METHOD FOR TRANSCERVICAL INTRAUTERINE STERILIZATION Russian patent published in 2006 - IPC A61B17/42 A61B18/22 

FIELD: medicine, gynecology.

SUBSTANCE: before photocoagulation it is necessary to remove mucous layer in intramural department uterine tube up to the level of fibrinous fibers of submucous membrane, close the passability of isthmus and intramural department of uterine tube due to photocoagulation with scattered laser radiation. A light guide should be replaced from isthmus' lumen through intramural department towards uterine cavity at stops for irradiation purpose by developing dead-end septa along forming closed sections. At photocoagulation one should apply a biological protein hematofibrinous intratissue solder of removed mucous layer. The innovation provides tight tissue welding, decreases traumatism of sterilization due to applying a biological solder, moreover, by keeping viability of epithelial parts in intramural department of uterine tube.

EFFECT: higher efficiency.
