Abstract:
1. An inserter for expanding an expandable spinal interbody fusion device and inserting a plurality of inserts therewithin, comprising: an elongate track having a distal end and a proximal end, said distal end being configured to be releasably attached to said device, said inserter including at said proximal end an actuator, said track linearly supporting said plurality of inserts for sequential individual insertion into said device, an elongate lifting platform which moves on said track and operably coupled to said actuator for translational movement in axially opposite projecting and is retracting directions, said lifting platform including a lifting surface for engaging a cooperatively configured receiving surface of said device when said lifting platform is in said projecting direction to expand said device, said inserter including an elongate driver which moves on said track and is operably coupled to said actuator for translational movement at least partially independently of said lifting platform in axially opposite directions for contacting and driving an insert from said plurality of inserts into said device, wherein said movement of said lifting platform in said projecting direction is effected in a first stroke of said actuator, and said movement of said lifting platform in said retracting direction is effected in a second stroke of said actuator.
