Catheter system with guidewire advancement element

A method of intravenous catheter insertion into vasculature of a patient, comprising:

• gripping, with a first hand of a user, a wing of an integrated catheter adapter of an intravenous catheter system, wherein the intravenous catheter system comprises:
• the integrated catheter adapter having the wing extending outwardly from a right side of a body of the integrated catheter adapter, wherein the integrated catheter adapter further comprises a side port;
• a housing coupled to a proximal end of the integrated catheter adapter, the housing having a body extending along a longitudinal axis, a proximal end, a distal end, and a slot, wherein a central plane of the housing extends along the longitudinal axis to divide a left side of the body of the housing from a right side of the body of the housing, wherein the slot is disposed on the left side and extending through the body of the housing from an interior of the body of the housing to an exterior of the body of the housing;
• an introducer needle having a proximal end, a distal tip, and a needle lumen extending between the proximal end and the distal tip of the introducer needle, wherein the proximal end of the introducer needle is secured within the housing;
• a guidewire disposed within the needle lumen;
• and
• a guidewire advancement element coupled to the guidewire and extending through the slot and moveable along the slot in a distal direction to move the guidewire from a retracted position to an advanced position, wherein the guidewire extends beyond the distal tip of the introducer needle when the guidewire is in the advanced position, wherein the guidewire advancement element is disposed on the left side of the housing;
• gripping, with a second hand of the user, the guidewire advancement element;
• and
• moving the guidewire advancement element in the distal direction to move the guidewire to the advanced position with the second hand.
