Abstract
According to the invention there is provided an intravascular catheter comprising an elongated flexible jacket having opposed proximal and distal ends and a central passageway extending between and interconnecting the ends. A rotating working head is located at the distal end of the jacket. A flexible drive cable extends through the passageway of the jacket, having a driving end operatively connected to the working head for rotating it, and a driven end operatively connected to a high-speed motor. The working head is rotatably mounted in a bearing sleeve which is further attached to the catheter jacket. The working head is actuated, by a actuator which adjust the a pair of tip portions from an at least initial retracted position with a first effective working diameter to an extended position with a second effective working diameter greater than the first effective diameter. Centrifugal forces generated by rotation of the cable cause the tip portions to assume the greater effective working diameter.
