Title
(EN) SYSTEM AND METHOD FOR ELECTRICAL STIMULATION OF ANORECTAL STRUCTURES TO TREAT URINARY DYSFUNCTION
(FR) SYSTÈME ET PROCÉDÉ POUR STIMULATION ÉLECTRIQUE DE STRUCTURES ANORECTALES EN VUE DU TRAITEMENT D'UN DYSFONCTIONNEMENT URINAIRE
Abstract
(EN)
A system and method for treating anorectal and/or genitourinary dysfunction includes implanting, in a minimally invasive manner, an electro-medical device for stimulation of two or more anatomical or histological structures of the anorectal region and/or genitourinary region. Electrodes operably connected to the device are positioned proximate the target anatomical or histological structures. The device provides either the same or different stimulation algorithms to each anatomical or histological structure, which may be the same or different. The varied stimulation parameters, such as pulse width, pulse amplitude, and pulse frequency, are defined such that after an application of the electrical pulses, an abdominal leak pressure, an abdominal leak volume, or a urine volume increases or a number of incontinent episodes or a mean incontinence volume per episode decreases relative to said parameters prior to the application of the electrical pulses.
(FR)
L'invention concerne un système et une méthode destinés à traiter un dysfonctionnement anorectal et/ou génito-urinaire qui impliquent l'implantation, de manière aussi peu invasive que possible, d'un dispositif électromédical pour stimuler au moins deux structures anatomiques ou histologiques de la région anorectale et/ou génito-urinaire. Des électrodes fonctionnellement reliées au dispositif sont placées à proximité des structures anatomiques ou histologiques cibles. Le dispositif délivre des algorithmes de stimulation identiques ou différents à chaque structure anatomique ou histologique, qui peut être la même ou pas. La variation des paramètres de stimulation, par exemple la durée d'impulsion, l'amplitude d'impulsion et la fréquence d'impulsion, est définie de telle sorte qu'après une application des impulsions électriques, la pression de fuite abdominale, le volume de fuite abdominale ou le volume d'urine augmente ou le nombre d'épisodes d'incontinence ou le volume moyen d'incontinence par épisode diminue par rapport auxdits paramètres préalablement à l'application des impulsions électriques.
