Abstract
Abstract An over-the-wire balloon dilatation catheter of the short guide wire lumen type has a stainless steel hypotube catheter shaft section, a distal plastic shaft section attached to the hypotube and a balloon connected to the distal plastic shaft section. A relatively short guide wire lumen extends throughout the length of the balloon. The distal shaft section includes a reinforcing and kink-resistant transition member extending throughout the length of the distal shaft section. The transition member allows the proximal guide wire lumen aperture to be placed distally from the distal end of the hypotube. This configuration permits the length of the guide wire lumen to be minimized.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
A balloon catheter, comprising: a tubular shaft having a proximal end and a distal end, the shaft including a proximal portion and a more flexible portion, and an inflation lumen extending therethrough; a balloon being connected to the distal end of the shaft; and a guidewire tube extending through the balloon and having a proximal end and a distal end, the proximal end of the guidewire tube being disposed proximate the distal end and external the distal end of the shaft, wherein the distal end of the shaft surrounds at least in part the proximal end of the guidewire tube such that the inflation lumen at least in part surrounds the proximal end of the guidewire tube; wherein the distal end of the shaft defines a generally crescent shaped inflation lumen which at least in part surrounds the proximal end of the guidewire tube; and a strain relief member extending from the proximal portion of the shaft to the more flexible distal portion of the shaft, the strain relief member being fixedly connected to the shaft; wherein the strain relief member includes an elongate core wire extending distally to the balloon.
Claim 2
Dependent Claim
191 words
A balloon catheter, comprising: a tubular shaft having a proximal end and a distal end, the shaft including a proximal portion and a more flexible portion, and an inflation lumen extending therethrough; a balloon being connected to the distal end of the shaft; and a guidewire tube extending through the balloon and having a proximal end and a distal end, the proximal end of the guidewire tube being disposed proximate the distal end and external the distal end of the shaft, wherein the distal end of the shaft surrounds at least in part the proximal end of the guidewire tube such that the inflation lumen at least in part surrounds the proximal end of the guidewire tube; wherein the distal end of the shaft defines a generally crescent shaped inflation lumen which at least in part surrounds the proximal end of the guidewire tube; and a strain relief member extending from the proximal portion of the shaft to the more flexible distal portion of the shaft, the strain relief member being fixedly connected to the shaft; wherein the strain relief member includes an elongate core wire extending distally to the balloon.
Claim 3
Dependent Claim
18 words
The catheter in accordance with claim 1, wherein the elongate core wire is connected to the guidewire tube.
Claim 4
Dependent Claim
142 words
A balloon catheter, comprising: a tubular shaft having a proximal end and a distal end, the shaft including a proximal portion and a more flexible portion, and an inflation lumen extending therethrough; a balloon being connected to the distal end of the shaft; and a guidewire tube extending through the balloon and having a proximal end and a distal end, the proximal end of the guidewire tube being disposed proximate the distal end and external the distal end of the shaft, wherein the distal end of the shaft surrounds at least in part the proximal end of the guidewire tube such that the inflation lumen at least in part surrounds the proximal end of the guidewire tube; and an elongate core wire disposed in the inflation lumen and extending distally to the balloon, the core wire being fixedly connected to the shaft.
Claim 5
Dependent Claim
142 words
A balloon catheter, comprising: a tubular shaft having a proximal end and a distal end, the shaft including a proximal portion and a more flexible portion, and an inflation lumen extending therethrough; a balloon being connected to the distal end of the shaft; and a guidewire tube extending through the balloon and having a proximal end and a distal end, the proximal end of the guidewire tube being disposed proximate the distal end and external the distal end of the shaft, wherein the distal end of the shaft surrounds at least in part the proximal end of the guidewire tube such that the inflation lumen at least in part surrounds the proximal end of the guidewire tube; and an elongate core wire disposed in the inflation lumen and extending distally to the balloon, the core wire being fixedly connected to the shaft.
Claim 6
Dependent Claim
39 words
The catheter in accordance with claim 3, wherein the elongate core wire is in contact with at least one side of the inflation lumen where the distal end of the shaft at least in part surrounds the guidewire tube.
