Patent ID: 8082024

Claim:
An apparatus for visually assessing and detecting abnormalities in biological tissue in vivo, the apparatus comprising: an emitter for emitting a plurality of ultra-violet (UV) light beams having different excitation wavelengths suitable for causing biological tissue to emit fluorescence at an emission wavelength, wherein the emitter comprises a plurality of light-emitting diodes (LEDs) and each of the plurality of LEDs emits a UV light beam at a different wavelength of a plurality of predetermined wavelengths so as to be able to excite different tissue fluorophores; a detector for detecting the fluorescence; a controller for controlling the emitter and detector; a transmitter for transmitting data received from the detector to a remote receiver, the transmitter being controlled by the controller; and a transport capsule for containing at least the emitter, the detector, the controller and the transmitter.
