Claim 0:
1. An occlusion system implantable in a human or animal body, comprising:
a casing made of a biocompatible material;
an inflatable occlusive sleeve outside the casing, the inflatable occlusive sleeve being configured to surround an anatomical duct;
a reservoir filled with a fluid arranged within the casing, the reservoir comprising a fixed portion and a movable portion defining together a fluid volume of the reservoir;
a tubing fluidically coupling the reservoir to the inflatable occlusive sleeve;
an actuator mechanically coupled with the movable portion of the reservoir and configured to displace said movable portion relative to the fixed portion for adjusting the fluid volume of the reservoir, wherein the fluid volume adjustment moves fluid between the reservoir and the occlusive sleeve through the tubing;
a control unit configured to command the actuator based on a pressure to be applied by the occlusive sleeve onto the anatomical duct; and
at least one force sensor comprising one or several strain gauges in a mechanical connection with at least one of the actuator and the movable wall of the reservoir to measure a compressive and a traction force in a direction of displacement of the movable wall.
