1. An anchor system, comprising:
- a medical instrument that is insertable into a skin penetration point, 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; and
an anchor device comprising a retainer body and first and second anchors, wherein;
the retainer body comprises a cap member and a lower body member and the retainer body is configured to releasably engage with an exterior of the external portion of the medical instrument when the medical instrument is inserted into the skin penetration point, the cap member releasably engageable with the lower member via an engagement structure of the cap member configured to mate with a corresponding engagement structure of the lower member;
the retainer body comprises a flexible portion such that the retainer body is flexibly adjustable between a first configuration and a second configuration, the retainer body configured to engage with the exterior of the external portion of the medical instrument in the second configuration; and
the first and second anchors comprise first and second external shaft portions, respectively, that extend 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, the first anchor comprising a first subcutaneous tine coupled to the first external shaft portion, and the second anchor comprising a second subcutaneous tine coupled to the second external shaft portion, wherein the first and second subcutaneous tines of the first and second anchors are deployable in a subcutaneous region along an underside of skin to secure the retainer body relative to the skin penetration point;
wherein the external shaft portions of the first and second anchors are positionable side-by-side during insertion and are movable relative to one another during removal from the subcutaneous region.
