1. A method of treating the skin, the method comprising:
- using an ultrasound probe to deliver ultrasound energy from a therapy element housed within the ultrasound probe to a region of interest at a depth under a skin surface,wherein the region of interest comprises a superficial muscular aponeurosis system (SMAS) tissue and at least one of a muscle, an adipose tissue, and a dermis tissue, andmoving the therapy element within the ultrasound probe for creating thermal foci along a line at the depth under the skin surface,wherein the creation of the thermal foci causes shrinkage of a plurality of collagen fibers in the SMAS for tightening of the skin surface.

Abstract
Systems and methods for noninvasive tissue tightening are disclosed. Thermal treatment of tissues such as superficial muscular aponeurosis system (SMAS) tissue, muscle, adipose tissue, dermal tissue, and combinations thereof are described. In one aspect, a system is configured for treating tissue through delivery of ultrasound energy at a depth, distribution, temperature, and energy level to achieve a desired cosmetic effect.

7. A method of treating the skin, the method comprising:
-
using an ultrasound probe to deliver ultrasound energy from a therapy element housed within the ultrasound probe to a region of interest at a depth under a skin surface, wherein the region of interest comprises a superficial muscular aponeurosis system (SMAS) tissue and at least two of a dermis, a muscle, and an adipose tissue, and moving the therapy element within the ultrasound probe for creating thermal foci along a line at the depth under the skin surface, wherein the creation of the thermal foci causes shrinkage of a plurality of collagen fibers in the SMAS for tightening of the skin surface. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for tissue shrinkage, the method comprising:
-
providing an ultrasound system comprising an ultrasound probe, an ultrasound therapy element housed within the probe, and an imaging element, the ultrasound system configured for; (i) imaging, with the imaging element, a region of interest under the skin surface, wherein the region of interest comprises a tissue; (ii) treating, with the therapy element, the tissue, wherein the tissue comprises a superficial muscular aponeurosis system (SMAS) tissue and at least one of a muscle, an adipose tissue, and a dermis tissue, wherein the therapy element is configured for delivery of energy at a temperature sufficient to cause shrinkage of a plurality of collagen fibers in the SMAS at a depth under the skin surface; and (iii) moving the therapy element, with a motion mechanism, to form a plurality of thermal foci at the depth to cause the shrinkage. - View Dependent Claims (14, 15, 16, 17, 18)
