An instrument advancement device comprising:

• an access connector configured to be connected to a vascular access device;
• a primary lumen in fluid communication with the access connector;
• an instrument received within the primary lumen and having a retracted position where a distal end of the instrument is positioned within the primary lumen or the access connector, and an advanced position where the distal end of the instrument extends beyond a distal end of the primary lumen and the access connector;
• 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 advanced position;
• and
• a lumen seal received within the primary lumen and connected to the instrument, wherein the lumen seal defines a space between the lumen seal and the primary lumen when the instrument is in the retracted portion, and wherein the lumen seal engages the primary lumen when the instrument is in the advanced position.
