1. A lead adapter for a patient treatment system, the lead adapter comprising:
a) a housing extending from a housing proximal end to a housing distal portion having a housing distal open end, wherein the housing has a plurality of inlets, each inlet being segregated from an immediately adjacent inlet by a housing intermediate wall;
b) a plurality of electrical contact assemblies residing in the housing, the plurality of electrical contact assemblies being electrically connected to a respective one of a plurality of electrical contact posts, wherein the plurality of electrical contact posts each have an exposed terminal portion residing in a respective one of the plurality of inlets; and
c) a header that is movably secured to the housing distal portion to selectively open and close the housing distal open end as the header is manipulated from a closed position to an open position and is further manipulated from the open position to the closed position, wherein the header has at least one longitudinally extending opening that is configured to receive a proximal end of an implantable lead,
d) wherein with the header in the open position, the proximal end of the implantable lead is movable into the longitudinally extending opening, and wherein the header is then manipulatable into the closed position to move an electrical contact of the implantable lead into contact with a respective one of the plurality of electrical contact assemblies electrically connected to a respective one of the plurality of electrical contact posts so that the electrical contact of the implantable lead is in electrical continuity with an exposed terminal portion of a respective one of the plurality of electrical contact posts.
