Abstract
An optical spectroscopic injection needle assembly may include an injection needle, a light source, a spectrometer, a computer and an indicator. The injection needle may include a hollow outer needle, a hollow inner needle, a pair of fiber optical fibers, an inner catheter, an outer catheter, an inner hub, and an outer hub. A proximal end of the outer needle may be fixedly mounted within a distal end of the inner catheter. A distal end of the inner hub may be fixedly mounted on a proximal end of the inner catheter. The inner needle and distal ends of the optical fibers may be positioned within the outer needle. The inner needle and the outer needle may be slidably mounted within the outer catheter to permit the outer needle to be selectively extended or retracted from a distal end of the outer catheter.
