Abstract
An apparatus for treating a subcutaneous fat region is provided. The apparatus includes a housing that has a skin contacting portion defining a chamber. The apparatus also includes a first spaced region in the housing through which a coolant passes and a second spaced region in the housing that is at least partially evacuated of air. The apparatus further includes a source of electromagnetic radiation, a source of vacuum in fluid communication with the chamber, and a source for the coolant.
Claims14
A method for treating a subcutaneous fat region, comprising:
- delivering a uniform energy distribution of electromagnetic radiation to a surface of skin overlying the subcutaneous fat region using a skin contacting applicator, wherein the electromagnetic radiation is provided by a plurality of laser diodes spaced in a plurality of rows and columns;
- wherein the distance between the rows and columns of laser diodes and height of the laser diodes from the surface of the skin are chosen to result in uniform energy distribution of the electromagnetic radiation on the skin, and
- applying a coolant and removing thermal energy from an epidermal region and at least a portion of a dermal region of skin overlying the subcutaneous fat region without the coolant being directly exposed to the surface of the skin,
- wherein a height of the laser diodes from the surface of the skin is calculated by the equation:
- dz=gx/2×tan(angs/2)×{Overlap Factor}
- wherein (dz) denotes the height of the laser diodes from the surface of the skin, (gx) denotes the distance between the columns and (angs) denotes the slow-axis diversion.
