    Abstract: A driver assembly for affixing a surgical fastener to a target location is provided. Operation of the driver assembly inserts the surgical fastener in two stages, first an alignment stage through application of a distally directed force to partially insert the surgical fastener, and then a fastening stage to fully insert and seat the surgical fastener to a proper depth or compression level. The driver assembly comprises a spring loaded automatic trigger mechanism that may be adapted for use with a linearly insertable or a rotationally insertable surgical fastener. Application of the distally directed force actuates the trigger mechanism, wherein a corresponding impact force is delivered for seating the surgical fastener, coupled to a distal end of the driver assembly, upon alignment of cam and receiver elements embodied within the trigger mechanism.

    Abstract: A biocompatible surgical fastener, comprising a sleeve and a screw or a pin, which expands when it is implanted in a patient. The sleeve is first implanted in a pre-drilled hole in the operating area of a patient, usually in a bone, cartilage or a bone and cartilage. When a screw or a pin is installed in the sleeve, the sleeve is caused to expand thereby stabilizing the fastener in the operating area. In many embodiments the screw or pin can be removed and reinserted without disturbing the tissue in the operating area. The surgical fastener can be used to repair tissue or to secure other implant devices in a patient.

    Abstract: Strip fasteners and cranial plugs for use in reattaching a skull flap removed during brain surgery and methods of using the same. The strip fasteners are flexible and can be shaped to follow the perimeter contour of the skull flap. The cranial plugs can be used to reattach the skull flap or they can be installed after the skull flap is reattached using the strip fasteners. In some embodiments, the cranial plug(s) and strip fasteners can be installed at the same time. The strip fasteners and cranial plugs are designed to encourage bone growth and healing of the skull flap and they can be used to deliver medication and bone growth enhancement compositions to the surgical site.
