Abstract
A surgical device for cleaning and removing obstructing material from within a vascular conduit or other bodily passageway. The device comprises a balloon catheter having an independently operable outer woven sleeve having a plurality of mesh openings. The woven sleeve surrounds the radially expandable and contractible balloon. In one embodiment, the outer woven sleeve is configured into a predetermined shape through manipulation of the catheter and used to maintain the inflated balloon within that predetermined configuration. In another embodiment, the woven sleeve is radially expanded by the inflated balloon such that the woven mesh is driven into the vascular conduit. The woven sleeve may be used to abrade the surface of the vascular conduit and increase the flow passage or alternatively as traction for various other surgical procedures within the vascular conduit.
