摘要：
A catheter device to visually identify a blood vessel may include a cannula. The cannula may include a distal tip, an elongated tubular shaft, and an inner lumen formed by the elongated tubular shaft. The cannula may also include an optical fiber, which may be disposed within the inner lumen of the cannula. The optical fiber may include a distal end and a proximal end. The optical fiber may be configured to emit light from the distal end.
