1. A method for reducing sweat, the method comprising:
- positioning a probe on a skin surface, the probe comprising at least one piezoelectric ultrasound therapy element;
targeting a region of interest under the skin surface, wherein the region of interest comprises at least one sweat gland; and
using the at least one piezoelectric ultrasound therapy element to thermally treat the at least one sweat gland in the region of interest to reduce sweat,wherein the at least one piezoelectric ultrasound therapy element is configured to deliver energy at a frequency in a range of 500 kHz to 15 MHz to a depth of 1 mm to 7 mm below the skin surface to heat the at least one sweat gland.

Abstract
A method and system for energy-based (e.g., ultrasound treatment and/or other modalities) of sweat glands are provided. An exemplary method and system for targeted treatment of sweat glands can be configured in various manners, such as through use of therapy only, therapy and monitoring, imaging and therapy, or therapy, imaging, and monitoring, and/or through use of focused, unfocused, or defocused ultrasound (or other energy) through control of various spatial and temporal parameters. As a result, ablative energy can be deposited at the particular depth at which the aberrant sweat gland population is located below the skin surface.

13. A method for reducing sweat, the method comprising:
-
identifying a region of interest on a subject, wherein the region of interest comprises at least one overactive sweat gland; placing a thermal energy delivery probe on a skin surface overlying the region of interest; activating the thermal energy device via targeting the thermal energy at a frequency in a range of 500 kHz to 15 MHz, via the energy delivery probe, through the skin surface to the region of interest thereby treating the at least one overactive sweat gland via a plurality of thermal energy foci in the region of interest using an automated motion mechanism for heating the at least one overactive sweat gland. - View Dependent Claims (14, 15)

16. A method for reducing sweat, the method comprising:
-
transmitting energy at a frequency in a range of 500 kHz to 15 MHz, via at least one piezoelectric ultrasound therapy element, to deliver a thermal energy to a first sweat gland; and moving the at least one piezoelectric ultrasound therapy element, via an automatic motion mechanism, to deliver a thermal energy to a second sweat gland, wherein the at least one piezoelectric ultrasound therapy element is configured with at least one of the group consisting of a spherical focus and a cylindrical focus, wherein the thermal energy reduces an amount of sweat produced from the first and second sweat glands. - View Dependent Claims (17, 18, 19, 20)
