Abstract:
1. A system for breaking up thrombi or plaque comprising: a generator with a grinder subgenerator and an ultrasonic subgenerator; a grinder handpiece connected in electrical communication with the grinder subgenerator, the grinder handpiece including a motor and a grinding tool connected mechanically to the motor, the rotational speed of the grinding tool being associated with electrical energy provided by the grinder subgenerator to the motor; an ultrasonic handpiece connected in electrical communication with the ultrasonic subgenerator, the ultrasonic handpiece including a transducer, a first wire guide distally extending from the transducer, and a vibrating tip having a larger diameter than the first wire guide, the vibrating tip being located distally of the transducer attached to a distal end of the first wire guide, the vibrating tip connected mechanically to the transducer via the wire guide, the amplitude of the vibrations at the vibrating tip being associated with electrical energy provided by the ultrasonic subgenerator to the transducer, the vibrating tip being configured to contact body tissue and to liquefy, dissolve, or break up the thrombi or plaque, the vibrating tip and the grinding tool extending in non-coaxial directions relative to each other; wherein the grinder handpiece includes a second wire guide with a lumen, one end of the second wire guide being connected to the grinder handpiece, the grinding tool being disposed at the other end and being connected to the motor through the lumen of the second wire guide.
