Abstract
A balloon catheter is described having a reinforced, co-axial, duel lumen design. In some embodiments, the balloon catheter includes a purging mechanism designed to purge air from the balloon.
Claims20
A balloon catheter system, comprising:
- an outer tubular assembly comprising an inflation lumen;
- a balloon, wherein a proximal portion of the balloon is affixed to the outer tubular assembly;
- an inner tubular assembly, wherein a distal portion of the balloon is affixed to the inner tubular assembly;
- wherein the inner tubular assembly includes a purge port in fluid communication with an interior of the balloon, the purge port comprising a gas-permeable membrane that restricts passage of liquid through the membrane;
- wherein the distal portion of the balloon is bonded to the gas-permeable membrane;
- and
- a de-airing channel in fluid communication with the purge port through which gas expelled from the balloon may exit the balloon catheter system.

A balloon catheter system, comprising:
- an outer tubular assembly comprising an inflation lumen;
- a balloon, wherein a proximal portion of the balloon is affixed to the outer tubular assembly;
- wherein an inflation fluid is delivered to the balloon through the inflation lumen;
- an inner tubular assembly, wherein a distal portion of the balloon is affixed to the inner tubular assembly;
- wherein the inner tubular assembly includes a purge port in fluid communication with an interior of the balloon, the purge port comprising a gas-permeable membrane that restricts passage of liquid through the membrane;
- and
- a de-airing channel in fluid communication with the purge port and in fluid communication with a space external to the balloon catheter system, wherein the purge port and the de-airing channel project into a wall of the inner tubular assembly.
4 more elements
A balloon catheter system, comprising:
- an outer tubular assembly comprising an inflation lumen;
- an inflation means, wherein a proximal portion of the inflation means is affixed to the outer tubular assembly;
- an inner tubular assembly, wherein a distal portion of the inflation means is affixed to the inner tubular assembly;
- wherein the inner tubular assembly includes a purge port in fluid communication with an interior of the inflation means, the purge port comprising a gas-permeable membrane that restricts passage of liquid through the membrane;
- and
- a de-airing means in fluid communication with the purge port and in fluid communication with a space external to the balloon catheter system;
- a distal-non-inflatable portion of the inflation means bonded at a distal end of the inner tubular assembly and over the de-airing means.

A balloon catheter system, comprising:
- an outer tubular assembly comprising an inflation lumen;
- a balloon, wherein a proximal portion of the balloon is affixed to the outer tubular assembly;
- an inner tubular assembly, wherein a distal portion of the balloon is affixed to the inner tubular assembly;
- wherein the inner tubular assembly includes a purge port in fluid communication with an interior of the balloon, the purge port comprising a gas-permeable membrane that restricts passage of liquid through the membrane;
- wherein the membrane spans an entire distal section of the inner tubular assembly;
- and
- a de-airing channel in fluid communication with the purge port through which gas expelled from the balloon may exit the balloon catheter system.
