Patent ID: 8137323

Claim:
A system for subcutaneously anchoring a catheter instrument, comprising: a catheter hub body that is connected to first and second proximal external lines and connected to a distal catheter line which is insertable through a skin penetration point, wherein the catheter hub body provides fluid communication between the first proximal external line and a first lumen of the distal catheter line and provides fluid communication between the second proximal external line and a second lumen of the distal catheter line; a pair of subcutaneous anchor elements that are adjustable between a non-deployed orientation in which the subcutaneous anchor elements are housed inside the catheter hub body and a deployed orientation in which free ends of the subcutaneous anchor elements extend outwardly away from the catheter hub body in a subcutaneous layer proximate to the skin penetration point; an actuator to shift the flexible anchors from the non-deployed orientation to the deployed orientation; and a locking device to releasably maintain the pair of subcutaneous anchor elements in the deployed orientation, wherein the first and second proximal external lines, at least a portion of the actuator, and the locking device are configured to remain external to the skin penetration point when the distal catheter line and the pair of subcutaneous anchor elements are inserted through the skin penetration point.
