Abstract
The present invention is directed to an inflated interspinous spacer. The interspinous spacer is inserted into the interspinous space between adjacent spinous process in a deflated or unexpanded state, and is inflated or expanded with an injectable filler material. Upon inflation, the spacer preferably distracts the spinous processes and assumes a shape that retains the spacer in position and preferably mechanically locks with the spinous processes. The spacer includes two separate balloons configured to have different compressive modulus so that one balloon is softer and more deformable than the other balloon.
