  • Publication number: 20230047910
    Abstract: This disclosure includes soft-tissue fasteners for coupling an implant to soft tissue, bone fasteners for coupling an implant to bone, fastener-delivery apparatuses (e.g., tools) for delivering such soft-tissue fasteners and bone fasteners, fastener cartridges for use with certain of the fastener-delivery apparatuses. The present fasteners generally include at least one barbed shaft and an enlarged head spaced from a distal end of the shaft. Some of the present fasteners include two barbed shafts and an enlarged head spanning the two shafts. This disclosure also includes kits that comprise a plurality of fasteners (e.g., a plurality of soft-tissue fasteners, a plurality of bone fasteners, or both).
