System and method for treating muscle, tendon, ligament and cartilage tissue

1. A method of treating a sagging brow, the method comprising:

acoustically coupling an ultrasound probe system to a skin surface on a brow, the ultrasound probe system comprising an imaging element, a therapy element, and a motion mechanism;

wherein the motion mechanism is controlled by a control system in communication with the ultrasound probe;

using the imaging element to image a region of interest under said skin surface at a fixed depth, the region of interest comprising a tissue comprising a portion of at least one of muscular fascia, fat, and SMAS tissue;

wherein the region of interest at said fixed depth is displayed on a display system, said display system being electronically connected to said imaging element;

using the therapy element to treat said region of interest;

wherein the therapy element is coupled to the motion mechanism within the probe;

wherein the therapy element is configured for targeted delivery of ablative ultrasound energy to form a thermal lesion with at least a temperature sufficient to treat at least a portion of the tissue at the fixed depth of up to about 9 mm from the skin surface; and

activating the motion mechanism within the probe to move the therapy element to form a plurality of said thermal lesions along a line at the fixed depth into said tissue to cause any one of the group consisting of ablation, deactivation, and shrinkage of at least a portion of the tissue,

wherein the plurality of thermal lesions facilitates a tightening of the tissue that leads to a brow lift.

2. The method according to claim 1 , wherein the imaging element is configured to image with an imaging frequency of between 2 kHz to 75 MHz and the therapy element is configured to treat with a treatment frequency of between 4 MHz and 15 MHz.

3. The method according to claim 1 , wherein the fixed depth of the lesion is within a range of 0 to 5 mm from the skin surface.

4. The method according to claim 1 , wherein the fixed depth of the lesion is within a range of 1 mm to 6 mm from the skin surface.

5. The method according to claim 1 , wherein said activating the motion mechanism comprises communication between and at least two of the group consisting of a control system, an accelerometer, an encoder and a position/orientation device.

6. The method according to claim 1 , wherein the temperature of the thermal lesion is in the range of 60-90 degrees Celsius.

7. The method according to claim 1 , wherein the imaging element and the therapy element are combined in a dual-mode imaging/therapy transducer.

8. A method of treating skin on a face, comprising:

providing a probe that emits ultrasound energy;

coupling the probe to a skin surface on the face proximate a region comprising subcutaneous fat, muscle, and connective tissue;

imaging the region with said probe;

applying a sufficient amount of therapeutic ultrasound energy to coagulate at least one of the group consisting of subcutaneous fat, muscle, and connective tissue at a specific depth to reduce skin sagging on the face.

9. The method according to claim 8 , wherein a sufficient amount of ultrasound energy is emitted to ablate the subcutaneous fat, muscle, and connective tissue responsible for wrinkles.

10. The method according to claim 8 , wherein applying step comprises delivery of the therapeutic ultrasound energy from a single therapy element in the probe.

11. The method according to claim 10 , further comprising activating a motion mechanism to move the single therapy element to form a plurality of thermal lesions along a line in the region to reduce skin sagging on the face.

12. The method according to claim 8 , further comprising treating a superficial muscular aponeurosis system (SMAS).

13. The method according to claim 8 , wherein the therapeutic ultrasound energy is provided at a treatment frequency of between 4 MHz and 15 MHz.

14. The method according to claim 8 , wherein the specific depth is up to 9 mm from the skin surface.

15. A method of reducing wrinkles on a brow with an imaging and therapy ultrasound transducer, the method comprising:

identifying a treatment area comprising at least one wrinkle in a skin surface proximate wrinkle causing subcutaneous tissue;

imaging at least a portion of the treatment area with an ultrasound transducer configured for both imaging and therapy; and

delivering ultrasound energy with the ultrasound transducer through the skin surface and into a portion of the treatment area comprising the wrinkle-causing subcutaneous tissue to cause thermal injury to a portion of the wrinkle-causing subcutaneous tissue, thereby reducing the at least one wrinkle on the skin surface.

16. The method according to claim 15 , wherein the delivering ultrasound energy is in a frequency range of 2 MHz to 25 MHz.

17. The method according to claim 15 , wherein the delivering ultrasound energy is at an energy level sufficient to cause the portion of the wrinkle-causing subcutaneous tissue to reabsorb into the body.

18. The method according to claim 15 , wherein the portion of the treatment area is at a depth of up to 9 mm from the skin surface.

19. The method according to claim 15 , further comprising activating a motion mechanism to move the ultrasound transducer to form a plurality of thermal lesions along a line in the portion of the treatment area to cause shrinkage of the subcutaneous tissue.

20. The method according to claim 15 , wherein the ultrasound transducer comprises a single therapy element configured for the delivering ultrasound energy to the portion of the treatment area.
