摘要：
A balloon catheter having a shaft, a balloon, and an external delivery tube, as well as methods of use thereof. In one example, the balloon catheter is an agent delivery catheter including a catheter body extending between catheter proximal and distal portions. An inflatable balloon assembly is coupled with the catheter body. An agent delivery assembly, which is coupled with the catheter body and the inflatable balloon assembly, includes a delivery lumen extending through the catheter body and an agent delivery tube extending along an exterior balloon surface. The agent delivery tube includes at least one delivery orifice directed outside of the exterior balloon surface. The agent delivery assembly is isolated from fluid communication with the inflatable balloon assembly.
