Abstract

Cellulite is treated by severing septae, which interconnects the skin with the underlying muscle. The septae may be severed in connection with a liposuction procedure or independent of a liposuction procedure.

the body is flexible.

13. A method of dissecting septae which extend between the skin and muscle, comprising the steps of:

providing a septae cutting device having a body and a sensing element;

moving the body through tissue in an area between skin and muscle so that tissue contacts the sensing element as the body is moved;

cutting septae which affect the sensing element a threshold amount, wherein tissue which does not affect the sensing element the threshold amount is not cut.

14. The method of claim 13, wherein:

the sensing element measures deflection.

15. The method of claim 13, wherein:
