Abstract:
1. An anchor device for releasably securing to an external portion of a catheter while another portion of the catheter occupies a skin penetration point, the anchor device comprising: first and second anchors each having a longitudinal shaft portion and a flexible subcutaneous tine configured to be deployed through the skin penetration point and into a subcutaneous region along an underside of a skin layer; and a retainer base to releasably secure with the external portion of the catheter, the retainer base being in a folded condition about a longitudinal fold axis of the retainer base prior to deployment of the flexible subcutaneous tines through the skin penetration point such that the flexible subcutaneous tines are positioned generally adjacent to each other and oriented to extend in substantially the same direction, wherein the longitudinal shaft portion of the first anchor is positioned on an opposite side of the longitudinal fold axis from the longitudinal shaft portion of the second anchor, and wherein the longitudinal shaft portion of each of the first and second anchors extends distally in a longitudinal direction from a distalmost end of the retainer base, wherein the retainer base is adjustable to a non-folded condition about the longitudinal fold axis of the retainer base after deployment of the flexible subcutaneous tines through the skin penetration point so that the flexible subcutaneous tines are in an anchored position in which the flexible subcutaneous tines extend generally away from one another.
