1. A lead extension for electrically coupling to at least one implantable electrical stimulation lead, the lead extension comprising:

  • at least one lead extension body having a first end portion and an opposing second end portion;

    a plurality of terminals disposed along the first end portion of the at least one lead extension body;

    a lead extension connector disposed along the second end portion of the at least one lead extension body, the lead extension connector configured and arranged to mechanically receive a proximal end portion of at least one electrical stimulation lead, the lead extension connector comprisinga first connector body defining a pin channel,a second connector body comprising a pin, wherein a dimension of the pin is greater than a corresponding dimension of the pin channel,at least one lead channel defined within the first and second connector bodies and configured and arranged to receive the at least one electrical stimulation lead, anda plurality of connector contacts disposed within the first connector body and configured and arranged to make electrical contact with terminals disposed on the at least one electrical stimulation lead when the at least one electrical stimulation lead is received in the at least one lead channel,wherein the pin channel is configured and arranged to receive the pin and, when the pin is received in the pin channel, compress a portion of the first connector body against the at least one electrical stimulation lead in the at least one lead channel to facilitate retention of the at least one electrical stimulation lead within the at least one lead channel; and

    a plurality of conductors extending along the at least one lead extension body and electrically coupling the connector contacts in the lead extension connector to the terminals.
