Abstract
An insertion device is configured to access a disc positioned between adjacent vertebrae. The insertion device includes a cannula having a passage formed therein. The cannula has an exit aperture. An obturator is substantially positioned within the passage formed in the cannula. One end of the obturator has a probe and the other end of the obturator has a head. An impaction cap is in contact with the cannula and is positioned to cover the head of the obturator. The impaction cap is configured to allow at least a portion of the cannula to be inserted through a portion of one vertebra without deployment of the probe of the obturator through the exit aperture of the cannula.
