The Thermachoice™ device uses a balloon placed in the uterine cavity through the cervix. Hot water is circulated inside the balloon.
The Vestablate™ balloon has metal electrodes on the surface, with thermisters in each electrode to monitor temperature. When the device is activated, radio frequency current is applied to the electrodes, and a computer controls the temperature used to destroy the endometrium.
Most women who have menorrhagia (abnormally heavy menstrual periods) that is not controlled by medicine, and do not have other problems that require a hysterectomy should consider endometrial ablation. The risk is low in the hands of a physician skilled in the procedure. The procedure is done on an outpatient basis, and most women are able to return to their regular activities within a few days. A small percentage of properly selected women having an ablation will eventually need a hysterectomy, but the vast majority will not.
The Thermachoice™ device is a Uterine Balloon Therapy system that broadens a woman's choice in treatment for excessive menstrual bleeding. It is a minimally invasive alternative to a hysterectomy or other surgical procedures for pre-menopausal women who are having heavy periods due to benign causes. This simple 30-minute procedure uses heat to treat the lining of the uterus (the endometrium) and requires no incision.
