Abstract:
1. An anchor sleeve device, comprising: an elongate body that defines at least one working channel extending from a proximal opening to a distal tip opening so as to receive a catheter; a subcutaneous anchor mechanism coupled to the elongate body, the subcutaneous anchor mechanism having one or more flexible anchors that extend outwardly away from a wall of the elongate body when in a deployed orientation in a subcutaneous layer adjacent to a skin layer, the flexible anchors coupled to a slidable internal member nonrotatably mounted in the elongate body such that a distal end of the slidable internal member remains housed inside to the elongate body, wherein each of the flexible anchors extends outwardly from the slidable internal member along a longitudinal convex curvature toward a free end; a first actuator that is adjustable relative to the elongate body so as to shift the flexible anchors to the deployed orientation, the proximal opening of the elongate body being positioned proximally of a proximal end of the first actuator; a locking device that releasably engages to the catheter when the catheter is received in the working channel; and a second actuator that is positioned directly adjacent to the first actuator, the second actuator being adjustable relative to the elongate body so as to urge the locking device to compress at least a portion of an outer surface of the catheter when the catheter is received in the working channel, wherein a distal end of the locking device remains generally fixed while the second actuator is adjusted to urge the locking device to compress said at least a portion of the outer surface of the catheter when the catheter is received in the working channel.
