1. An ultrasonic medical device for treating tissue comprising:
- an ultrasonic probe having a proximal end, a distal end and a longitudinal axis between the proximal end and the distal end; and
a diameter of the ultrasonic probe that is tapered from the proximal end of the ultrasonic probe to the distal end of the ultrasonic probe, wherein the ultrasonic probe operates in a transverse mode of vibration with a transverse ultrasonic vibration along at least a portion of the longitudinal axis of the ultrasonic probe that produces a plurality of transverse vibration anti-nodes along at least a portion of the longitudinal axis of the ultrasonic probe.

Abstract
A method for destructing, reducing or removing mammalian tissue with an ultrasonic device is disclosed, comprising contacting the tissue with a transverse mode ultrasonic probe, and transmitting ultrasonic energy to the probe, until the tissue is fragmented by emulsification. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion and in combination with an imaging device to effect remodeling of human tissue in medical and cosmetic surgical procedures.

15. An ultrasonic medical device comprising:
-
a probe having a diameter that is tapered from a proximal end of the probe to a distal end of the probe; and
a longitudinal axis of the probe located between the proximal end and the distal end of the probe, wherein the probe is vibrated in a direction transverse to the longitudinal axis of the probe, creating a plurality of transverse vibration anti-nodes along at least a portion of the longitudinal axis of the probe and generating cavitation along at least a portion of the longitudinal axis of the probe to treat a tissue. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of remodeling a tissue comprising:
-
providing a flexible probe having a proximal end, a distal end and a longitudinal axis between the proximal end and the distal end;
moving the flexible probe to engage the tissue;
activating an ultrasonic vibration generator to produce a transverse ultrasonic vibration along at least a portion of a longitudinal axis of the flexible probe; and
sweeping the flexible probe through the tissue to remove the tissue in areas adjacent to a plurality of transverse vibration anti-nodes generated along at least a portion of the longitudinal axis of the flexible probe. - View Dependent Claims (23, 24, 25, 26, 27)
