Abstract: Urinary control by electrical stimulation of the sphincter and bladder muscles is effected by way of the sacral ventral roots, selection in the resultant muscle action being effected by use of discriminating signal forms. Sphincter closure action is effected by use of a low intensity pulse train whereby the sphincter is stimulated but not the bladder and so incontinence is avoided. Bladder muscle action to cause micturation is effected by use of a higher intensity pulse train whereby both muscles are stimulated during each pulse train, but during each interruption the sphincter relaxes while the bladder remains contracted.

Abstract translation: 括约肌和膀胱肌肉通过电刺激进行泌尿控制是通过骶腹根进行的，通过使用鉴别信号形式来选择所产生的肌肉作用。 括约肌闭合作用是通过使用低强度的脉冲串来实现的，其中括约肌被刺激而不是膀胱，因此避免了尿失禁。 通过使用较高强度的脉冲串来实现膀胱肌肉作用，从而在每个脉冲串期间刺激肌肉，但是在每次中断期间，当膀胱保持收缩时，括约肌松弛。

Abstract: An implantable neurological prosthetic device comprises a plurality of electrodes for stimulating the striate cortex, a matrix of normally closed gates connected in one-to-one relationship with said electrodes, and a plurality of radio receivers tuned to predetermined frequencies and constituting at least two distinctive sets, each gate being connected for switching to an open state to energize the respective one of said electrodes by a unique group of at least two of said receivers from respectively different sets thereof. The receivers are themselves energizable by externally located respective transmitters conveniently positioned by a technique in which the transmitter tuned circuit is included as one arm in a bridge circuit balanced for maximum absorption by the respective receiver tuned circuit. This technique is more generally applicable to any implant provided with a tuned circuit.
