A multipolar feedthrough filter capacitor assembly for an active implantable medical device includes a feedthrough filter capacitor including a first active electrode plate, a second active electrode plate and a plurality of ground electrode plates. A first portion of the sequence depends on fewer reference frames then a second portion of the sequence. The biasing portion is configured to provide an electrical connection between the at least one first and second contact portions and to resiliently move the at least one connecting element from a first position to a second position to provide a mechanical coupling force to the first and second objects. Therefore, the probing module can be replaced individually when probes are damaged or worn without replacing the whole probe head to reduce the fabrication cost of a multi-DUT probe head. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.
