Abstract:
1. An ultrasonic system for destroying undesired tissue at an internal site within a body of a patient, comprising: (a) a probe that is sized to be inserted within a body of a patient; (b) an ultrasonic transducer mounted proximate a distal end of the probe, said ultrasonic transducer being adapted to couple to a power supply to selectively energize the ultrasonic transducer so that it produces a focused beam of high intensity ultrasonic energy configured to heat tissue between the transducer and a focal point based on a combination of at least two of an f-number, an intensity, a time, and a direction of the beam of high intensity ultrasonic energy and to treat the undesired tissue at the focal point, wherein said high intensity ultrasonic energy is configured to heat tissue between the transducer and focal point to a level sufficient to cause a lesion to form between the focal point and the ultrasonic transducer and to not cause a lesion to form substantially beyond the focal point; and (c) an ultrasound transmissive interface that is coupled to the distal end of the probe, said ultrasound transmissive interface being disposed and adapted to transmit the high intensity ultrasonic energy produced by the ultrasonic transducer into a target, said high intensity ultrasonic energy increasing a temperature of the undesired tissue.
