Patent ID: 7655043

Claim:
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 ends and first and second axial walls extending along a length of said implant body and spaced apart along a transverse axis extending along a height of said implant body, at least one of said axial walls including first and second axial wall portions laterally offset from one another along a width of said implant body, said first axial wall portion positioned laterally adjacent said second axial wall portion, said first and second axial wall portions extending continuously and substantially entirely along said length of said implant body from said first end to said second end and being flexibly deformable to facilitate flexible deformation of said first axial wall portion; and an expansion member co-acting with said first axial wall portion to flexibly deform said first axial wall portion and outwardly displace a central region of said first axial wall portion relative to said second axial wall portion generally along said transverse axis to transition said implant body from said initial configuration to said expanded configuration, said expansion member engaged with said central region of said first axial wall portion in said expanded configuration; and wherein said implant body includes first and second transverse end walls interconnecting opposite end portions of said first axial wall with opposite end portions of said second axial wall, and wherein said first and second axial wall portions each extend continuously from said first transverse end wall to said second transverse end wall.
