Methods, devices and systems for improving pelvic floor dysfunction in a patient suffering therefrom by electrically modulating neural tissue in a minimally invasive fashion using an electrical microstimulator are provided. Methods include inserting an electrical microstimulator having a re-deployable fixation member through skin of a patient's leg and advancing the electrical microstimulator through the skin along tissue of a surgical pathway to an area of the patient's leg. A target implant site can be identified that is above deep fascia and below the skin and that is adjacent to a target nerve associated with pelvic floor function. The electrical microstimulator can be anchored to the target implant site via the re-deployable fixation member or re-positioned, if necessary. A therapy electrical signal can be delivered to the target nerve from the target implant site.L'invention concerne des procédés et des dispositifs pour améliorer un dysfonctionnement du plancher pelvien chez un patient souffrant de ce dysfonctionnement par une modulation électrique du tissu nerveux d'une manière minimalement invasive à l'aide d'un microstimulateur électrique.
