Apertured multilayer balloon catheter system

Abstract

An apertured balloon catheter consisting of 3 segments: a proximal segment, a central segment and a distal segment. The proximal and distal segments have two layers, and the central segment has three layers. Each layer of the proximal, distal segment, and first two layers of the central segment are tethered at several points forming a space therebetween, which is selectively filled with a fluid by a conduit to expand the apertured balloon catheter. The third layer of the central segment forms a second space with the second central layer and is selectively filled by a separate conduit to expand against the vessel wall. The proximal balloon segment and the distal balloon segment have apertures within the tether points that communicate with the lumen of the blood vessel within the inflated balloon chamber. The size of the apertures is set to capture blood debris flowing through the apertured balloon catheter.
