A guide member system (10) includes a guide member (50, 200, 400) a light source (302, 502), and a detector (306, 506). The guide member comprises at least one illumination fiber (56, 208, 407, 408). The at least one illumination fiber distally transmits the light projected by the light source from the proximal end of the guide member to the distal end of the guide member. The distal end of the guide member is projects the distally transmitted light. The distal end of the guide member receives light projected from the distal end of the guide member and reflected back toward the distal end of the guide member. The at least one illumination fiber proximally transmits the reflected light from the distal end of the guide member to the proximal end of the guide member. The proximal end of the guide member projects the proximally transmitted light toward the detector. The detector detects the proximally transmitted light. |
