摘要：
A balloon catheter (10) having a shaft (16), a balloon (14), and an external delivery tube (12) is disclosed. Methods of using the balloon catheter having an external delivery tube are also disclosed. 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 (100) is coupled with the catheter body. An agent delivery assembly (102) is coupled with the catheter body and the inflatable balloon assembly. The agent delivery assembly includes a delivery lumen (32) extending through the catheter body, and an agent delivery tube extending along an exterior balloon surface (64). The agent delivery tube includes at least one delivery orifice (70) directed outside of the exterior balloon surface. The agent delivery assembly is isolated from fluid communication with the inflatable balloon assembly.Cette invention concerne un cathéter à ballonnet (10) comportant une tige (16), un ballonnet (14) et un tube dadministration externe (12). Cette invention concerne des méthodes dutilisation dudit cathéter. Dans un exemple, le cathéter à ballonnet est un cathéter dadministration dagent comportant un corps situé entre une partie proximale et une partie distale. Un ensemble ballonnet gonflable (100) est couplé au corps. Un ensemble administration dagent (102) est couplé au corps et à lensemble ballonnet gonflable. Lensemble administration dagent comporte une lumière dadministration (32) traversant le corps du cathéter, et un tube dadministration dagent longeant la face extérieure du ballonnet (64). Le tube dadministration dagent comporte au moins un orifice dadministration (70) orienté hors de la face extérieure du ballonnet. Lensemble administration dagent est isolé de toute communication fluidique avec lensemble ballonnet gonflable.
