Abstract

L'invention concerne un appareil et une technique servant à réguler la fonction vésicale d'un patient par la stimulation combinée des racines sacrées ventrale et dorsale. Une électrode est implantée dans les nerfs sacrés moteurs, et une deuxième électrode est implantée dans les nerfs sacrés sensoriels. On stimule ces nerfs en utilisant des trains d'impulsions quasi-trapézoïdales pour activer et vider la vessie de manière sélective. Cette technique rend superflue l'opération de rhizotomie dorsale.
