  • Endoscopic fiberoptic fluorescence spectrometer
    Patent number: 4981138
    Abstract: A method of detecting pre-malignant lesions in the gastrointestinal tract comprises positioning an opitcal fiber in a patient's gastrointestinal tract and transmitting ultraviolet laser light through said optical fiber means to cause the tissue of the gastrointestinal tract illuminated by the laser to fluoresce in the near visible band of frequencies. The fluorescence spectrum is returned through the optical fiber to a spectrum analyzing means which analyzes the spectrum in the wavelength range of 350 to 700 nm to determine whether the tissue caused to fluoresce is pre-malignant. Tissue so diagnosed may be ablated by a high power laser using the same fiberoptic system.
