Electromechanical restoration of the micturition reflex.

Techniques for reflex simulation as a treatment for the neurologically impaired bladder must restore volitional control of bladder function. This paper outlines the engineering commitments necessitated by biological considerations and the exclusive biological problems that must be dealt with in order to accomplish this. An electromechanical system that includes patient controllable mechanisms to provide for retention of intravesical content interrupted by intermittent expulsion is then described.
