A hand-held device designed to apply water vapour for the ablation of the interior lining of the uterus (endometrium) to treat dysfunctional uterine bleeding (menorrhagia). It includes a proximal handle attached to distal components consisting of an outflow tube, pressure sensors, and a shaft with balloons to control vapour application. It is used with a dedicated control unit (not included) which supplies energy for heating saline in the handle to create vapour. This is a single-use device.
