  • Electronic stimulator implant
    Patent number: 7519429
    Abstract: The present invention relates to lower urinary dysfunctions and more particularly to an electronic stimulator implant and method to improve bladder voiding and prevent bladder hyperreflexia. There is provided an electronic stimulator implant for which comprises a tonicity signal generator generating a tonicity signal which prevents bladder hyperreflexia combined with a voiding signal generator generating a voiding signal for voiding the bladder. The implant is connected to an end of an electrode, and the second end thereof is connected to a sacral nerve. When the voiding key (or switch) is activated, the voiding signal is generated which activates detrusor muscle contraction, causing bladder voiding. The voiding may be achieved without dyssynergia, by activating detrusor muscle contraction without activating external urethral sphincter contraction. The tonicity signal may be provided intermittently. The implant may be activated by a manually activated external controller.
