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.

Biomedical implant inserters and related apparatus, systems, and methods

Spinal implants for positioning between adjacent vertebrae. Some embodiments may comprise a pair of opposed sidewall surfaces, a pair of opposed frictional surfaces, a first end wall joining the pair of opposed sidewall surfaces, and a second end wall recessed at least in part and joining the pair of opposed sidewall surfaces. A fish-tailed structure may be positioned within the second end wall when viewed from one of the opposed frictional surface. The fish-tailed structure may be formed so as to extend at least substantially uninterrupted between at least one of the opposed sidewall surfaces and the opposed frictional surfaces. A retention structure, such as a hole, may be positioned within the fish-tailed structure. The hole may be configured to engage a surgical implantation device.

Intervertebral implant devices

An intervertebral implant device is presented that may comprise a pair of substantially parallel opposed arcuate surfaces, a pair of substantially parallel opposed frictional surfaces each including a plurality of raised structures, a substantially curved end wall joining the par of parallel opposed arcuate surfaces, and a substantially recessed end wall joining the pair of parallel opposed arcuate surfaces. In certain embodiments, the intervertebral implant device defines one or more voids in which a bone graft material is selectively disposed. Preferably, the substantially recessed end wall is configured to selectively and pivotable receive one or more surgical implantation devices.
