ABSTRACT:
An apparatus for the removal of build-up about an implanted catheter having an interior surface, an exterior surface and an open free end positioned within an individual's vascular system. The apparatus includes a delivery assembly storing a stripping coil. The delivery assembly includes a guide structure for guiding the stripping coil through the catheter to the free end of the catheter. The stripping coil is formed of a shape memory or super-elastic material, wherein the stripping coil is preformed to assume a shape wrapping about the outer surface of the catheter in a manner providing for the stripping of build-up from the outer surface of the catheter when the stripping coil is moved relative to the catheter.
