Connector, and method

A connector configured to be anchored in a first object with thermoplastic material, the connector defining a proximodistal axis and comprising:

• a plate portion extending around the proximodistal axis and having a proximal face and a distal face, the proximal face being adapted for a tool to be pressed against the proximal face;
• an attachment structure accessible from the proximal side of the plate portion and/or an interaction element comprising a sensor and/or actuator;
• an anchoring skirt protruding distally from the plate portion towards distally and radially outwardly, whereby an outer pocket open towards radially outwardly is formed between the distal face of the plate portion and a proximal face of the anchoring skirt, and an inner pocket open towards distally is formed radially inwardly of the anchoring skirt;
• wherein the connector is capable of being anchored with respect to the first object by causing a tool to press the connector against the first object while the anchoring skirt is in physical contact with the first object and while mechanical energy is coupled into the connector until thermoplastic material of the first object flows relative to the connector and is caused to flow into the outer pocket and the inner pocket.
