A system for controlling bladder evacuation includes first and second implanted stimulation systems having electrodes respectively positioned on nerves controlling external sphincter and bladder functions, and an electronic control system which operates to generate and transmit electrical sphincter stimulation pulses to the first stimulation system. When it is desired to evacuate the bladder, a switch is closed causing the electronic control system to discontinue the external sphincter stimulation and, after a predetermined delay, to generate and transmit electrical bladder stimulation pulses to the second stimulation system. After a predetermined time, the bladder stimulation is automatically stopped. After another predetermined delay, the electronic control system resumes the generation and transmission of sphincter stimulation pulses to the first stimulation system. |

DETAILED DESCRIPTION We claim: 1.
An electronic control system for sending stimulation signals to first and second stimulation implanted in a body, said stimulation systems each including at least one receiver and an electrode associated with said receiver, the electrode of said first stimulation system being positioned on a nerve controlling one bodily function and the electrode of said second stimulation being positioned on a nerve controlling another bodily function, the electronic control system comprising: a first pulse generating and transmitting means for generating and transmitting a series of electrical pulses to the receiver of said first stimulation system, a second pulse generating and transmitting means for generating and transmitting a series of electrical pulses to the receiver of said second stimulation system, a manually operable member, means for turning off said first pulse generating and transmitting means in response to operation of said manually operable member, and, after a first preselected time delay, for turning on said second pulse generating and transmitting means, means operable at a selected time period after turning on of said second pulse generating and transmitting means for turning off said second pulse generating and transmitting means and, after a second preselected time delay, for turning back on said first pulse generating and transmitting means.
2.
An electronic control system as set forth in claim 1, wherein each of said first and second pulse generating and transmitting means has the function of generating and transmitting time spaced bursts of pulses.
3.
An electronic control system as set forth in claim 1, wherein said first stimulation system includes a second receiver and an electrode associated with said second receiver, the two electrodes of said first stimulation system being positioned on nerves both controlling said one bodily function, said electronic control system being further characterized in that said first pulse generating and transmitting means has the function of generating and transmitting a series of electrical pulses to the two receivers of said first stimulation system
