Abstract
The invention is directed toward a micro-endoscope assembly for the treatment of diseased tissue in breast ducts comprising a cylindrical guide tube with a distal end defining an internal cylindrical passageway, a first smaller cylindrical tube eccentrically formed in the cylindrical passageway of a smaller diameter than said tube internal cylindrical passageway to receive and guide an endoscope, the smaller cylindrical tube forming together with an inner wall surface of the cylindrical guide tube a second passageway. A light transmitting probe is mounted in the second passageway and is connected at the distal end of the guide tube with an energy transmitting device. The light probe is activated to generate light at a particular wavelength to cause the tissue to fluoresce and is again activated to generate light at a specific wavelength to necrose the diseased tissue.
