Abstract
A method and composition for effecting necrosis of a tissue lining of a mammalian body cavity, particularly a uterine endometrium, by introducing an applicator comprising a hysteroscope housing a first and a second catheter connected to a catheter into the uterus, distending the uterus by introducing CO.sub.2 gas under pressure, delivering a silver nitrate paste to the endometrium through the first catheter and allowing the paste to remain a sufficient amount of time to substantially cauterize the entirety of the tissue lining, particularly the endometrium and delivering an aqueous sodium chloride solution to the uterus through the second catheter thereby neutralizing the silver nitrate and rinsing the uterine cavity.
