Abstract

See full text

An expandable intervertebral implant includes a first endplate and a endplate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second plates together. The first and second wedge members configured to move between a first collapsed position and a second expansion position. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The first and second wedge members can be coupled to the upper and lower endplates at guide members that are asymmetric. An instrument can be coupled to the implant so as to provide a force to the actuation member that causes the wedge members to move between the collapsed position and the expansion position. The instrument can include a drive shaft and a toggle member that is configured to move the drive shaft between a first position whereby the drive shaft is configured to drive an attachment pin into the implant, and a second position whereby the drive shaft is aligned to drive the actuation member to rotate.
