Tandem balloon catheter

摘要: A balloon catheter comprises a shaft and plurality of lumens, having pair spaced, inflatable balloons carried on the to define an interballoon space between balloons. Each are connected separate inflation lumen permit deflation. fluid flow extends through communicates with space. Preferably, perfusion distal end shunting blood past inflated The spaced made elastomeric material, capable being diameter greater than their length. may be used by inflating first block vessel. One then adds therapeutic agent vessel at position one side in catheter. inflates second isolate medication two balloons, while avoiding undue pressure increase
