Catheter system with guidewire advancement element

1. 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.

2. The method of claim 1 , wherein the wing is gripped with the first hand at a same time as the guidewire advancement element is gripped with the second hand.

3. The method of claim 1 , wherein the housing comprises a grip, wherein the proximal end of the introducer needle is coupled to the grip and secured within the housing, wherein gripping the wing of the integrated catheter adapter comprises sandwiching the wing and the grip between a thumb and index finger of the first hand of the user, wherein the wing and the grip are sandwiched between the thumb and the index finger of the first hand of the user at a same time as the guidewire advancement element is gripped with the second hand.

4. The method of claim 1 , wherein the wing is a first wing, wherein the housing comprises a thumb tab and a second wing opposite the first wing, wherein gripping the first wing comprises placing a first finger of the first hand on an upper surface of the first wing,

further comprising, at a same time as the first wing of the integrated catheter adapter is gripped with the first hand and the guidewire advancement element is gripped with the second hand, gripping the second wing and the thumb tab by placing a second finger of the first hand on an upper surface of the second wing and a thumb of the first hand on the thumb tab.

5. The method of claim 1 , wherein the intravenous catheter system further comprises a grip, wherein the introducer needle is coupled to the grip, further comprising moving the guidewire advancement element or the grip along the slot in a proximal direction, wherein in response to moving the guidewire advancement element along the slot in the proximal direction, the guidewire and the introducer needle move towards the proximal end of the housing.

6. The method of claim 5 , wherein in response to moving the guidewire advancement element or the grip along the slot in the proximal direction such that the guidewire is in the retracted position and the introducer needle is shielded within the housing, the housing is configured to uncouple from the integrated catheter adapter.
