Abstract
A balloon catheter is described, having a reinforced, co-axial, dual lumen design. At least one of the lumens is formed of a multilayer, tubular element in which one of the layers functions, in part, to provide radial reinforcement to the tubular element.
Claims20
A balloon catheter, comprising:
- a balloon attached to a distal portion of a tubular member, wherein the tubular member includes an inflation lumen in communication with the balloon;
- a purge passage extending between an interior of the balloon and an exterior of the tubular member;
- and
- a first liner connected to the purge passage;
- the purge passage having an open configuration to allow movement of fluid through the purge passage to the exterior of the tubular member and a closed configuration to prevent movement of fluid through the purge passage;
- and,
- wherein, in an inflated configuration, the first liner expands so as to obstruct at least a portion of the purge passage into the closed configuration without the first liner being exposed to an inflation liquid.

A balloon catheter, comprising:
- a balloon attached to a distal portion of a tubular member, wherein the tubular member includes an inflation lumen in communication with the balloon;
- a purge passage extending between an interior of the balloon and an exterior of the tubular member;
- and
- a first liner connected to a first side of the purge passage;
- a second liner connected to the purge passage, wherein the first liner is positioned at a first radial position along a circumference of the purge passage, wherein the second liner is positioned at a second radial position along the circumference of the purge passage, and wherein the first radial position is opposite to the second radial position;
- the purge passage having an open configuration to allow movement of fluid through the purge passage to the exterior of the tubular member and a closed configuration to prevent movement of fluid through the purge passage;
- and,
- wherein the first liner and the second liner obstruct the purge passage when the purge passage is in the closed configuration, wherein at least a portion of the purge passage is sealed when in the closed configuration.
5 more elements
A balloon catheter, comprising:
- a balloon attached to a distal portion of a tubular member, wherein the tubular member includes an inflation lumen in communication with the balloon;
- a purge passage incorporated into a wall of a distal portion of the balloon, the purge passage having an open configuration to allow movement of fluid through the purge passage to an exterior of the tubular member and a closed configuration to prevent movement of fluid through the purge passage;
- and,
- a first liner means for obstructing the purge passage when the purge passage is in the closed configuration;
- and,
- wherein, in an inflated configuration, the first liner means expands so as to obstruct at least a portion of the purge passage into the closed configuration without the first liner means being exposed to an inflation liquid.
