Needleless access connector facilitating instrument delivery to a catheter assembly

A needleless access connector, comprising:

• a body, comprising:
• a proximal end configured to couple to an instrument delivery device, the proximal end comprising a proximal opening;
• a distal end configured to couple to a peripheral intravenous catheter assembly, the distal end comprising a distal opening;
• and
• a lumen extending between the proximal end and the distal end;
• and
• an accordion valve disposed within the body between the proximal end and the distal end, wherein the accordion valve comprises an accordion portion, wherein in response to compression of the accordion portion and opening of the accordion valve, a straight pathway extending through the proximal end and the distal end is exposed such that an instrument of the instrument delivery device may move distally from the proximal end to the distal end through the straight pathway without bending;
• an anti-reflux valve disposed within the body between the proximal end and the distal end;
• and
• another anti-reflux valve disposed within the body between the proximal end and the distal end, wherein the lumen is closed between the distal opening of the distal end of the body and the proximal opening of the proximal end of the body.
