An artificial sphincter to be implanted in a urethra, for treating patients suffering from urinary incontinence, includes a container configured to be connected to a wall of a urethra, inside or outside it, a valve unit housed within the container and configured to move from a release configuration to a block configuration and vice-versa. An actuation magnet is movably (rotatably or slidably) arranged between a first and a second position in the container, and is connected to the valve unit such that a predetermined (rotation or translation) movement of the actuation magnet from a first towards a second position, or from the second towards the first position, under the effect of an external manoeuvre magnet, brings the valve unit from the release configuration to the block configuration, where the valve is stably maintained, and from the block configuration to the release configuration, where the valve is stably maintained.

A system for the controlled administration of a substance by means of an infusion device implanted in the human body is described. The system has an implantable unit for detecting a shortage or an excess of such substance or a physiological parameter correlatable to the shortage or excess of such substance, an infusion group of this substance implantable in the peritoneal cavity and having a central control unit for processing data received from the detection unit, and energy storage means to power such infusion group. The system also has a carrier of such substance adapted to be ingested, and a refilling device for refilling the infusion group with such substance.
