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 use of sutures or skin tapes.
Claims20
A method of anchoring a medical instrument to a skin penetration point, comprising:
- inserting first and second anchors of an anchor device through the skin penetration point so that first and second flexible tines of the first and second anchors, respectively, are deployed in a subcutaneous region proximate the skin penetration point, said anchor device including:
- a retainer body releasably engageable with an exterior of the medical instrument, the retainer body comprising a flexible portion adjustable from a first configuration to a second configuration;
- the first anchor comprising a first shaft portion that extends distally from a distal end of the retainer body, toward the skin penetration point, and to the first flexible tine in the subcutaneous region;
- and
- the second anchor comprising a second shaft portion that extends distally from the distal end of the retainer body, toward the skin penetration point, and to the second flexible tine in the subcutaneous region, wherein the first and second shaft portions are positioned side-by-side during said inserting the first and second anchors of the anchor device through the skin penetration point;
- and
- removing the first and second flexible tines from the subcutaneous region, wherein the first and second shaft portions are movable relative to one another during removal from the subcutaneous region.

A method of anchoring a medical instrument to a skin penetration point, comprising:
- releasably securing a retainer body of an anchor device to an exterior of the medical instrument while the medical instrument resides in the skin penetration point and while first and second flexible tines of the anchor device are deployed in a subcutaneous region proximate the skin penetration point, said anchor device including:
- the retainer body that releasably secures to the medical instrument, the retainer body comprising a flexible portion adjustable from a first configuration in which the medical instrument is movable independent from the retainer body to a second configuration in which the retainer body is configured to engage with the exterior of the medical instrument;
- a first anchor comprising a first shaft portion that extends distally from a distal end of the retainer body, toward the skin penetration point, and to the first flexible tine deployed in the subcutaneous region;
- and
- a second anchor comprising a second shaft portion that extends distally from the distal end of the retainer body, toward the skin penetration point, and to the second flexible tine deployed in the subcutaneous region;
- disengaging the retainer body of the anchor device from the medical instrument;
- and
- removing the first and second flexible tines from the subcutaneous region, wherein the first and second shaft portions are movable relative to one another during removal from the subcutaneous region.
