A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending from a distal end of the catheter adapter. The catheter system may include a needle assembly, which may include a barrel, a needle hub slidably disposed within the barrel, and an introducer needle secured within the needle hub and extending through the catheter. The needle assembly may also include a stop surface coupled to the barrel and an activation latch. The activation latch may be slidable from a first position to a second position with respect to the barrel. In response to the activation latch being in the first position, the stop surface may contact the activation latch and depression of the activation latch may be prevented. In response to sliding of the activation latch from the first position to the second position, the stop surface may not contact the activation latch, which may depress.
