Abstract
A needle having a first end, a second end, and a lumen extending within an interior of the needle, between the first end and the second end. A sleeve is engageable within an interior diameter or interior surface of the lumen. The sleeve includes a first end and a second end that are sized to reside within the first end of the lumen and the second end of the lumen, respectively. Ports extend between the first end and the second end of the sleeve. The ports have an inlet and an outlet sized to receive and route stimulator wires to areas within the epidural space of a spine.

(canceled)
An apparatus, comprising:
- a needle including a first end and a second end opposite the first end, the needle defining a lumen that extends within an interior of the needle between the first end and the second end, the lumen having an interior surface;
- and
- a sleeve engageable with at least a portion of the interior surface of the lumen, the sleeve including:
- a proximal end,
- a distal end opposite the proximal end, the distal end being sized to fit within the first end of the needle,
- a first port extending between the proximal end and the distal end, the first port having a first inlet at the proximal end and a first outlet at the distal end, the first port being configured to receive a first stimulator wire lead, and
- a second port extending between the proximal end and the distal end, the second port having a second inlet at the proximal end and a second outlet at the distal end, the second port being configured to receive a second stimulator wire lead.
