Method and system for treating stretch marks

摘要

Methods and systems for treating 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 and a deep dermis. In accordance with various exemplary embodiments, a therapeutic ultrasound system can be configured to achieve depth from 0 mm to 1 cm with a conformal selective deposition of ultrasound energy without damaging an intervening tissue in the range of frequencies from 2 to 50 MHz. 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.

1. An ultrasound treatment system for treating skin tissue, the system comprising:
a control system; a display; and an ultrasound probe comprising an ultrasound imaging element, a motion mechanism, and an ultrasound therapy component,
wherein the ultrasound therapy component consists of a single, spherically-focused ultrasound therapy element,wherein the ultrasound therapy element is configured to provide a single mechanical focus,wherein the single mechanical focus is configured to provide ultrasound therapy energy in the 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 an ultrasound 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 a dermis and a fascia, wherein the control system comprises a processor and power supply; wherein the ultrasound imaging element is in communication with the display, wherein the ultrasound imaging element is configured for imaging a region of interest under the skin surface, wherein the region of interest comprises the tissue, wherein the display is configured to display an image of the region of interest, wherein the ultrasound therapy element is in communication with the control system, wherein the ultrasound therapy element is configured for delivery of energy at a temperature sufficient to denature at least a portion of the tissue in the region of interest, wherein the ultrasound therapy element delivers ultrasound energy at a frequency of between 2 MHz to 25 MHz, wherein the ultrasound therapy element is connected to a portion of the motion mechanism, wherein the motion mechanism is in communication with the control system, wherein the motion mechanism moves the ultrasound therapy element to form a plurality of thermal lesions for treating the tissue.
