Abstract: The invention relates to a medical device comprising: —a sealed casing (1), suited to being implanted in the body of a human or animal patient, —an inflatable element (3), —a fluidic circuit comprising a fluid reservoir (5) having a variable fluid volume and arranged inside the casing with a tube (2) between the reservoir and the inflatable element, —an actuator arranged inside the casing to selectively vary the volume of fluid in the reservoir, —a control unit (100) configured to control the actuator, —at least one sensor suited to measuring an absolute gauge pressure of the fluid in the fluidic circuit, a force exerted on the reservoir, a gas pressure inside the casing, an atmospheric pressure or a value relating to an altitude of the patient, the control unit (100) being configured so as: —on the basis of a measurement from said sensor while the actuator is inactive, to detect a differential between a value relating to an altitude of the patient and a reference value, and—as a function of said differential

Abstract: The invention relates to an assembly formed by a medical device (1) adapted to be implanted in a human or animal body and by packaging, wherein: te medical device comprises a housing (11) that encloses a fluid reservoir (13) and a fluid outlet (12) forming a fluid connection between the reservoir and a volume outside the housing; the packaging includes a tank (2) comprising a bottom (20), a side wall (21), an upper face opposite the bottom in a vertical direction, and an opening configured to fill the tank with a biocompatible fluid, the bottom (20) of the tank extending in a horizontal plane perpendicularly to the vertical direction; at least one of the bottom, the side wall and the top face comprises a first holding element (201) adapted to hold the housing in the tank, the housing (11) being held in the tank (2) by said first holding element (201) such that the reservoir is located between the bottom of the tank and the fluid outlet, said fluid outlet being arranged below the opening such that the fluid ou

Abstract: The invention relates to a method for draining a medical device (1) adapted to be implanted in a human or animal body, said medical device comprising a housing (11) that encloses a fluid reservoir (13), and a fluid outlet (12) that forms a fluid connection between the reservoir and a volume outside the housing, the method involving: —providing the device in packaging comprising a tank (2), the housing being held in the tank in a position in which the reservoir is located between the bottom of the tank and the fluid outlet; —filling the tank (2) with a biocompatible fluid such that a zone of the packaging which lies outside the medical device and is in fluid connection with the fluid outlet of the tank is immersed in the fluid; —draining the medical device and filling the reservoir (13) with the biocompatible fluid.
