1. An ultrasound device for treatment of skin laxity, the device comprising:
- an ultrasound probe comprising a housing, wherein inside the housing comprises a motion mechanism and an ultrasound transducer,wherein the ultrasound transducer comprises a therapy component,wherein the therapy component comprises;
a single active focused piezoelectric ultrasound therapy element,wherein the piezoelectric ultrasound therapy element is configured to provide a single mechanical focus,wherein the single mechanical focus is configured to provide ultrasound therapy energy in a form of a single thermal focus in a tissue at a depth below a skin surface,wherein the depth is a single, fixed depth below the skin surface to treat the tissue,wherein the tissue comprises a combination of any of the group consisting of;
an epidermal tissue, a superficial dermal tissue, a mid-dermal tissue, a deep dermal tissue, a muscle tissue, and an adipose tissue,wherein the single thermal focus is formed without electronic focusing and without a lens,wherein a portion of the ultrasound probe is configured for acoustic coupling to the skin surface;
wherein the piezoelectric ultrasound therapy element is configured for delivery of energy at a temperature sufficient to tighten at least a portion of the tissue at the depth under the skin surface,wherein the piezoelectric ultrasound therapy element is connected to the motion mechanism,wherein the motion mechanism comprises an encoder,wherein the motion mechanism moves the piezoelectric ultrasound therapy element to form a plurality of thermal lesions at the depth for tighten at least a portion of the tissue for reducing an appearance of skin laxity.

Abstract
A system and method for ultrasound treatment of skin laxity are provided. Systems and methods 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. In an embodiment, a treatment system and method can be configured for producing arrays of sub-millimeter and larger zones of thermal ablation to treat the epidermal, superficial dermal, mid-dermal or deep dermal components of tissue.
