Methods for preheating tissue for cosmetic treatment of the face and body
View Patent ↗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. Methods of lifting sagging tissue on a face and/or neck are described. Pretreatment with heat is provided in several embodiments.
1. A method of non-invasive skin rejuvenation, comprising:
providing a probe that delivers ultrasound energy;
wherein the probe is configured for placement on a skin surface over a region comprising a connective tissue;
delivering energy to the region for a pretreatment heating effect; and
delivering focused therapeutic ultrasound energy to the region with the probe,
wherein the focused therapeutic ultrasound energy thermally treats the connective tissue at a depth under the skin surface to rejuvenate skin.
2. The method of claim 1 , wherein delivering the focused therapeutic ultrasound energy comprises delivering ultrasound energy from a single therapy element in the probe.
3. The method of claim 1 , further comprising imaging the tissue under the skin surface.
4. The method of claim 1 , wherein the depth is up to 9 mm under the skin surface.
5. A method of rejuvenating skin, comprising:
providing an ultrasonic probe that emits ultrasound energy;
wherein the ultrasonic probe is configured for placement on a skin surface over a region comprising a subcutaneous connective tissue;
wherein the ultrasonic probe is configured for delivering diffuse ultrasound energy to the region for a heating effect; and
wherein, after the delivery of the diffuse ultrasound energy, the ultrasonic probe is configured for delivering focused therapeutic ultrasound energy to the region,
wherein the focused therapeutic ultrasound energy treats the subcutaneous connective tissue at a depth under the skin surface to rejuvenate the skin.
6. The method of claim 5 , wherein the ultrasonic probe further comprises an imaging element to image the region.
