Abstract
A multiple balloon catheter for use in a vessel of a patient and for use with an inflation/deflation device. A flexible elongate tubular member with proximal and distal extremities has a distal balloon mounted on the distal extremity of the flexible elongate tubular member. Coaxial inner and outer balloons are mounted on the distal extremity of the flexible elongate member proximal of the distal balloon. The flexible elongate tubular member has balloon inflation lumens therein in communication with the interiors of the distal balloon and the inner and outer coaxial balloons. A manifold is secured to the proximal extremity of the flexible elongate tubular member in communication with the inflation lumens and is adjusted to be coupled to the inflation/deflation device. Valves are carried by the inflation/deflation manifold for inflating the distal balloon in the inner and outer coaxial balloons one at a time or in unison without removal of the inflation/deflation device from the manifold.
