Abstract
Front-end and side-on intravascular catheters are described that comprise an abrasive head contained substantially within a housing. Aspiration means and flushing means are connected to the region of grinding to remove dislodged debris. A preferred embodiment has the abrasive surface of a rotatable head comprised of diamond powder, fused silica, tungsten carbide, aluminum oxide, or boron nitride. Another preferred embodiment has an ultrasonic transducer affixed to the head to permit transluminal imaging of the site of occlusion.
