Systems and methods for anchoring medical devices

An anchor device for securing the position of a medical instrument, the anchor device comprising:

• a retainer body comprising a first body portion and a second body portion;
• one or more flexible adhesive strips mounted to the retainer body and being configured to adhesively attach with one or more corresponding exterior surfaces of the medical instrument;
• and
• first and second anchors that extend distally from a distal end of the retainer body, each anchor comprising a flexible tine that is deployable in a subcutaneous region to secure the retainer body relative to a penetration point, the first anchor being coupled to the first body portion and the second anchor being coupled to the second body portion;
• wherein the first body portion of the retainer body is movable relative to the second body portion about a longitudinal fold axis while the first and second body portions are coupled so that the first and second anchors are adjustable from a first configuration in which the flexible tines extend outwardly away from one another to a second configuration in which the flexible tines extend generally in the same direction;
• and
• wherein the one more flexible adhesive strips comprise a first adhesive strip configured to define an adhesive strip fold axis, the first adhesive strip foldable upon itself about the adhesive strip fold axis and around an exterior surface of the medical instrument.

A system for securing the position of a medical instrument, the system comprising:

• a medical instrument comprising a distal portion configured to extend through a skin penetration point and into a body, and an external portion configured to reside outside the body when the distal portion extends through the skin penetration point;
• and
• an anchor device comprising;
• a retainer body comprising a first body portion that is coupled to a second body portion;
• one or more flexible adhesive strips mounted to the retainer body and being configured to adhesively attach with one or more surfaces of the external portion of the medical instrument;
• and
• first and second anchors that extend distally from a distal end of the retainer body, each anchor comprising a flexible tine that is deployable through the skin penetration point occupied by the medical instrument and into a subcutaneous region to secure the retainer body relative to the skin penetration point, the first anchor being coupled to the first body portion and the second anchor being coupled to the second body portion;
• wherein the first body portion of the retainer body is pivotable relative to the second body portion about a longitudinal fold axis while the first and second body portions are pivotably coupled so that the first and second anchors are adjustable from one another from a first configuration to a second configuration in which the flexible tines extend generally in the same direction;
• and
• wherein the one more flexible adhesive strips comprise a first adhesive strip configured to define an adhesive strip fold axis, the first adhesive strip foldable upon itself about the adhesive strip fold axis and around an exterior surface of the medical instrument.
