Abstract

A system and method for treating cellulite tissue and related conditions comprising apparatus configured to transmit shear and other vibration modes beneath a patient'"'"'s skin sufficient to break down connective tissue so that pocketing and dimpling of adjacent skin is ameliorated.

Claims

1. A method of treating target dimpled and pocketed skin and adjacent tissue comprising:

a) removably attaching, using adhesive means, a solid vibration transducer to a surface of a patient'"'"'s skin in an area to be treated so as to prevent movement between the solid transducer and the surface of the patient'"'"'s skin in the area to be treated;

b) coupling the solid transducer to a mechanically vibrating vibration source having a variable frequency, variable vibration modes, and variable input energy; and

c) controlling the variable frequency, the vibration mode, and the input energy using a frequency that matches the resonant frequency of the tissue below the surface of the skin so as to produce at least one standing wave in a combination of the solid transducer and the target skin and adjacent tissues such that a displacement wave is formed that is phase-shifted by a quarter-wavelength with a stress wave;

d) whereby sufficient stress is achieved a quarter-wavelength below the surface of the patient'"'"'s skin in the area being treated to bring about mechanical yield or failure of connective tissue causing the dimpled and pocketed skin, without causing stress to the surface of the patient'"'"'s skin in the area being treated.

2. The method as claimed in claim 1 wherein the at least one standing wave is selected from the group consisting of a standing compressive wave, a standing torsion wave, a standing Raleigh wave, a standing shear wave, and combinations thereof in a plurality of dimensions and amplitudes.

3. The method as claimed in claim 2 wherein the at least one standing wave is a standing torsion wave.

4. The method as claimed in claim 2 wherein the at least one standing wave is a standing shear wave.

5. The method as claimed in claim 2 wherein the at least one standing wave is a combination of at least two of a standing compressive wave, a standing torsion wave, a standing Raleigh wave, and a standing shear wave.

6. The method as claimed in claim 1 wherein the vibration is multi-modal.

7. The method as claimed in claim 6 wherein the vibration comprises a plurality of modes of shear vibration.

8. The method as claimed in claim 1 wherein said controlling step comprises using feedback to adjust at least one of the frequency, mode, and energy of the vibration.
