Anchoring a medical instrument
First Claim
Patent Images
1. A medical anchoring system, comprising:
- a catheter device that provides fluid communication from an internal lumen of an external catheter portion to a distal catheter portion that is insertable through a skin penetration point, the internal lumen extending longitudinally from a proximal end of the external catheter portion toward a distal end of the external catheter portion;
means for subcutaneously anchoring the external catheter portion, the subcutaneously anchoring means being movably coupled to the external catheter portion to adjust between a non-deployed orientation and a deployed orientation in which the subcutaneously anchoring means extend outwardly from the external catheter portion into a subcutaneous layer proximate to the skin penetration point;
means for actuating the subcutaneously anchoring means to shift from the non-deployed orientation to the deployed orientation, the actuating means being externally movable relative to the external catheter portion; and
means for locking the subcutaneously anchoring means in the deployed orientation after the actuating means shifts the subcutaneously anchoring means to the deployed orientation, the locking means being movable relative to the subcutaneously anchoring means and relative to actuating means from a first position to a locking position in which the locking means resists movement of the actuating means, wherein in the locking position the locking means abuts with the actuating means so as to lock the subcutaenously anchoring means in the deployed orientation.

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.
