Abstract

L'invention concerne un régulateur de débit (22) implantable servant à réguler le débit d'un médicament le long d'une voie de distribution (14) de médicament entre une source de médicament et un site de traitement à l'intérieur d'un sujet. Ce régulateur de débit comprend un élément de dérivation (24) mobile et un élément d'actionnement. L'élément de dérivation (24) mobile est fonctionnellement relié à la voie de distribution (14). L'élément d'actionnement peut être actionné pour déplacer l'élément de dérivation (24) entre au moins une position de premier mode dans laquelle l'élément de dérivation (24) empêche l'écoulement à travers la voie de distribution (14) (la voie de distribution est 'fermée') et une position de second mode dans laquelle l'élément de dérivation (24) est placé de façon à permettre l'écoulement à travers la voie de distribution (14) (la voie de distribution est 'ouverte'). Lorsque l'élément d'actionnement est alimenté en énergie, il est actionné et déplace l'élément de dérivation (24) de sa position de premier mode, ou position 'fermée', normalement sollicitée, qui est également une position de sécurité, à sa position de second mode, ou position 'ouverte'. Dans la position 'ouverte', le médicament est acheminé jusqu'à des sites cibles, généralement à partir d'une réserve de médicament située à l'intérieur du régulateur.
