Abstract

Methods and systems for the destruction of adipose tissue are disclosed. A method is provided for creating a surface map corresponding to a volume of adipose tissue for noninvasive treatment, and additional methods are provided for the treatment of the adipose tissue.

Claims

1. A method for projecting a volume of tissue onto a skin surface in preparation for a noninvasive cosmetic therapy procedure, the method comprising the steps of:

determining a volume of tissue suitable for a noninvasive cosmetic therapy procedure; and

creating a surface area map corresponding to said volume of tissue on a skin surface wherein said surface area map provides sufficient volumetric information to guide a user in conducting said noninvasive cosmetic therapy procedure.

2. The method of claim 1, wherein said creating step further comprises dividing said surface area into a plurality of individual treatment sections.

3. The method of claim 1, wherein said non-invasive cosmetic therapy procedure uses high intensity ultrasound.

4. The method of claim 1, wherein said non-invasive cosmetic therapy procedure uses high intensity focused ultrasound.

5. The method of claim 1, wherein the determining step further comprises scanning a volume of tissue using an imaging device.

6. A method for initiating a reduction in a volume of adipose tissue comprising the step of:

moving a therapeutic high intensity ultrasound transducer over a patient skin surface while emitting high intensity ultrasound into a volume of adipose tissue such that a biological response is initiated that leads to a reduction in said volume of adipose tissue.

7. The method of claim 6, wherein the applying step is done by continuous sweeps of the energy applicator.

8. The method of claim 6, wherein the applying step is done by position jumping of said energy applicator.

9. The method of claim 6, wherein the applying step is done by time delay jumping of said energy applicator.

10. The method of claim 6, wherein the transducer is a high intensity focused ultrasound transducer.

11. A method for reducing a volume of adipose tissue in a patient comprising the steps of:

moving a high intensity ultrasound transducer over a skin surface; and

irradiating a volume of adipose tissue below said skin surface using said high intensity ultrasound transducer wherein said transducer deposits an energy flux value of at least 35 J/cm².

12. The method of claim 11, wherein the transducer is capable of depositing an energy flux value up to 456 J/cm².

13. The method of claim 11, wherein the transducer is moved over a patient surface in a continuous sweeping motion.

14. The method of claim 11, wherein the transducer is moved over the patient body in a jumping manner.

15. A method of destroying adipose tissue using high intensity focused ultrasound, the method comprising the steps of:

determining a volume of adipose tissue to be treated;

marking out a corresponding surface area of skin;

dividing the surface area into a plurality of individual treatment sections;

applying therapeutic ultrasound energy to one section of said plurality of individual treatment sections with an ultrasound transducer until sufficient energy has been deposited to at least partially destroy the adipose tissue.

16. The method of claim 15, wherein the step of applying therapeutic ultrasound energy further comprises moving said ultrasound transducer in a manner such that sequential applications of ultrasound energy are spaced apart to non-adjacent sections.

17. The method of claim 15, wherein the step of applying therapeutic ultrasound energy further comprises providing a timing delay to the treatment of a physically adjacent section.

18. The method of claim 15, wherein the step of applying therapeutic ultrasound energy further comprises scanning a therapy transducer across said surface area at a velocity and line spacing sufficient to promote a cooperative effect of thermal energy build up in said adipose tissue.

19. The method of claim 15, wherein the step of applying therapeutic ultrasound energy further comprises creating an energy flux level in the adipose tissue in excess of 35 J/cm².

20. A system for coupling a high intensity focused ultrasound transducer to a patient comprising:

a fluid circuit for conveying a coupling fluid;

a pump for circulating coupling fluid through the fluid circuit;

a vacuum chamber connected to apply a pressure gradient to said fluid circuit such that dissolved gasses are drawn out of said coupling fluid;

a filter for removing particulate matter; and

a coupling reservoir connected to said circuit for coupling a transducer to a patient.
