Midline catheter placement device

A method of inserting a catheter, comprising:

• providing a catheter insertion device, comprising:
• a housing;
• a needle extending from a distal end of the housing;
• an actuator assembly including an actuator button and an actuator body;
• a catheter assembly disposed coaxially over the needle, comprising:
• a catheter supported by a catheter hub;
• and
• a safety assembly;
• and
• a lockout device transitionable between a locked position and an unlocked position, the locked position permitting movement of the catheter relative to the needle and inhibiting advancement of the catheter in a stepwise manner;
• actuating the actuator button with the lockout device in the locked position to move the catheter relative to the needle;
• transitioning the lockout device from the locked position to the unlocked position;
• inserting the needle into a patient to access a vasculature thereof;
• and
• actuating the actuator button from a first position to a second position to advance the catheter in the stepwise manner relative to the needle.

A method of advancing a catheter over a needle, comprising:

• providing a catheter placement device, comprising:
• a housing including a plurality of housing tabs and a needle extending from a distal end thereof;
• a catheter assembly including a catheter disposed coaxially over the needle and engaging a first housing tab of the plurality of housing tabs;
• an actuator assembly configured to move between a first position and a second position to advance the catheter assembly from the first housing tab to a second housing tab of the plurality of housing tabs adjacent to the first housing tab;
• and
• a lockout device transitionable between a locked position and an unlocked position, the locked position restricting movement of the catheter assembly between the first housing tab and the second housing tab, the unlocked position permitting movement of the catheter assembly between the first housing tab and the second housing tab;
• actuating the actuator button with the lockout device in the locked position to move the catheter relative to the needle while preventing the catheter assembly from advancing from the first housing tab to the second housing tab;
• transitioning the lockout device from the locked position to the unlocked position;
• inserting the needle into a patient to access a vasculature thereof;
• and
• actuating the actuator button from the first position to the second position to advance the catheter assembly from the first housing tab to the second housing tab.
