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. Another preferred embodiment has an ultrasonic transducer affixed to the head to permit transluminal imaging of the site of occlusion.
