Patent ID: 8048095

Claim:
An ultrasound assisted liquid blade cutting device comprising: a. an ultrasound generator; b. an ultrasound transducer producing ultrasonic energy within a housing; c. the ultrasound transducer in electrical communication with the ultrasound generator; d. a transducer tip connected to the ultrasound transducer, the transducer tip having a cavity within a region of the distal end of the tip having orthogonal dimensions no larger than the orthogonal dimensions of the proximal end of the tip and receiving a liquid through a supply tube; e. the liquid forming a spray within the cavity; f. the spray used as a coupling medium for the ultrasound energy; g. the cavity generating ultrasound energy; and h. the cavity directing the spray and the ultrasound energy to produce a liquid blade, the liquid blade being formed by a series of cutting foci along a line parallel to the longitudinal axis of the transducer tip distal end.
