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 penetration point without use of sutures or skin tapes.
Claims20
A method of using an anchor device at a skin penetration point, the method comprising:
- inserting first and second anchors of the anchor device through the skin penetration point with first and second shaft portions positioned so that first and second flexible tines of the first and second anchors, respectively, are deployed in a subcutaneous region proximate the skin penetration point, the first and second shaft portions of the first and second anchors extending from a distal end of a retainer body that is releasably engageable with an exterior of a medical instrument;
- separating the retainer body into a first body portion including the first anchor and a second body portion including the second anchor;
- and
- removing the first and second flexible tines from the subcutaneous region by moving the first and second shaft portions relative to one another.

A method of anchoring a medical instrument to a skin penetration point, the method comprising:
- releasably securing a retainer body of an anchor device to an exterior of the medical instrument while the medical instrument resides in the skin penetration point and while first and second flexible tines of the anchor device are deployed in a subcutaneous region proximate the skin penetration point;
- disengaging the medical instrument from the retainer body of the anchor device;
- after said disengaging, separating the retainer body of the anchor device into first and second body portions, the first body portion coupled to a first shaft portion extending from a distal end of the first body portion toward the skin penetration point and to the first flexible tine deployed in the subcutaneous region, and the second body portion coupled to a second shaft portion extending from a distal end of the second body portion toward the skin penetration point and to the second flexible tine deployed in the subcutaneous region;
- and
- removing the first and second flexible tines from the subcutaneous region by moving the first and second shaft portions relative to one another.
