1. An introducer system for use with a navigation probe having a navigation element and a navigation probe shaft having a diameter and terminating at a distal probe tip, the introducer system comprising an introducer having:
a sidewall extending along a longitudinal axis and forming an introducer passage extending from a proximal introducer end to a distal introducer end, the sidewall being larger, in a lateral direction that is orthogonal to the longitudinal axis, than the navigation probe shaft diameter;
a probe receptacle located at the distal introducer end, the probe receptacle extending along the longitudinal axis within the introducer passage from a proximal receptacle end to a distal receptacle end, the probe receptacle having an inner surface that tapers continuously from a first lateral size in the lateral direction at the proximal receptacle end to a second lateral size in the lateral direction at the distal receptacle end, the first lateral size being greater than the second lateral size;
wherein the inner surface is configured and dimensioned to receive the distal probe tip and restrict movement of the distal probe tip in the lateral direction, and the sidewall is configured and dimensioned to allow the navigation probe shaft to move in the lateral direction within the passage when the distal probe tip is positioned in the probe receptacle; and
wherein the inner surface comprises a proximal portion adjacent the proximal receptacle end having a first angle relative to the longitudinal axis, and an intermediate portion located distally from the proximal portion and having a second angle relative to the longitudinal axis, the second angle being less than the first angle.
