Abstract
A balloon catheter is described, having a reinforced, co-axial, duel 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.
Claims14
A balloon catheter comprising:
- a balloon attached to a distal portion of a tubular member;
- the tubular member having an inflation lumen in communication with the balloon;
- an inner guidewire tube having an inner lumen that accommodates a guidewire which passes through and extends distally beyond the inner lumen;
- and,
- a purge passage extending between an interior of the balloon and an exterior of the balloon catheter;
- wherein a first interior surface of the purge passage is a distal uninflatable portion of the interior of the balloon and a second interior surface of the purge passage is a swellable material surface;
- the purge passage having a first open configuration to allow movement of fluid through the purge passage to an exterior of the balloon catheter;
- and a second closed configuration to prevent movement of fluid through the purge passage.
