System and method for noninvasive skin tightening
First Claim
1. A method for tissue shrinkage, the method comprising:
- providing an ultrasound probe comprising a housing and a piezoelectric therapy transducer for treating a region of interest,wherein the piezoelectric therapy transducer is housed within the housing,wherein the region of interest comprises a collagen fiber and a muscle tissue below a skin surface; and
focusing ultrasound energy from the ultrasound therapy transducer into the region of interest at a frequency of 4 MHz to 15 MHz,thereby heating the collagen fiber and the muscle tissue in the region of interest to cause shrinkage of the collagen fiber 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.

12. 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 a plurality of collagen fibers in a muscular fascia; providing a piezoelectric ultrasound therapy transducer for delivering therapeutic ultrasound energy to a region of interest under a skin surface to heat the plurality of collagen fibers in the muscular fascia with the therapeutic ultrasound energy at a temperature sufficient to shrink the plurality of collagen fibers in the muscular fascia, thereby tightening the skin surface; and wherein the imaging transducer and the piezoelectric therapy transducer are co-housed within a single ultrasound probe. - View Dependent Claims (13, 14, 15)

16. A method for shrinking skin tissue, the method comprising:
-
providing an ultrasound probe comprising a housing and a piezoelectric ultrasound therapy transducer for treating a region of interest, wherein the region of interest comprises collagen below a skin surface; and wherein the piezoelectric ultrasound therapy transducer comprises one of the group consisting of a spherical focus and a cylindrical focus, wherein ultrasound energy is transmitted from the ultrasound transducer into the region of interest, thereby heating the collagen in a superficial muscular aponeurosis system (SMAS) tissue in the region of interest to cause shrinkage of the collagen for tightening of the skin surface. - View Dependent Claims (17, 18, 19, 20)
