SYSTEM AND METHOD FOR DELIVERING ENERGY TO TISSUE
First Claim
Patent Images
1. An ultrasound based device for non-invasively treating tissue below the skin surface, said device comprising:
- a handpiece ergonomically shaped to fit in an operator'"'"'s hand;
a transducer assembly near a distal end of the handpiece, the transducer assembly adapted to deliver ultrasound energy to the tissue;
a cooling assembly for selectively cooling the tissue surface, the cooling assembly coupled with the handpiece; and
a controller operably connected to the ultrasound energy source,wherein the controller and the transducer assembly are configured to treat tissue below the skin surface as the handpiece is positioned adjacent the skin surface, thereby heating a treatment zone below the skin surface without thermally damaging tissue that surrounds the treatment zone.

Abstract
Systems and methods for noninvasive skin treatment and deep tissue tightening are disclosed. An exemplary method and treatment system are configured for controlled thermal energy delivery to treat subdermal regions of the skin. First, specific control parameters such as power, skin temperature, and ultrasound frequency are chosen so as to provide localized delivery of ultrasound to a region of interest. Then, ultrasound energy is delivered at a frequency, depth, distribution, timing, and energy density to achieve the desired therapeutic effect.

34. A method of non-invasively treating tissue below a skin surface, said method comprising:
-
positioning an ultrasound based treatment device adjacent the skin surface, the treatment device comprising a cooling assembly and a transducer assembly; cooling the skin surface as the treatment device is disposed adjacent the skin surface; and delivering ultrasound energy to a treatment zone below the skin without direct contact between the transducer assembly and the skin surface, thereby heating the treatment zone without thermally damaging tissue surrounding the treatment zone. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
