Non-invasive ultrasonic body contouring
First Claim
1. An apparatus for lysing adipose tissue, the apparatus comprising:
- a power source and modulator assembly configured to supply modulated electrical power;
an ultrasonic therapeutic transducer connected to said power source and modulator assembly and configured to convert the modulated electrical power to therapeutic ultrasonic energy directed at a target volume in a region of a body containing adipose and non-adipose tissue, so as to selectively lyse adipose tissue and not lyse non-adipose tissue which receives the therapeutic ultrasonic energy;
an ultrasonic imaging sub-system configured to identify changes in the target volume resulting from the therapeutic ultrasonic energy; and
a lipolysis control computer configured to control said power source and modulator assembly based on the changes identified by said ultrasonic imaging sub-system.

Abstract
An apparatus for lysing adipose tissue, the apparatus comprising a power source and a modulator assembly configured to supply modulated electrical power; an ultrasonic therapeutic transducer connected to the power source and modulator assembly and configured to convert the modulated electrical power to ultrasonic energy directed at a target volume in a region of a body containing adipose and non-adipose tissue, so as to selective generally lyse the adipose tissue and generally not lyse the non-adipose tissues; an ultrasonic imaging sub-system configured to identify changes in the target volume resulting from the ultrasonic energy; and a lipolysis control computer configured to control the power source and modulator assembly based on the changes identified by the ultrasonic imaging sub-system.

8. A method for selectively lysing adipose tissue, the method comprising:
-
generating a time-varying electrical signal having a time-separated series at a duty cycle of between 1;
2 to 1;
50, of high amplitude portions each corresponding to a cavitation period and each comprising multiple pulses;converting the electrical signal to therapeutic ultrasonic energy; and directing the therapeutic ultrasonic energy towards a target volume in a region of a body containing adipose and non-adipose tissue, thereby inducing selective cavitation in adipose tissue while not lysing non-adipose tissue which receives the therapeutic ultrasonic energy. - View Dependent Claims (9, 10, 11)

12. An automatically-positionable adipose tissue lysis apparatus, comprising:
-
a therapeutic ultrasonic transducer secured to a three-dimensional positioning assembly, said therapeutic ultrasonic transducer being configured to direct therapeutic ultrasonic energy at a target volume in a region of a body containing adipose and non-adipose tissue, so as to selectively lyse adipose tissue and not lyse non-adipose tissue which receives the therapeutic ultrasonic energy; a lipolysis control computer having a video camera connected thereto, said video camera being configured to externally image a portion of the body, and said lipolysis control computer being configured to detect indications on the imaged portion of the body; and a positioning control unit configured to control said three-dimensional positioning assembly so as to automatically position said ultrasonic transducer based on the detected indications. - View Dependent Claims (13, 14, 15, 16, 17, 18)
