Cathlock Coupling Tool

Embodiments disclosed herein are directed to a tool configured to engage a cathlock and facilitate urging the cathlock axially on to a port stem within the confined, wetted environment of a tissue pocket. The tool can include a body defining a channel configured to receive the cathlock therein and a handle extending therefrom. The body can include an elongate opening communicating with the channel. The cathlock and/or portion of the catheter can pass through the elongate opening. Further, the elongate opening can allow the body to flex and grip the cathlock within the channel. In an embodiment, an axis of the handle can align with one of the first end or the second end of the body to facilitate either "pushing" or "pulling" the cathlock onto the port stem.
