Some embodiments of an anchor device may include bendable anchor mechanism that is deployable in a subcutaneous layer to releasably secure the anchor device to a patients body. Certain embodiments of the anchor mechanism may include one or more barbs that flexibly bend in response to an insertion or removal force. As such, the anchor mechanism may be inserted into a subcutaneous layer, and removed from the subcutaneous layer, without the need for a separate actuation device to extend or retract the barbs.
