First Claim
1. A trans-illumination device to facilitate visualization of tissues lying below the skin of a patient, comprising in combination:
- a) a base unit;
b) an electrical power source housed within the base unit;
c) a light head remote from the base unit, and including;
i) a first plurality of light emitting diodes (LEDs) for emitting light of a first wavelength in the visible spectrum; and
ii) a second plurality of LEDs for emitting light of a second wavelength in the visible spectrum, the second wavelength differing from the first wavelength;
the light head being adapted for placement against the patient'"'"'s skin for directing emitted light into the patient'"'"'s skin to illuminate tissues lying below the patient'"'"'s skin; and
d) an electrical cable coupled to the base unit and coupled to the light head for supplying electrical power from the base unit to the light head to selectively operate the first and second pluralities of LEDs.

Abstract
A trans-illumination device includes at least first and second sets of LEDs of two or more different colors arranged in a light head placed against a patient'"'"'s skin. The LEDs are mounted to a printed circuit board in the light head. An electronic control circuit is coupled to the light head by an electrical cable to selectively operate the LEDs in two or more user-selected modes, with the ability to adjust the relative intensities of the different colors to best suit the physiology of the patient. The light head may have a U-shape to surround an area of interest while providing ready access thereto. The light head may be used with a disposable, detachable cover having lenses for directing light from the LEDs into the patient'"'"'s tissues.
