ABSTRACT:
An atherectomy catheter having ultrasound imaging capability provided by an acoustic transducer disposed within a catheter housing which includes a circular cutting edge for removal of stenotic tissue. Risk of induced emboli is reduced by arrangements of transducer and cutter maneuvering members which permit the cutting edge to remain shielded by the housing during catheter positioning and scanning. Both single and array transducers are employed in a variety of configurations.
