Q. How does the HTA System work?A. First, your cervix will be slightly dilated to allow the introduction of the telescope through the vagina, into the cervix and then into the uterus. This gives your gynecologist a view of the inside of your uterus to assure proper positioning. Then, your uterus will be filled with room temperature saline solution to gently clean and flush the uterus. The fluid will be gradually heated to 90ÂșC and circulated in the uterus for ten minutes in order to treat the endometrium (lining of the uterus). When the treatment is complete, the uterus will be flushed with room temperature saline to cool the uterus and the probe. Your uterine lining has been treated and will slough off similar to a menstrual period over the next few weeks.
