Abstract
A lead connection system includes a connector housing. A plurality of lead retainers disposed in the connector housing are configured and arranged to removably attach to a proximal end of one of a received plurality of leads. The plurality of lead retainers include at least one of a slidable drawer and at least one pivotable hinged panel. A plurality of connector contacts are configured and arranged for making electrical contact with one or more of the terminals of one or more of the plurality of received leads. A single connector cable has a distal end that is electrically coupled to the plurality of connector contacts and a proximal end that is configured and arranged for insertion into a trial stimulator. A cable connector is electrically coupled, via the connector contacts, to at least one terminal of each of the received plurality of leads.
