tube having an inner diameter in the range of 0.020 inches (0.51 mm) to 0.035 inches(0.89 mm) and a wall thickness in the range of 0.0005 inches(0.0125 mm) to 0.008 inches (0.20 mm) and wherein the distal portion of the inner tube having an inner diameter the same as that of the proximal portion of the inner tube and a wall thickness of at least 0.001 inches greater than that of the proximal portion of the inner tube and wherein the tip includes a one-way valve.
