An assembly of devices intended to generate and administer microwave energy for localized non-vascular soft-tissue ablation, typically to treat tumours, hydatid cysts and/or menorrhagia. It consists of an electrically-powered microwave energy generator, a user interface, and controls; a microwave ablation probe (not included) is used for energy application to the target area. It is intended to be used in percutaneous, laparoscopic, natural orifice or open surgery procedures to ablate tissue typically in the liver, lung, pancreas, kidney, and uterus (e.g., endometrial ablation).
