Abstract :
We propose an urination assist system implantable in a patient who has difficulty in urination caused by the neuropathic bladder in order to assist the urination. The proposed system assists the urination by directly pushing the bladder of the patient using shape memory alloys (SMA). Peltier elements are used to control the temperature in the system. The effectiveness of the proposed system is evaluated by experiment with a bladder model.
