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, wherein the purge passage is 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 the exterior of the tubular member and a closed configuration to prevent movement of fluid through the purge passage;
- and,
- a first liner means for compressing the purge passage when the purge passage is in the closed configuration.

- a balloon attached to a distal portion of a tubular member, wherein the tubular member includes an inflation lumen in communication with the balloon;
- and
- a purge passage extending between an interior of the balloon and an exterior of the tubular member, the purge passage having a first open configuration to allow movement of fluid through the purge passage to the exterior of the tubular member and a second closed configuration to prevent movement of fluid through the purge passage;
- and,
- wherein at least a portion of a length of the purge passage is collapsible in response to a stimulus.
