Patent ID: 7753889

Claim:
An anchor sleeve device, comprising: an elongate body that defines at least one working channel extending from a proximal portion to a distal tip portion; a subcutaneous anchor mechanism coupled to the elongate body, the subcutaneous anchor mechanism having one or more flexible anchors that extend away from an outer wall of the elongate body when in a deployed orientation with the distal tip portion of the elongate body in a subcutaneous layer; a subcutaneous cuff device arranged along an outer surface of the elongate body at a position distally of the one or more flexible anchors, the subcutaneous cuff device comprising a biocompatible material to receive ingrowth of bodily tissue when disposed in the subcutaneous layer, wherein the working channel of the elongate body is sized to receive a catheter having a catheter tip, wherein when the catheter is distally advanced through the working channel, a cuff-to-tip distance between the subcutaneous cuff device and the catheter tip is adjusted; and a locking device that releasably affixes to the catheter when the catheter is received in the working channel, wherein the locking device is shiftable to compress at least a portion of an outer surface of the catheter when the catheter is received in the working channel, wherein the locking device affixes the catheter in response to the one or more flexible anchors being adjusted to the deployed orientation.
