Midline Catheter Placement Device

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 with respect to a housing for deploying the catheter over a needle. A step-wise movement of the actuator advances a catheter assembly, including the catheter, in stages 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 is moved proximally. The device further includes a lockout device such as a button, collar, slider, or tab, which allows movement of the catheter relative to the needle but prevents advancement of the catheter to the first stage of the step-wise movement.
