Abstract
A system for treating fat tissue, including: an ultrasound applicator, including: two or more ultrasound transducers configured to generate and direct ultrasonic waves to a selected tissue volume including fat tissue; a control unit, including: a control circuitry electrically connected to the two or more ultrasound transducers, wherein the control circuitry is configured to activate the two or more ultrasound transducers to heat the selected tissue volume.
Claims20
A system for fat tissue treatment, the system comprising:
- a plurality of piezoelectric (PZT) plates configured to generate ultrasound waves;
- a plurality of electrical connections associated with each of plurality of PZT plates, wherein the plurality of PZT plates and the plurality of electrical connections form a plurality of ultrasound transducers;
- one or more joints interconnecting the plurality of ultrasound transducers side-by-side in a linear arrangement to allow relative movement of at least some of the plurality of ultrasound transducers to conform to a contour of a treatment region, the treatment region including at least one of an abdomen, a thigh, or a buttocks;
- a strap configured to fasten the plurality of ultrasound transducers to the treatment region, such that the strap and the ultrasound transducers form a belt-shaped ultrasound applicator;
- and
- electrical circuitry configured to cause controlled emission of ultrasonic waves via the belt-shaped ultrasound applicator with intensity values in a range of 5-90 W/cm2 and frequency values in a range of 1-7 MHz to deliver ultrasonic energy to fat tissue at a depth of 2-20 mm beneath a skin surface of the treatment region to thereby heat the fat tissue to a temperature between 45° C. and 85° C.
A method for fat tissue treatment, the method comprising:
- placing a plurality of interconnected ultrasound transducers in a side-by-side linear arrangement on a non-flat tissue surface of epidermis, the non-flat tissue surface being associated with at least one of an abdomen, a thigh, or a buttocks, wherein each of the plurality of ultrasound transducers include at least one piezoelectric (PZT) plate, and wherein the plurality of ultrasound transducers are connected in series in a manner permitting the linear arrangement to flex in accordance with a contour of the non-flat tissue surface;
- fastening the plurality of ultrasound transducers to the non-fat tissue surface with a strap, such that the strap and the ultrasound transducers form a belt;
- and
- causing controlled emission of ultrasonic waves via the plurality of PZT plates with intensity values in a range of 5-90 W/cm2 and frequency values in a range of 1-7 MHz to deliver ultrasonic energy to fat tissue at a depth of 2-20 mm beneath a skin surface of the treatment region to thereby heat the fat tissue to a temperature between 45° C. and 85° C.
A non-transitory computer readable medium containing instructions that when executed by at least one processor cause the at least one processor to perform operations for fat tissue treatment, the operations comprising:
- activating a plurality of piezoelectric (PZT) plates associated with a plurality of electrical connections, wherein the plurality of PZT plates and the plurality of electrical connections form a plurality of ultrasound transducers flexibly connected side-by-side in a linear arrangement to allow relative movement of at least some of the plurality of ultrasound transducers to conform to a contour of a treatment region, the treatment region including at least one of an abdomen, a thigh, or a buttocks;
- and
- causing controlled emission of ultrasonic waves via the plurality of PZT plates with intensity values in a range of 5-90 W/cm2 and frequency values in a range of 1-7 MHz to deliver ultrasonic energy to fat tissue at a depth of 2-20 mm beneath a skin surface of the treatment region while at least some of the plurality of ultrasound transducers conform to the contour of the treatment region, to thereby heat the fat tissue to a temperature between 45° C. and 85° C.
