  • Patent number: 9668882
    Abstract: Embodiments of apparatus, systems, and methods relating to spinal implants. In some embodiments, the spinal implant may comprise a first sidewall, a second sidewall opposite from the first sidewall, a pair of opposed frictional surfaces each comprising a plurality of raised structures, a first end wall joining the pair of opposed sidewall surfaces, and a second end wall joining the first sidewall and the second sidewall. The second end wall may comprise a recess formed by a first wall portion and a second wall portion arranged at an angle to one another to form a fish-tailed structure configured to be engaged with an inserter instrument. The interface between the recess and the inserter instrument may be configured to at least substantially eliminate any point or line contacts between the inserter instrument and the spinal implant during a flip maneuver of the spinal implant within an intervertebral space of a patient.

    Abstract: Apparatus, methods, and systems relating to spinal implants and instruments for installing such implants. In some embodiments, a spinal implant may comprise an opening configured to receive an installation rod for installing the spinal implant within an intervertebral space of a patient. The opening may be positioned within a wall of the spinal implant, and may comprise a peripheral edge defined by the wall of the spinal implant. An installation rod may be provided that may be configured to be positioned within the opening of the spinal implant, and may comprise an engagement section configured to engage a portion of the spinal implant defining the opening at a location spaced apart from the peripheral edge such that the highest forces applied to the spinal implant in coupling the spinal implant with the installation rod during installation are not applied to the portion of the opening defined by the peripheral edge.
