Abstract

A catheter insertion device is provided for positioning and inserting a catheter, particularly a midline catheter, into a patient. The insertion device includes an actuator assembly movable relative to a housing for deploying the catheter over the needle. Stepwise movement of the actuator incrementally advances the catheter assembly, including the catheter, over the introducer needle. An indexing finger of the catheter assembly engages the actuator body during distal advancement of the actuator and deflects as the actuator moves proximally. The device further includes a lockout device, such as a button, collar, slider, or tab, that allows movement of the catheter relative to the needle but prevents advancement of the catheter into the first stage of incremental movement.
