A lead introducer includes a needle assembly and a hub assembly. The needle assembly includes an outer needle defining an outer-needle open channel and an inner needle disposed within the outer needle and defining an inner-needle open channel. The inner needle is rotatable independently within the outer needle to transition the needle assembly between open and closed positions. When in the open position, the inner-needle open channel is rotationally-aligned with the outer-needle open channel to form a separation channel for separating a lead from the needle assembly. When in the closed position, the inner-needle open channel is rotationally-offset from the outer-needle open channel to form a lead lumen. The hub assembly includes an outer-needle hub coupled to the outer needle and an inner-needle hub coupled to the inner needle.
