Claims20
A method for securing a medical device relative to a skin opening that is occupied by the medical device, the method comprising:
- inserting a distal portion of a medical device through an opening in a skin layer and into a targeted body site;
- advancing first and second flexible anchors of an anchor device contemporaneously through the same opening in the skin layer and into a subcutaneous region under the skin layer while the flexible anchors are in a first position, wherein the anchor device further comprises:
- a medical device retainer body including a longitudinal channel configured to releasably engage with an outer surface of an external portion of the medical device;
- and
- an anchor assembly contacting the retainer body and spaced apart from the channel of the retainer body;
- and
- moving the first and second flexible anchors from the first position to a subcutaneously deployed position in which a first free end of the first anchor and a second free end of the second anchor extend outwardly from one another in generally opposite directions and are configured to engage tissue along an underside of the skin.
