At times, a tip of a peripherally inserted central catheter (“PICC”) or central venous catheter (“CVC”) can move, becoming displaced from an ideal position in a patient's superior vena cava (“SVC”). A clinician believing such a PICC or CVC has displaced typically checks for displacement by chest X-ray and replaces the PICC or CVC if necessary. Because X-rays expose patients to ionizing radiation, medical devices such as PICCs and CVCs are being developed with integrated optical-fiber stylets for clinicians to easily and safely check for displacement thereof by way of shape sensing with the optical-fiber stylets. However, in order for the clinicians to check for displacement, the PICCs or CVCs, which are sterile as provided, need to be optically and electrically connected to non-sterile capital equipment without compromising sterile conditions. Therefore, there is a need for a connection system that allows for single-use medical devices such as the foregoing PICCs and CVCs to be optically and electrically connected to non-sterile capital equipment without compromising sterile conditions.
