Abstract
Some embodiments of a medical anchor device include an elongate body coupled with deployable subcutaneous anchors to secure a catheter instrument (or other medical instrument) in place relative to a skin penetration point. In some circumstances, the elongate body may be in the form of catheter hub body, and the subcutaneous anchors can be deployed from the hub body by adjustment of a movable actuator. A locking member can interact with the actuator so as to retain the actuator in the deployed orientation during the medical procedure.
Claims20
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.

- 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.
