The invention is directed toward a micro-endoscope assembly for intraductal brachytherapy 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 cartridge is mounted in the second passageway. The assembly is inserted into a mammary duct and the interior of the duct is viewed until the abnormality to be treated is determined in the duct. The container is deposited adjacent the abnormal tissue area in the duct and left in place to produce localized radiation or other forms of energy.
A micro-endoscope assembly for intraductal brachytherapy of a mammary duct comprising a cylindrical guide tube having a diameter ranging from 0.5 mm to about 1.2 mm defining an internal passageway, a smaller cylindrical tube eccentrically formed in said cylindrical passageway of a smaller diameter than said tube internal cylindrical passageway to receive and guide an endoscope assembly, said smaller cylindrical tube forming together with an inner wall surface of said cylindrical guide tube at least a second passageway, an endoscope mounted in said smaller cylindrical tube, a plunger member moveably mounted within said second passageway adapted to move a cartridge which is treated to produce localized radiation adjacent tissue which is to be treated in said mammary duct.
A micro-endoscope assembly for intraductal brachytherapy of a mammary duct comprising a cylindrical guide tube having a diameter ranging from 0.5 mm to about 1.2 mm defining an internal cylindrical passageway, a smaller cylindrical tube eccentrically formed in said cylindrical passageway having a smaller diameter than said tube internal cylindrical passageway to receive and guide an endoscope, said smaller cylindrical tube forming together with an inner wail surface of said cylindrical guide tube at least a second passageway, and an endoscope mounted in said smaller cylindrical tube, a second conduit of a smaller diameter than the smaller cylindrical tube is mounted in said at least second passageway to divide said at least a second passageway into two separate divided sections and a plunger member moveably mounted within said at least a second passageway adapted to move a cartridge which can be treated to produce localized radiation adjacent tissue to be treated in said mammary duct.
A micro-endoscope assembly as claimed in claim 10 wherein said cartridge has a body which is constructed of a material selected from a group consisting of polyvinyl acetal, gelatin, collagen, and fibrin.
A micro-endoscope assembly as claimed in claim 10 wherein said cartridge comprises a body and a strand secured to said body.
A micro-endoscope assembly as claimed in claim 10 wherein said cartridge has a body which is constructed of compressed dry polyvinyl acetal.
