1. An ultrasound probe for treatment of skin laxity, the ultrasound probe comprising:
- a housing, wherein inside the housing comprises a motion mechanism and an ultrasound transducer,wherein the ultrasound transducer comprises a single active focused piezoelectric ultrasound therapy element,wherein the piezoelectric ultrasound therapy element is configured to provide a single mechanical focus configured to provide ultrasound therapy energy in a form of a single thermal focus in a tissue at one or more depths below a skin surface to treat the tissue,wherein the tissue comprises 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 a portion of the housing 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 one or more depths under the skin surface,wherein the single mechanical focus is formed without electronic focusing and without a lens,wherein the piezoelectric ultrasound therapy element is connected to the motion mechanism,wherein the motion mechanism is configured to operate with an encoder, wherein the motion mechanism is configured to move the piezoelectric ultrasound therapy element to form a plurality of thermal lesions at the one or more depths for tightening at least a portion of the tissue for reducing skin laxity.

Abstract
A probe 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.
