ENDOMETRIAL ABLATION METHOD AND APPARATUS

摘要

An apparatus and method for effecting necrosis of a tissue lining of uterine endometrium, by introducing an applicator comprising a distendable bladder and catheter. The bladder is pre-shaped to approximate the bicornual shape of the uterus and is manufactured from bio-compatible, non-allergenic specification quality material. There are two pre-shaped sizes; one for nulliparous uteri and; one for parous uteri. The bladder is connected to a catheter that contains a non-metallic spring method to ensure the proper deployment and shaping of the bladder. The bladder is then distended by introducing a heated, by means external to the bladder and catheter, (above 220.degree. F) bio-compatible fluid under pressure (40 - 150 mm Hg) for a period of 30 - 90 seconds and then a repeat procedure of 30 - 90 seconds. The regulation of said apparatus is by means located external to the uterus, and ensures thermal ablation of substantially the entire tissue lining of the endometrium.
