Abstract
A method and apparatus can include: a delivery tool having an insertion mandrel; an implant having a distal segment coupled to a proximal segment, the proximal segment having a proximal segment upper and a proximal segment lower, the distal segment having a distal segment upper and a distal segment lower, the implant including: a straight configuration based on the insertion mandrel being extended through the proximal segment and the distal segment, and a curved configuration based on the insertion mandrel being retracted from the distal segment; and an expansion mandrel configured for insertion into the implant, the implant including an expanded configuration based on the expansion mandrel being inserted between the proximal segment upper and the proximal segment lower, and being inserted between the distal segment upper and the distal segment lower.
