A sphincter treatment apparatus has an introducer including a distal portion. An expandable device includes a plurality of arms. Each arm of the plurality has a distal section and a proximal section. Each of distal sections of the arm are coupled and each of the proximal sections of the arm are coupled to the introducer distal portion. The expandable device is configured to at least partially dilate a sphincter in a deployed state. An energy delivery device is introduceable from the introducer into a selected site of the sphincter. The energy delivery device is configured to deliver sufficient energy to reduce a frequency of relaxation of the sphincter.

Un appareil de traitement du sphincter est constitué d'un introducteur comprenant une partie distale. Un dispositif déployable comprend plusieurs bras présentant chacun une partie distale et une partie proximale. Chaque partie distale des bras est accouplée et chaque partie proximale des bras est accouplée à la partie distale de l'introducteur. Le dispositif déployable est conçu pour dilater au moins partiellement un sphincter, lorsqu'il est en position de déploiement. Un dispositif d'alimentation en énergie est introduit par le moyen introducteur dans un site sélectionné du sphincter et est conçu pour envoyer suffisamment d'énergie et réduire la fréquence de relâchement du sphincter.
