System for anchoring medical devices

摘要

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 without the use of sutures or skin tapes. In particular embodiments, the anchor device can be adjusted to a folded condition so that subcutaneous anchors are partially rotated prior to removal from the skin penetration point.

主权项

1. An anchor device for securing the position of a catheter, comprising:
an external retainer assembly to releasably couple to a catheter, the external retainer assembly having a longitudinal axis extending from a proximal end to a distal end; and first and second anchors that are fixedly mounted to the external retainer assembly and that extend distally from the distal end of the external retainer assembly, each anchor comprising a flexible tine that is deployable in a subcutaneous region to secure the external retainer assembly relative to a skin penetration point, wherein the external retainer assembly defines a gripping channel extending generally parallel to the longitudinal axis of the external retainer assembly so as to engage an exterior surface of to the catheter when the external retainer assembly releasably couples to the catheter, the gripping channel having a non-circular cross-sectional shape in a plane generally perpendicular to the longitudinal axis.
