Abstract
The invention is directed toward a micro-endoscope assembly for the ablation of 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 energy 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 assembly is inserted into a mammary duct and the interior of the duct is viewed until an abnormality is determined in the duct. The tissue and cells from the abnormality area are ablated, irrigated and aspirated through a suction channel to a collection device.
