Abstract

An agent delivery catheter having two or more axially spaced balloons and an inflation bridge providing fluid communication between the two balloons. The catheter generally has a proximal balloon, a distal balloon, and a tube defining an inflation bridge lumen which is located in part within the inflatable interiors of the balloons, and which extends therebetween, and which has a proximal port within the proximal balloon interior and a distal port within the distal balloon interior to thereby provide for inflation of the distal balloon by placing the distal balloon interior in fluid communication with the proximal balloon interior of the shaft.
