1. A method of securing a medical instrument, comprising:
- securing an anchor device relative to a penetration point, the anchor device comprising a retainer body comprising a first body portion that is pivotably coupled to a second body portion about a longitudinal fold axis, the first body portion and the second body portion including first and second tabs, respectively, and first and second anchors that extend distally from a distal end of the retainer body, each anchor comprising a flexible tine, wherein securing the retainer body comprises;
deploying the first and second anchors in a subcutaneous region of the penetration point while in a folded configuration, wherein in the folded configuration the first anchor and the second anchor extend generally in a same direction; and
pivoting the first body portion relative to the second body portion, wherein pivoting the first body portion relative to the second body portion adjusts the first anchor and the second anchor from the folded configuration to a non-folded configuration, wherein in the non-folded configuration the first anchor and the second anchor extend outwardly away from one another, and the first and second tabs define a cutout region therebetween in the non-folded configuration to provide visualization and access of a surface under the retainer body.

16. A method of securing a medical instrument, comprising:
-
advancing an anchor device at least partially through a skin penetration point, the anchor device comprising a retainer body comprising a first body portion that is pivotably coupled to a second body portion about a longitudinal fold axis, and first and second anchors that extend distally from a distal end of the retainer body, each anchor comprising a flexible tine, the first anchor being coupled to the first body portion and the second anchor being coupled to the second body portion; deploying the first and second anchors in a subcutaneous region of the penetration point while in a folded configuration, wherein in the folded configuration the first anchor and the second anchor extend generally in a same direction; and pivoting the first body portion relative to the second body portion, wherein pivoting the first body portion relative to the second body portion adjusts the first anchor and the second anchor from the folded configuration to a non-folded configuration in which the flexible tines extend outwardly away from one another, wherein the first body portion and the second body portions define a cutout region therebetween at a proximal end opposite from the first and second anchors to provide visualization and access to a surface under the retainer body when in the non-folded configuration. - View Dependent Claims (17, 18, 19, 20)
