1. A method for subcutaneously anchoring a catheter instrument, comprising:
inserting a distal catheter portion of a catheter hub body through a skin penetration point, wherein the catheter hub body provides fluid communication from an internal lumen to the distal catheter portion, the internal lumen extending longitudinally from a proximal end of the catheter hub body toward a distal end of the catheter hub body;
adjusting flexible anchors of a subcutaneous anchor mechanism from a non-deployed orientation to a deployed orientation in which the flexible anchors extend outwardly from the catheter hub body into a subcutaneous layer proximate to the skin penetration, wherein the flexible anchors are adjusted by moving an actuator longitudinally relative to the catheter hub body;
moving a locking device attached to the catheter hub body to releasably maintain the flexible anchors in the deployed orientation, the locking device movable from a first position in which the locking device abuts an external proximal end face of the actuator and a second position in which the locking device abuts with an external distal end face of the actuator.
