1. A method of anchoring a medical instrument, comprising:
- advancing the medical instrument through a skin penetration point of a patient'"'"'s body, the medical instrument comprising an external portion configured to reside external to the skin penetration point when the medical instrument is inserted into the skin penetration point;
engaging the external portion of the medical instrument with a retainer device by adjusting a flexible portion of the retainer device from a first configuration to a second configuration, the retainer device comprising;
a retainer body comprising the flexible portion;
a first anchor comprising a first external shaft portion, the first anchor extending distally from a distal end of the retainer body and toward the skin penetration point when the medical instrument is inserted into the skin penetration point and engaged with the retainer body; and
a second anchor comprising a second external shaft portion, the second anchor extending distally from the distal end of the retainer body and toward the skin penetration point when the medical instrument is inserted into the skin penetration point and engaged with the retainer body, the first and second external shaft portions positionable side-by-side during insertion and movable relative to one another during removal from a subcutaneous region; and
inserting the first and second anchors through the skin penetration point so that at least a portion of each of the first and second anchors is deployed in the subcutaneous region proximate the skin penetration point, wherein the first external shaft portion of the first anchor and the second external shaft portion of the second anchor are positioned side-by-side during insertion through the skin penetration point.
