1. A spinal implant apparatus, comprising:
- a proximal portion configured to be deformed from a first configuration to a second configuration to cause deformation of the proximal portion;
a distal portion configured to be deformed from a first configuration to a second configuration to cause deformation of the distal portion;
a non-expanding central portion disposed between the proximal portion and the distal portion, the non-expanding central portion configured to engage adjacent spinous processes;
wherein the distal portion comprises a distal section disposed distally from the central portion and a deformable intermediate section disposed between the distal section and the central portion;
wherein the distal portion, the central portion, and the proximal portion are disposed sequentially along a longitudinal axis such that the longitudinal axis extends therethrough when the distal portion and the proximal portion are in their first configurations;
wherein the distal section is disposed along the longitudinal axis such that the longitudinal axis extends therethrough when the distal portion is in both its first and second configurations.

Abstract
An apparatus includes an elongate member having a proximal portion configured to be deformed from a first configuration to a second configuration. The elongate member has a distal portion configured to be deformed from a first configuration to a second configuration. A non-expanding central portion is positioned between the proximal portion and the distal portion. The non-expanding central portion is configured to engage adjacent spinous processes.
