Instrumentation for inserting and deploying an expandable interbody spinal fusion implant
First Claim
1. An apparatus for inserting an expandable spinal implant having an expander adapted to increase the height of the implant, said apparatus comprising:
- an implant holder having a longitudinal axis, a passage along the longitudinal axis, and a distal end with an implant engagement area adapted to cooperatively engage the implant; and
an expander driver adapted to engage the expandable implant, said expander driver having a shaft adapted to pass through said passage of said implant holder, said shaft of said expander driver having a distal end adapted to engage the expander of the expandable implant, wherein the expander driver is adapted to rotate while engaging the expander without the expander driver advancing distally relative to the implant holder.

Abstract
Instruments for inserting and expanding interbody spinal implants having an expandable height are disclosed. The Instruments are provided for engaging expanders of the implants to increase the heights thereof. The instruments include an implant holder and an expander driver. The implant holder has a longitudinal axis, a passage along the longitudinal axis, and a distal end with an implant engagement area adapted to cooperatively engage the implant. The expander driver has a shaft adapted to pass through the passage of the implant holder, and a distal end adapted to engage the expander of the expandable implant.
