Abstract:
1. An anchor system for securing a medical instrument, comprising: a retainer body to releasably couple with a catheter configured for insertion through a skin penetration point; a plurality of flexible anchors coupled to the retainer body and being configured to extend distally from a distal end of the retainer body, each anchor comprising a flexible tine that is deployable in a subcutaneous region adjacent to a skin layer to secure the retainer body relative to the skin penetration point; and a retention member coupled to the retainer body so that the retention member directly engages an outer circumferential surface of the catheter when the retainer body couples with the catheter, wherein the retention member at least partially defines a gripping channel configured to at least partially surround the outer circumferential surface of the catheter when the retention member engages the catheter, wherein the gripping channel is at least partially defined by a wall comprising a compliant gripping material to press against the outer circumferential surface of the catheter when the retention member engages the catheter, wherein the flexible tines of the plurality of flexible anchors are positioned distal to the distal end of the retainer body for deployment in the subcutaneous region adjacent to the skin layer.
