An occlusive apparatus (10) and method for reversibly occluding fluid conveying vessels in the body. In one embodiment, the occlusive apparatus includes an occlusive member (12) adapted for at least partially encircling a vessel, with the occlusive member including an intrinsic spring force therein for exerting an occluding pressure on the vessel while the occlusive member at least partially encircles the vessel. A control mechanism (16) is operatively connected to the occlusive member, with the control mechanism being arranged and configured to counteract the intrinsic spring force of the occlusive member and thereby remove the occluding pressure on the vessel while the occlusive member is at least partially encircling the vessel.
L'invention porte sur un obturateur (10) et un procédé réversible d'occlusion de canaux transportant des liquides corporels. Dans une exécution l'appareil comporte un élément d'obturation (12) conçu pour entourer au moins partiellement un vaisseau et exerçant sur ledit vaisseau une force intrinsèque sous l'effet d'un ressort lorsque l'obturateur entoure au moins partiellement ledit vaisseau. L'invention porte également sur un mécanisme de commande (16) fonctionnellement lié à l'élément d'occlusion, conçu pour relâcher la pression, et configuré pour contrecarrer la force intrinsèque de l'obturateur, et par là, à relâcher la pression occlusive sur le vaisseau lorsque l'obturateur entoure au moins partiellement le vaisseau.
