Methods for noninvasive skin tightening
First Claim
1. A method for tissue shrinkage, the method comprising:
- providing an ultrasound therapy transducer for treating a region of interest,wherein the region of interest comprises collagen fibers below a skin surface; and
transmitting ultrasound energy from the ultrasound therapy transducer into the region of interest at a frequency of 4 MHz to 15 MHz, therebyheating the collagen fibers and a muscular fascia tissue in the region of interest to cause shrinkage of the collagen fibers for tightening of the skin surface.

Abstract
A method and system for noninvasive face lifts and deep tissue tightening are disclosed. An exemplary method and treatment system are configured for the imaging, monitoring, and thermal injury to treat the SMAS region. In accordance with an exemplary embodiment, the exemplary method and system are configured for treating the SMAS region by first, imaging of the region of interest for localization of the treatment area and surrounding structures, second, delivery of ultrasound energy at a depth, distribution, timing, and energy level to achieve the desired therapeutic effect, and third to monitor the treatment area before, during, and after therapy to plan and assess the results and/or provide feedback.

11. A method for tissue shrinkage, the method comprising:
-
providing an ultrasound imaging transducer for imaging a region of interest under a skin surface; wherein the region of interest comprises collagen fibers; providing an ultrasound therapy transducer for delivering therapeutic ultrasound energy to the region of interest to heat the collagen fibers and a muscle tissue with the therapeutic ultrasound energy at a temperature sufficient to shrink the collagen fibers, thereby tightening the skin surface; and wherein the imaging transducer and the therapy transducer are co-housed within a single probe. - View Dependent Claims (12, 13, 14)

15. A method for tissue shrinkage, the method comprising:
-
providing an ultrasound therapy transducer for treating a region of interest, wherein the region of interest comprises collagen fibers below a skin surface; and wherein ultrasound energy is transmitted from the ultrasound transducer into the region of interest, thereby heating the collagen fibers and a superficial muscular aponeurosis system (SMAS) tissue in the region of interest to cause shrinkage of the collagen fibers for tightening of the skin surface. - View Dependent Claims (16, 17, 18, 19)
