Expandable spinal implant and associated instrumentation
First Claim
1. An expandable spinal implant, comprising:
- an implant body having a longitudinal axis and being transitionable between an initial configuration and an expanded configuration, said implant body including first and second axial walls spaced apart along a transverse axis, at least one of said axial walls including first and second axial wall portions laterally offset from one another; and
an expansion member co-acting with said first wall portion to outwardly displace said first wall portion relative to said second wall portion generally along said transverse axis to transition said implant body from said initial configuration to said expanded configuration.

Abstract
An expandable spinal implant including an implant body transitionable between an initial configuration and an expanded configuration. The implant body includes first and second axial walls spaced apart along a transverse axis, with at least one of the walls including first and second axial wall portions laterally offset from one another. An expansion member co-acts with the first wall portion to outwardly displace the first wall portion relative to the second wall portion to transition the implant body to the expanded configuration. In another embodiment, the first wall portion defines a recessed region relative to the second wall portion when the implant body is in the initial configuration, and wherein the recessed region is outwardly expanded as the implant body is transitioned to the expanded configuration. In a further embodiment, the first wall portion is movable while the second wall portion remains substantially stationary.
