Lead end having slotted member

A method of making a lead, the method comprising:

• connecting a plurality of elongated electrical conductors to a plurality of electrical elements;
• loading the plurality of conductors and the plurality of electrical elements onto a slotted member, the slotted member having a plurality of slots extending along at least a portion of the slotted member, the plurality of conductors being placed within the plurality of slots during the loading;
• positioning the plurality of electrical elements at different longitudinal locations along the slotted member based on a plurality of positioning features, the plurality of positioning features within the plurality of slots;
• and
• injecting polymer fill to contact and cover at least a portion of the slotted member and define an exterior surface of a lead body, the polymer fill filling at least some portions of the plurality of slots, an exterior surface of a lead body being defined by the injected polymer fill and exposed portions of the plurality of electrical elements.
