Method and apparatus for electromagnetically assisted liposuction
First Claim
1. An apparatus for preconditioning fatty tissue for liposuction, said apparatus comprising:
- a source of R-F energy;
an applicator body;
a first antenna mounted to said applicator body, said first antenna being transmissively connected to said R-F source;
a first R-F shield mounted to said first antenna, said first R-F shield being constructed of a material impermeable to R-F radiation, said first R-F shield being shaped, sized, and positioned to shield a user of said apparatus from R-F radiation and to direct R-F radiation from said first antenna in a first selected direction;
a second antenna mounted to said applicator body independently of said first antenna, said second antenna being transmissively connected to said R-F source;
a second R-F shield mounted to said second antenna independently of said first R-F shield, said second R-F shield being shaped, sized, and positioned to shield a user of said apparatus from R-F radiation and to direct R-F radiation from said second antenna in a second selected direction; and
a flexible connecting member on said applicator body, said flexible member connecting said first and second antennae together, said flexible connecting member being adapted to allow independent orientation of said first and second antennae in different said first and second directions.

Abstract
An improved method and apparatus for facilitating removal of fat from obese, or lipodystrophic patients, by external application of electromagnetic energy. After infiltrating the proposed zone with intumescing solution, radio frequency or microwave electromagnetic energy is applied via externally placed applicators to the body site of unwanted fatty tissue. The electromagnetic energy supplies heat to the fatty tissue and to the intumescing solution, aiding in subsequent fat removal by conventional, or preferably, ultrasound-assisted, or microwave-assisted, internal liposuction. Depth of tissue penetration is controllable by selection of the appropriate electromagnetic frequency and by varying the configuration of the applicators. Restricting the intumescing procedure to only the desired body sites subject to subsequent internal surgical intervention reduces unwanted heating of the underlying muscle or other organs. Multiple-frequency capability is incorporated in the power supply.

7. An apparatus for preconditioning fatty tissue for liposuction, said apparatus comprising:
-
a source of R-F energy; a controller for varying the radio frequency and power level of said R-F source; an applicator body; first and second antennae independently mounted to said applicator body, each said antenna being transmissively connected to said R-F source, said first and second antennae being connected by a flexible connecting member adapted to allow independent orientation of said first and second antennae in different selected first and second directions; first and second R-F shields mounted to said first and second antennae respectively, said first and second R-F shields being constructed of a material impermeable to R-F radiation, said first and second R-F shields being shaped, sized, and positioned to shield a user of said apparatus from R-F radiation and to direct R-F radiation from said first and second antennae in said different selected first and second directions; and first and second contact plates on said said first and second antennae respectively for contacting the skin of a patient, said contact plates being constructed of a material substantially permeable to R-F radiation.
