1. A method of using a catheter anchor device, comprising:
- advancing a catheter though a skin opening;
directing an anchor device toward the skin opening that is occupied by a portion of the catheter, the anchor device comprising;
a retainer body to releasably couple to an external portion of the catheter arranged outside the body, and first and second anchors extending distally of a distalmost face the retainer body;
inserting the first and second anchors through the same skin opening that is occupied by the catheter so that at least a portion of the first and second anchors are deployed in a subcutaneous region proximate the skin opening;
securing the catheter with the retainer body so that the catheter is anchored relative to the skin opening;
pivoting the first and second anchors about a longitudinal hinge region defined by the retainer body while first and second body portions of the retainer body on opposing sides of the longitudinal fold line remain physically coupled to one another so that the first and second anchors are adjusted from a deployed configuration to a removal configuration; and
removing the first and second anchors from the subcutaneous region and the skin opening.

Abstract
Some embodiments of a medical device anchor system include an anchor device that receives a catheter (or other medical instrument) and secures the catheter in place relative to a skin penetration point. In some embodiments, the anchor device can secure the catheter in an operative position relative to the skin without the use of sutures or skin tapes. In particular embodiments, the anchor device can be adjusted to a folded condition so that subcutaneous anchors are partially rotated prior to removal from the skin penetration point.
