ABSTRACT:
A method and device for removal of intraluminal occlusions which includes a catheter having a cutting head in a distal end thereof. The cutting head undergoes a simultaneous longitudinal and rotational movement by means of fluid pressure applied to a distal piston to which the cutting head is attached, The proximal end of the catheter includes a reciprocating pump which applies the fluid pressure to the distal piston. The cutting head is retractable to a sheathed or retracted position during insertion and movement in a patient. Material removed by the cutting head can either be collected in a chamber located between the distal piston and the cutting head or aspirated through the proximal end of the catheter.
