The Methodist Ambulatory Surgery and Medical Center in San Antonio is the nation's unofficial capital for minimally invasive GYN, at least according to the facility's director of operations, Michelle Rhunke, RN. "If there's a new device out there, we've tried it," she says. Many of those devices treat patients who present with menorrhagia, the prolonged and heavy menstrual bleeding that can be caused by submucosal fibroids growing in the muscle along the inner lining of the uterus.
