An apparatus includes a proximal portion and a distal portion attached to the proximal portion. The proximal portion includes a proximal surface. The proximal portion defines a first pathway and a second pathway that both extend distally from the proximal surface. The first pathway is dimensioned to receive a shaft while the second pathway is dimensioned to receive a navigation guidewire. The distal potion includes a distal tip terminating into a distal end. The second pathway extends from the proximal portion into the distal tip.
