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 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.

2. The method of claim 1, wherein applying is done by continuous sweeps of the energy applicator.

3. The method of claim 1, wherein applying is done by position jumping of said energy applicator.

4. The method of claim 1, wherein applying is done by time delay jumping of said energy applicator.

5. The method of claim 1, wherein the transducer is a high intensity focused ultrasound transducer.

6. A method for reducing a volume of adipose tissue in a patient comprising:

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

while moving the transducer, 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.

7. The method of claim 6, wherein the transducer is capable of depositing an energy flux value up to 456 J/cm².

8. The method of claim 6, wherein the transducer is moved over a patient surface in a continuous sweeping motion.

9. The method of claim 6, wherein the transducer is moved over the patient body in a jumping manner.

10. 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.

11. The method of claim 10, wherein 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.

12. The method of claim 10, wherein applying therapeutic ultrasound energy further comprises providing a timing delay to the treatment of a physically adjacent section.

13. The method of claim 10, wherein 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.

14. The method of claim 10, wherein applying therapeutic ultrasound energy further comprises creating an energy flux level in the adipose tissue in excess of 35 J/cm².
