Abstract:
1. An inserter for inserting and expanding a distractible intervertebral body fusion device into an intervertebral disc space defined between adjacent vertebrae of a patient, comprising: a shaft frame having a proximal end and a distal end; a drive shaft assembly extending from the distal end of the shaft frame, the drive shaft assembly adapted to be attached to a distractible intervertebral body fusion device such that rotation of the drive shaft assembly causes the device to expand between a compressed configuration and an expanded configuration; a support shaft assembly extending from the distal end of the shaft frame adjacent the drive shaft assembly, the support shaft assembly adapted to be attached to the distractible intervertebral body fusion device to stabilize the device as the drive shaft assembly is rotated to expand the device; and a drive housing operably connected to the shaft frame and extending outwardly from the shaft frame and non-coaxially with the drive shaft assembly, the drive housing extending from the shaft frame at a location between the distal end and the proximal end of the shaft frame, the drive housing providing access into the shaft frame to a proximal end of the drive shaft assembly.
