Abstract
Front-end and side-on intravascular catheters are described that comprise an abrasive head contained substantially within a housing.

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.
