Implantable Medical Device with Multiple Electrode Lead and Connector with Central Fastener

An implantable medical apparatus comprising

• an electrical device having a case and a plurality of electrical contacts on said case,
• a lead having a distal end and a proximal end and carrying a plurality of electrical conductors,
• a connector coupled to a proximal end of said lead, said connector having a central bore a plurality of electrical contacts distributed around said bore, each of said contacts being electrically connected to an electrical conductor in said lead and being spatially arranged to contact one of said electrical contacts on said case, and
• a fastener coupling said connector to said electrical device, said fastener extending through said bore in said connector, and
• a plurality of connector seals, each connector seal configured to surround an electrical contact on said case and an electrical contact on said connector when said connectors are in contact with each other.
