1. A method of using a medical anchor system, comprising:
- advancing a medical device through a skin opening;
advancing an anchor device having first anchor including a first subcutaneous tine and a second anchor including a second subcutaneous tine toward a skin opening while the anchor device is in a deployment configuration, each of the subcutaneous tines having a curved shape which terminates at a tip of a free end;
inserting the subcutaneous tines through the skin opening and into a subcutaneous region adjacent to an underside of a skin layer while the subcutaneous tines are in the deployment configuration;
securing the medical device with a retainer body of the anchor device so that the medical device is anchored relative to the skin opening, the retainer body comprising first and second body portions, the first anchor fixedly coupled to the first body portion and the second anchor fixedly coupled to the second body portion;
adjusting the first and second anchors to a removal configuration different from the deployment configuration by adjusting the first body portion relative to the second body portion;
removing the first and second anchors from the subcutaneous region and the skin opening;
wherein the first and second body portions remain physically coupled to one another when adjusted from the deployment configuration to the removal configuration.

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.

14. A method of using a medical anchor system, comprising:
-
advancing a medical device through a skin opening; advancing an anchor device having first anchor including a first subcutaneous tine and a second anchor including a second subcutaneous tine toward a skin opening while the anchor device is in a deployment configuration, each of the subcutaneous tines having a curved shape which terminates at a tip of a free end; inserting the subcutaneous tines through the skin opening and into a subcutaneous region adjacent to an underside of a skin layer while the subcutaneous tines are in the deployment configuration, wherein the tips of the free ends of the tines are not the first portion of the tines inserted through the skin opening; securing the medical device with a retainer body of the anchor device so that the medical device is anchored relative to the skin opening, the retainer body comprising first and second body portions, the first anchor rigidly fixed to the first body portion and the second anchor rigidly fixed to the second body portion; adjusting the first and second anchors to a removal configuration different from the deployment configuration by adjusting the first body portion relative to the second body portion, the first and second body portions remaining physically coupled to one another when adjusted from the deployment configuration to the removal configuration; removing the first and second anchors from the subcutaneous region and the skin opening. - View Dependent Claims (15, 16, 17, 18)
