1. A system comprising:

  • an imaging apparatus that comprises;

    a light source that emits at least light having one or more wavelengths in the range of about 700 nanometers to about 2,500 nanometers;

    a camera that is (a) sensitive to light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers, and (b) so positioned relative to the light source as to receive light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers that has been (i) emitted from the light source, and (ii) reflected from a target;

    a filter that attenuates light having a wavelength shorter than 700 nanometers and is so positioned as to (i) filter light emitted from the light source, and/or (ii) filter light reflected from the target before it is received by the camera;

    a processor that forms an image signal based at least in part upon signals indicative of the light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers that is sensed by the camera; and

    a display screen so coupled to the processor as to receive the image signal and to display an image; and

    an access device that comprises a hollow, stiff, steel needle having an outer surface, at least a portion of which outer surface is (a) coated with a coating comprising at least one of (i) titanium nitride, (ii) gold, and (iii) a metal oxide, and/or (b) irregularized.
