An apparatus and method for identifying a body member during a body intrusive procedure includes infrared light energy which is applied to the body member. Substantially visible infrared free light is introduced into the region. The body member is located by detecting the infrared light energy applied thereto. The infrared light energy may be applied to the body member via a light guide which is inserted into or placed in contact with the body member. In addition, a body member to be located may be illuminated from one side and the location of the illuminator detected by a probe on the other side of the body member.
