摘要： An apparatus, and method for endometrial ablation by heating an inflation medium within a distensible bladder positioned within a uterus of a patient. The apparatus comprises an elongate tubular member, a handle, a distensible bladder and a heating element disposed within said distensible bladder. The system includes a controller configured for providing and regulating electric current to the heating element. The controller also includes a pressure sensor for regulating the pressure in the distensible bladder. Pressure and temperature displays and other operator controls are located on the controller unit. The method for performing endothelial ablation comprises inserting the distensible bladder and a portion of the tubular member into a uterus of a patient. The inflation medium within the distensible bladder is heated by providing electric current to the resistive wire of the heating element. The inflation medium within the distensible bladder is heated to a desired temperature and temperature and pressure within the distensible bladder are maintained for a desired time interval. The distensible bladder is then deflated and removed from the uterus.
