Abstract
Some embodiments of a medical device anchor system include an anchor device that receives a catheter (or other medical instrument) and secures the catheter in place relative to a skin penetration point. In some embodiments, the anchor device can secure the catheter in an operative position relative to the skin penetration point without the use of sutures or skin tapes.
Claims19
An anchor system for securing a position of a medical instrument, comprising:
- the 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 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 retainer body comprising a detachable cap member that is entirely detachable from a lower member of the retainer body and that is removably attachable to the lower member of the retainer body via a releasable mounting relationship between engagement structures of the detachable cap member configured to mate with corresponding engagement structures of the lower member of the retainer body to releasably engage with an exterior of the external portion of the medical instrument;
- and
- the first and second anchors comprising 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.
