Methods and apparatuses for controlling bladder discharge in a patient are described. The method includes coupling a first electrode to a sacral ventral root of the patient and coupling a second electrode to a sacral dorsal root of the patient. The method may be applied to spinal cord injured patients without dorsal root section.

Combined stimulation of ventral and dorsal sacral roots for control of bladder function

A device for coupling nerve cuff electrodes for stimulating nerves to a signal source for applying electrical signals for activation. The device comprises a carrier plate composed of a non-conductive material which contains a series of grooves for receiving selected nerve trunks. On either side of each groove is located a slot along the length of the groove, and a plurality of contacts are embedded within each groove. The contacts are releasably coupled to a power source which supplies a stimulating signal to the nerves. A spiral cuff electrode is wrapped through the slots to secure the nerve within the contact and provide for electrical conduction.
