Abstract:
1. A treatment device, comprising: a first catheter and a second catheter, wherein the second catheter is at least partially disposed within the first catheter; at least a first pair of balloons connected to the first catheter closer to a distal end of the catheter than a proximal end of the catheter, the first pair of balloons including a first opening therebetween; at least a second pair of balloons spaced apart from the first pair of balloons and connected to the second catheter closer to the proximal end of the catheter than the first pair of balloons, the second pair of balloons including a second opening therebetween; at least one first lumen at least partially extending through the catheter, the first lumen being operatively connected to the first and second pair of balloons, wherein the at least one first lumen is configured to effect dilation and deflation the first and second pair of balloons; and at least one second lumen at least partially extending through the catheter, the second lumen being in communication with the first and second openings of the first pair of balloons and the second pair of balloons, wherein the second lumen is configured to deliver aspiration between the first pair and the second pair of balloons so as to create a sealed treatment region between a vessel wall and the first and second pair of balloons.
