Closed system flexible vascular access device sensor deployment system

A sensor deployment system for a vascular access device, the system comprising:

• a primary lumen;
• a deployment connector configured to be connected to at least one of a luer connector, a needle-free connector, and a catheter adapter, the deployment connector attached to the primary lumen;
• an instrument at least partially received within the primary lumen, the instrument comprising a sensor, the instrument having a retracted position where a distal end of the instrument is positioned within the primary lumen or the deployment connector and an extended position where the distal end of the instrument extends beyond a distal end of the primary lumen and the deployment connector;
• a communication device configured to transmit data from the sensor;
• and
• an advancement member configured to be grasped by a healthcare technician, wherein movement of the advancement member moves the instrument between the retracted position and the extended position, wherein the advancement member is configured to move along an outer surface of the primary lumen, and wherein the advancement member is entirely positioned outside of the primary lumen.
