1. A method of treating skin laxity, comprising:
- imaging a treatment area under a skin surface, the treatment area comprising a combination of a muscle tissue and any one or more of the group consisting of;
an epidermal tissue, a superficial dermal tissue, a mid-dermal tissue, a deep dermal tissue, and an adipose tissue;
delivering ultrasound energy with an ultrasound transducer through the skin surface to cause thermal lesions to the treatment area; and
using a motion mechanism to move the ultrasound transducer within a probe to form a plurality of thermal foci to create the lesions along a line in the treatment areawherein the ultrasound transducer is coupled to the motion mechanism within the probe,thereby treating skin laxity in the skin surface.

Abstract
A method and system for ultrasound treatment of skin laxity are provided. Methods and systems can include ultrasound imaging of the region of interest for localization of the treatment area, delivering ultrasound energy at a depth and pattern to achieve the desired therapeutic effects, and/or monitoring the treatment area to assess the results and/or provide feedback. The exemplary treatment method and system can be configured for producing arrays of sub-millimeter and larger zones of thermal ablation to treat the epidermal, superficial dermal, mid-dermal and deep dermal components of tissue.

12. A method of delivering ultrasound energy for reducing laxity in skin, comprising:
-
imaging a treatment area under a skin surface, the treatment area comprising a combination of a muscle tissue and any one or more of the group consisting of;
an epidermal tissue, a superficial dermal tissue, a mid-dermal tissue, a deep dermal tissue, and an adipose tissue;delivering ultrasound energy from an ultrasound source to a first target in the treatment area to create a thermal lesion; moving the ultrasound source with a motion mechanism, delivering ultrasound energy from the ultrasound source to a second target in the treatment area to create a second thermal lesion, thereby creating a plurality of thermal lesions below the skin surface, thereby shrinking a volume of tissue comprising the first target and the second target in the treatment area to rejuvenate the laxity in the skin surface. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for non-invasive treatment for skin laxity, the method comprising:
providing an ultrasound system comprising an ultrasound probe, a therapy transducer in the probe, and an imaging transducer, the ultrasound system configured for; (i) imaging, with the imaging transducer, a region of interest under a skin surface, wherein the region of interest comprises an adipose tissue and a muscle tissue; (ii) treating, with the therapy transducer, skin laxity in the skin surface, wherein the therapy transducer is configured to deliver ultrasound energy to cause thermal lesions in at least the adipose tissue and the muscle tissue in the region of interest; and (iii) moving the therapy transducer, with a motion mechanism, to form a plurality of the thermal lesions in at least the adipose tissue and the muscle tissue in the region of interest to reduce skin laxity in the skin surface. - View Dependent Claims (19, 20, 21, 22, 23, 24)
