Abstract
This document discusses trajectory guides that include an instrument guide with at least one lumen angled with respect to an orthogonal or other through-axis. In one example, patterned lumens on the instrument guide provide a mirror image pattern of trajectory axes intersecting a target plane. In another example, height adjustment of the instrument guide extends these or other targeting techniques to a three-dimensional volume. This document also describes a method of manufacturing such an instrument guide, which is also applicable to manufacturing an instrument guide providing parallel lumens.
