Abstract
Appareil servant à guider un instrument médical vers un endroit cible prédéterminé situé à l'intérieur des tissus périurétraux (250) d'un patient. Cet appareil dirige l'instrument le long d'un trajet prédéterminé par rapport à l'urètre du patient et limite la pénétration de l'instrument à une profondeur prédéterminée. La forme de réalisation décrite concerne un appareil permettant d'implanter des prothèses gonflables (220) à l'intérieur des tissus périurétraux pour effectuer la coaptation de l'urètre (250) et ainsi pallier l'incontinence. Cette invention concerne également un procédé permettant d'effectuer la coaptation de l'urètre d'un patient, selon lequel on forme deux canaux fonctionnels dans les tissue périurétraux puis on introduit dans chacun d'eux une prothèse gonflable (220). On ne gonfle les prothèses (220) qu'après avoir formé les deux canaux fonctionnels et de préférence qu'après avoir positionné les deux prothèses (220) à l'intérieur de leur canal respectif. Les prothèses gonflées (220) bloquent l'urètre (250) et produisent sa coaptation.
