(57) : A system to detect a position of a cannula may include a cannula, which may include a distal tip and an inner lumen. I N Also, the system may include an optical fiber, which may be disposed within the inner lumen of the cannula and may include a first Il C end, a second end, and a U-shaped portion disposed between the first end and the second end. The U-shaped portion may be at least N proximate the distal tip. Further, the system may include a light emitter, which may be coupled with the first end of the optical fiber, O and a light receiver, which may be coupled with the second end of the optical fiber. Moreover, the system may include an electronic ,-t processor. The electronic processor may be coupled with the light receiver and configured to detect a decrease in an intensity of light received at the light receiver.
