System for protecting a sensor for a force measurement and implantable occlusion device comprising such a system for protecting the sensor

A system for protecting a force measurement sensor comprising:

• the force measurement sensor, designed to measure at least one force exerted along a longitudinal axis of the force measurement sensor, wherein said at least one force comprises a tractive force and/or a compressive force, said force measurement sensor being designed to be made integral with a moveable part of a fluid reservoir, and
• a pre-strained elastic element arranged to bias the force measurement sensor in a direction opposite to said exerted force, said elastic element being deformable in a direction of the exerted force so as to protect the force measurement sensor from at least one compressive or tractive force greater than a threshold.
