Abstract
A system and method removes material from the wall of a passage, such as a vein or artery, in a patient's body with a series of bristles that are rotated. The bristles are part of a sweep catheter having a proximal end and a distal end with a tip thereon. Bristles next to the tip extend out from the distal end a shorter distance than the bristles further from the tip. The bristles, which have smaller bristles or sub-bristles thereon, are inclined away from the tip as they extend out from the distal end of the sweep catheter. The bristles push removed materials away from the tip and towards a suction channel of a guide catheter whereby the materials are removed.
