Abstract
A method and system for delivering energy to affect the signs of aging is described. Energy is delivered to a target volume of a muscle such that the energy creates a lesion in the target volume. A characteristic of the lesion is controlled to affect movement of the muscle.
Claims
AMENDED CLAIMS received by the International Bureau on 10 September 2007 (10.09.2007)
8. The method of claim 1, wherein producing a map of a muscle (56) comprises acquiring an echo image of the muscle (56) from echoes generated by reflections of ultrasound pulses directed towards the muscle (56).
9. A method for reducing signs of aging, the method comprising: producing a map of SMAS tissue; using the map, locating a target volume (44) of the SMAS tissue; delivering energy (42) to the target volume (44) such that the energy (42) creates a lesion (46) in the target volume (44), the lesion (46) having a characteristic selected for affecting movement of the SMAS tissue; and selecting the characteristic to induce contraction of the SMAS tissue in a specified direction.
10. The method of claim 9, further comprising selecting the characteristic to release the SMAS tissue from muscle tissue causing skin attached to the SMAS tissue to be pulled in a desired direction.
11. The method of claims 9 or 10, wherein the characteristic comprises at least one of: a size, a shape, an orientation, a depth below an epidermal surface, and a location relative to another lesion.
12. The method of claim 9, wherein delivering energy (42) comprises selecting the energy (42) to be ultrasound.
13. The method of claim 9, wherein delivering energy (42) comprises selecting the energy (42) to be radio frequency electromagnetic energy.
14. The method of claim 13, further comprising; selecting a frequency of the ultrasound to be a value within a range of 4 to 8 MHz; and
selecting a power of the ultrasound to be a value within a range of 60 to 8OW.
15. The method of claim 9, wherein producing a map of SMAS tissue comprises acquiring an echo image of the SMAS tissue from echoes generated by reflections of ultrasound pulses (42) directed towards the SMAS tissue.
16. A method for reducing signs of aging, the method comprising; producing a map of target tissue including muscle (56) and SMAS tissue; using the map, locating a target volume (44) of the target tissue; delivering energy (42) to the target volume (44) such that the energy creates a pattern of lesions in the target volume (44); and selecting the pattern to impact the degree and direction of movement of the target tissue.
17. The method of claim 16, further comprising selecting the pattern to be one of: a square, triangle, polygon, grid, criss-cross pattern, circle, oval, and coil.
IS. The method of claim 16, further comprising selecting the pattern to be a matrix of lesions spaced approximately equidistant from each other.
19. The method of claim 18, further comprising: selecting the lesions to be approximately lmm3 in volume; and selecting spacings between the lesions to be approximately lmm.
20. The method of claim 16, wherein delivering energy (42) comprises selecting the energy (42) to be ultrasound.
21. The method of claim 16, wherein delivering energy (42) comprises selecting the energy (42) to be radiofrequency electromagnetic energy.
22. The method of claims 16, 17, or 18, wherein selecting the pattern to impact the degree and direction of movement of the target tissue comprises selecting a density of the lesions to achieve a desired degree of contraction of the SMAS tissue within the target volume (44).
23. The method of claim 16, 17, or 18, wherein selecting the pattern to impact the degree and direction of movement of the target tissue comprises selecting spacings between the lesions to achieve a desired degree of paralysis of the muscle tissue (56) within the target volume (44),
24. A system (10) for delivering energy (42) to affect the signs of aging, the system (10) comprising: an ablating transducer (52) configured to deliver ablative radiation (42) at a power sufficient to ablate muscle tissue of a muscle (56); control circuitry (12) in communication with the ablating transducer (52), the control circuitry (12) configured to receive lesion pattern specifications and stimulate the ablating transducer (52) to produce a pattern of lesions within a target volume (44) of the muscle (56), the pattern being in accordance with the lesion pattern specifications and selected to impact a degree of paralysis of the muscle (56),
25. The system (10) of claim 24, further comprising an imaging transducer (54) configured to deliver ultrasound radiation at a power sufficient to produce an echo image of the target volume (44) without damaging tissue within the target volume (44).
26. The system (10) of claim 24, wherein the ablative radiation (52) is ultrasound radiation.
27. The system (10) of claim 24, wherein the lesion pattern specifications include size and depth specifications of the lesions of the pattern.
28. The system (10) of claim 24, wherein the pattern comprises lesions of approximately lmm3 in size and spaced approximately 1 mm apart from each other.
29. The system (10) of claim 24, wherein the target volume (44) includes SMAS tissue and the pattern is further selected to impact the degree and direction of movement of SMAS tissue.
