Method and system for ultrasound treatment of skin
First Claim
1. An ultrasound treatment device for treating skin tissue, the device comprising:
- an ultrasound probe comprising an ultrasound therapy component,wherein the ultrasound therapy component comprises a single, 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 below a skin surface,wherein the single thermal focus is formed without electronic focusing and without a lens,wherein the ultrasound probe is configured for acoustic coupling to the skin surface,wherein the ultrasound probe is configured for delivery of the ultrasound therapy energy to heat the tissue below the skin surface to a temperature of greater than 60 degrees Celsius,wherein the tissue comprises at least a portion of at least one of the group consisting of;
a dermis and a fascia,wherein the piezoelectric ultrasound therapy element is configured for delivery of the ultrasound therapy energy at the temperature sufficient to denature at least a portion of the tissue in a region of interest,wherein the piezoelectric ultrasound therapy element delivers the ultrasound therapy energy at a frequency of between 2 MHz to 25 MHz,wherein the piezoelectric ultrasound therapy element forms a plurality of thermal lesions for treating the tissue.

Abstract
Methods and systems for treating skin, such as stretch marks through deep tissue tightening with ultrasound are provided. An exemplary method and system comprise a therapeutic ultrasound system configured for providing ultrasound treatment to a shallow tissue region, such as a region comprising an epidermis, a dermis or a deep dermis. In accordance with various exemplary embodiments, a therapeutic ultrasound system can be configured to achieve depth with a conformal selective deposition of ultrasound energy without damaging an intervening tissue. In addition, a therapeutic ultrasound can also be configured in combination with ultrasound imaging or imaging/monitoring capabilities, either separately configured with imaging, therapy and monitoring systems or any level of integration thereof.
