  • Patent number: 10709874
    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 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.

  • Publication number: 20200214627
    Abstract: A device includes a handle, an expandable structure including a plurality of splines extending from a proximal hub to a distal hub, a first electrode on a first spline of the plurality of splines, an outer tube extending from the handle to the proximal hub, and a shaft extending through the outer tube from the handle to the distal hub. The expandable structure has a collapsed state and a self-expanded state. The handle is configured to retract the shaft. Retracting the shaft may expand the expandable structure outward of the self-expanded state.

  • Publication number: 20190275300
    Abstract: Some embodiments of a medical anchor device include an elongate body coupled with deployable subcutaneous anchors to secure a catheter instrument (or other medical instrument) in place relative to a skin penetration point. In some circumstances, the elongate body may be in the form of catheter hub body, and the subcutaneous anchors can be deployed from the hub body by adjustment of a movable actuator. A locking member can interact with the actuator so as to retain the actuator in the deployed orientation during the medical procedure.

  • Publication number: 20190134354
    Abstract: Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors. In some implementations, the anchor device can be installed using a technique in which the subcutaneous anchors undergo relatively little or no flexing when being inserted through the skin into the subcutaneous region between the skin and underlying muscle tissue which may be occupied by fatty tissue.
