Abstract
Systems and methods for treating skin and subcutaneous tissue with energy such as ultrasound energy are disclosed. In various embodiments, ultrasound energy is applied at a region of interest to affect tissue by cutting, ablating, micro-ablating, coagulating, or otherwise affecting the subcutaneous tissue to conduct numerous procedures that are traditionally done invasively in a non-invasive manner. Lifting sagging tissue on a face, neck, and/or body are described. Treatment with heat is provided in several embodiments.
Claims19
A method of tightening skin tissue, comprising:
- placing an ultrasonic probe on a skin surface over a target tissue;
- directing therapeutic ultrasound energy from a piezoelectrically active transduction element of the ultrasonic probe, through the skin surface tissue to the target tissue comprising at least one of the group consisting of:
- a dermis tissue and a fascia tissue;
- and
- cooling an interface between the ultrasonic probe and the skin surface with a cooling system,
- thereby treating at least the fascia tissue in the target tissue at one or more depths under the skin surface to tighten the skin.
A method of non-invasive tissue treatment, comprising:
- acoustically coupling an ultrasound probe on a skin surface over a region comprising a target tissue comprising a fat tissue and a fascia tissue;
- delivering ultrasound energy from at least one piezoelectrically active transduction element to heat the target tissue at one or more depths under the skin surface to treat the at least the fascia tissue in the target tissue, and
- cooling an interface between the ultrasound probe and the skin surface with a cooling system.
A method of non-invasive skin rejuvenation, comprising:
- acoustically coupling an ultrasonic probe on a skin surface proximate a region comprising a target tissue comprising at least one of the group consisting of:
- a dermis tissue and a superficial muscular aponeurotic system (“SMAS”) tissue,
- delivering ultrasound energy with a frequency of 3 MHz to 100 MHz from the ultrasonic probe to the target tissue for a heating effect to treat at least the SMAS tissue in the target tissue at a depth under the skin surface to rejuvenate the skin, and
- cooling an interface between the ultrasonic probe and the skin surface with a cooling system.
