As used herein, “tunnel” refers to a duct, an opening, a void, a passage, or other channel in a body or structure of an apparatus, instrument, structure, part, bone, member, device, component, system, or assembly. In certain embodiments, a tunnel is narrower and longer than the tunnel is wide. A tunnel can have a variety of shapes and/or cross-sections and may be straight or include curves or bends. In certain embodiments, a tunnel may have a circular cross section. In certain embodiments, a tunnel may extend partially into, or wholly through a body or structure. Where a tunnel extends partially into a body or structure, the tunnel may also be referred to as an opening, a cave, or the like.
