Abstract

Methods for treating skin and subcutaneous tissue with energy such as ultrasound energy are disclosed. In various embodiments, ultrasound energy is applied at a region of interest to affect tissue by cutting, ablating, micro-ablating, coagulating, or otherwise affecting the subcutaneous tissue to conduct numerous procedures that are traditionally done invasively in a non-invasive manner. Methods of lifting sagging tissue on a face and/or neck are described.

Claims

1. A method of lifting facial tissue, the method comprising:

positioning a portion of an ultrasound probe system on a facial skin surface, the ultrasound probe system comprising a movement mechanism, a therapy element, and an imaging element,

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

imaging, with the imaging element, a region of interest under the facial skin surface, the region of interest comprising a tissue comprising at least one of muscle, muscular fascia, fat, and superficial muscular aponeurosis system (SMAS) tissue;

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

using the therapy element to treat the region of interest;

wherein the therapy element is coupled to the movement mechanism within the ultrasound probe system;

wherein the therapy element is configured for targeted delivery of ultrasound energy to form a thermal lesion with at least a temperature sufficient to treat at least a portion of the tissue at a fixed depth under the facial skin surface; and

activating the movement mechanism within the ultrasound probe system to move the therapy element to form a plurality of the thermal lesions at the fixed depth to treat the tissue in the region of interest,

wherein the plurality of thermal lesions results in a face lift.

2. The method of claim 1, wherein positioning a portion of the ultrasound probe system on the facial skin surface comprises positioning the portion of the ultrasound probe system on a preauricular region of the face.

3. The method of claim 1, wherein positioning a portion of the ultrasound probe system on the facial skin surface comprises positioning the portion of the ultrasound probe system on a frontal region of the face.

4. The method of claim 1, wherein positioning a portion of the ultrasound probe system on the facial skin surface comprises positioning the portion of the ultrasound probe system on a mandibular region of the face.

5. The method of 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.

6. The method of claim 1, wherein the fixed depth of the lesion is within a range of 3 mm to 9 mm from the facial skin surface.

7. The method of claim 1, wherein the activating the movement 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.

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

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

10. A method of treating sagging skin on a face or neck, comprising:

providing a probe that emits ultrasound energy;

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

delivering therapeutic ultrasound energy to the region at a treatment frequency of between 4 MHz and 15 MHz,

wherein the therapeutic ultrasound energy thermally treats at least one of the group consisting of subcutaneous fat, muscle, and connective tissue at a specific depth under the skin surface to reduce skin sagging on the face or neck.

11. The method of claim 10, wherein delivering therapeutic ultrasound energy comprises delivering ultrasound energy from a single therapy element in the probe.

12. The method of claim 11, 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.

13. The method of claim 10, further comprising treating a superficial muscular aponeurosis system (SMAS).

14. The method of claim 10, further comprising imaging the tissue under the skin surface.

15. The method of claim 10, wherein the specific depth is up to 9 mm under the skin surface.

16. A method of lifting sagging skin on a face or neck, comprising:

identifying a region of sagging skin on a face or neck;

providing an ultrasonic probe that emits ultrasound energy;

coupling the ultrasonic probe to a skin surface in a region selected from the group consisting of one or more of the following regions;

a preauricular region, a frontal region, and a mandibular region;

delivering therapeutic ultrasound energy at a treatment frequency of between 4 MHz and 15 MHz,

wherein the therapeutic ultrasound energy treats at least one of the group consisting of subcutaneous fat, muscle, and connective tissue at a specific depth under the skin surface to lift the sagging skin.

17. The method of claim 16, wherein delivering therapeutic ultrasound energy comprises delivering ultrasound energy at a fixed depth up to 9 mm from the skin surface at a temperature in the range of 60-90 degrees Celsius.

18. The method of claim 16,

wherein delivering therapeutic ultrasound energy comprises delivering ultrasound energy from a single therapy element in the probe, and

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.

19. The method of claim 16, further comprising treating a superficial muscular aponeurosis system (SMAS).

20. The method of claim 16, further comprising imaging the tissue under the skin surface.
