Stimulation therapy lead trial cable connector

A stimulation therapy lead connector configured to facilitate electrical and mechanical connectivity between at least one stimulation lead and an external pulse generator, the at least one stimulation lead having a distal end with a plurality of stimulation electrodes and a proximal end with a corresponding plurality of terminal contact electrodes, the proximal end having an outer diameter and an inner diameter, wherein the distal end of the at least one stimulation lead is implantable in a patient using a guide wire inserted into the at least one stimulation lead from the proximal end to guide the distal end to a target tissue area, the stimulation therapy lead connector comprising:

• a housing;
• at least one cam lock assembly at least partially enclosed in the housing, the at least one cam lock assembly comprising a cam knob rigidly coupled to a cam shaft, the cam knob and the cam shaft having a longitudinal channel along a common axis, the longitudinal channel having at least a portion with a diameter sized to accommodate the outer diameter of the proximal end;
• a plurality of cantilevered conductive spring contacts mounted to a substrate securely disposed in the housing adjacent to the at least one cam lock assembly, the cantilevered conductive spring contacts operative to make electrical contact with the plurality of terminal contact electrodes of the proximal end after the proximal end is guided into the longitudinal channel using the guide wire inserted through a guide wire slot in the housing that is aligned with a longitudinal slit along the longitudinal channel when the cam knob is turned in a first direction and the at least one cam lock assembly is locked in a position by turning the cam knob in a second direction opposite to the first direction such that the longitudinal slit of the longitudinal channel is no longer aligned with the guide wire slot in the housing;
• and
• a plurality of conductors electrically connected to the plurality of cantilevered conductive spring contacts, the plurality of conductors encased in a cable having an interface for mating with an interface receptacle of the external pulse generator.
