Abstract
Various surgical devices and methods for facilitating distraction of adjacent vertebrae and/or insertion of an intervertebral implant material therebetween are disclosed. The devices include an elongated barrel having a cannula. A distal end of the barrel is configured to engage the adjacent vertebrae. Slots may be formed on at least a portion of the barrel such that at least the distal end of the barrel may be expanded to distract vertebrae. In one embodiment, an inner member is reciprocally positioned within the barrel. The inner member includes features that engage one or more surfaces of the barrel to expand the distal end of the barrel as the inner member moves with respect to the barrel. In some embodiments, cams are used to expand the distal end of the barrel.
