Patent number: 9668882Abstract: 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.Type: GrantFiled: February 7, 2014Date of Patent: June 6, 2017Assignee: Amedica CorporationInventors: Prabhakar Thirugnanasambandam, John Cobb, William Atkinson, Peter Harris, Chad Wayne Lewis
