1. A system for stimulating the bladder of a mammal with energy supplied from a source exterior to said mammal including:

  • a. means exterior to said mammal for providing radio frequency energy of a predetermined time width and having a predetermined pulse repetition period larger than said time width;

    b. means including an antenna tuned to the radio frequency of means (a) and a storage capacitor for storing said energy during said time width, wherein said means (b) is encapsulated in a biologically inert substance for placing within a mammal;

    c. means for generating a stimulating pulse from the source of energy supply during the interval that means (a) does not emit radio frequency energy, said means includes a load and a second capacitor connected to said antenna and a first translating device in cascade with a second translating device, said second capacitor adapted to charge, during the time width of said means (a) to thereby bias said first translating device to cut off during said time width, and to discharge between the time widths to thereby allow said first translating device to conduct triggering said second translating device to conduct discharging said storage capacitor through said load across which a stimulating pulse is generated, said means being connected to said antenna and said storage capacitor and encapsulated in a biologically inert substance for placing within the mammal; and

    , d. means for conveying said stimulating pulse to said bladder wall including a plurality of electrodes for embedding in the walls of the bladder so that contractiOn of the bladder and voiding of urine from the same occur during the generation of said stimulating pulse.
