Abstract

A method and system for noninvasive face lifts and deep tissue tightening are disclosed. An exemplary method and treatment system are configured for the imaging, monitoring, and thermal injury to treat the SMAS region. In accordance with an exemplary embodiment, the exemplary method and system are configured for treating the SMAS region by first, imaging of the region of interest for localization of the treatment area and surrounding structures, second, delivery of ultrasound energy at a depth, distribution, timing, and energy level to achieve the desired therapeutic effect, and third to monitor the treatment area before, during, and after therapy to plan and assess the results and/or provide feedback.

Claims

1. A method of providing a treatment to a facial skin surface, the method comprising:

identifying a portion of the facial skin surface above a treatment region comprising a SMAS layer;

delivering ultrasound energy to the treatment region; and

ablating a portion of the SMAS layer with the ultrasound energy;

thereby improving an appearance of the facial skin surface.

2. The method according to claim 1, further comprising acoustically coupling an ultrasound source to the facial skin surface.

3. The method according to claim 1, further comprising emitting the ultrasound energy from an ultrasound source.

4. The method according to claim 1, further comprising ablating a portion of a muscular fascia layer in the treatment region.

5. The method according to claim 1, further comprising shrinking the SMAS layer.

6. The method according to claim 1, further comprising creating at least one lesion with the ultrasound energy in the treatment region.

7. The method according to claim 1, further comprising coagulating at least a portion of the SMAS layer.

8. The method according to claim 1, further comprising imaging the treatment region.

9. The method according to claim 1, further comprising tightening skin on a surface of the treatment region.

10. The method according to claim 1, further comprising performing a face lift.

11. A method for providing a noninvasive face lift, the method comprising:

imaging with ultrasound a region of interest of a face, the region of interest comprising a SMAS layer;

delivering ultrasound energy from a transducer probe to the region of interest; and

ablating a portion of the SMAS layer in the region of interest with the ultrasound energy, thereby tightening skin on the face.

12. The method according to claim 11, wherein the imaging comprises localizing the SMAS layer.

13. The method according to claim 11, wherein the delivering ultrasound energy comprises adjusting spatial and temporal parameters based on imaging of the SMAS layer.

14. The method according to claim 11, wherein the ablating the SMAS layer further comprises ablating a portion of at least one of skin, dermis, muscular fascia, and adipose, in addition to the SMAS layer.

15. A method for administering noninvasive treatment to skin on a face, the method comprising:

identifying a treatment region positioned on a face and comprising a skin layer and a SMAS layer;

coupling an ultrasound transducer to the treatment region;

directing ultrasound energy from the ultrasound transducer into the treatment region; and

ablating a portion of the SMAS layer with the ultrasound energy, thereby creating at least one lesion in the SMAS layer and tightening a portion of the skin on the face.

16. The method according to claim 15, further comprising ablating a portion of at least one of a skin layer, dermis layer, muscular fascia, and adipose tissue.

17. The method according to claim 16, further comprising creating a lesion in the portion of at least one of a skin layer, dermis layer, muscular fascia, and adipose tissue.

18. The method according to claim 15, further comprising imaging at least one of the skin layer and the SMAS layer in the treatment region.

19. The method according to claim 15, further comprising shrinking a portion of the SMAS layer.

20. The method according to claim 15, further comprising improving an appearance of the skin on the face.
