摘要：
An expandable interspinous process spacer is disclosed that includes at least two chambers, one disposed within the other. Each of the at least two chambers can receive an injectable biocompatible material, which advantageously may have different material properties such as hardness. Further, the expandable interspinous process spacer can be changed from a deflated configuration to an inflated configuration. In the inflated configuration, the expandable interspinous process spacer can engage and support a superior spinous process and an inferior spinous process.
