Systems and methods for posterior dynamic stabilization of the spine
First Claim
1. An interspinous device for stabilizing at least one spinal motion segment comprising a first vertebra having a first spinous process and a second vertebra having a second spinous process, the device comprising:
- a tubular member having a length and a diameter and being deployable from a first configuration to a second configuration, wherein one of the length and the diameter of the tubular member in the first configuration is changed when the tubular member is in the second configuration.

Abstract
Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer or member having an unexpanded configuration and an expanded configuration, wherein the expandable member in an expanded configuration has a size, volume and/or shape configured for positioning between the spinous processes of adjacent vertebrae in order to distract the vertebrae relative to each other. The systems include one or more expandable members and a mechanical actuation means for expanding the expandable member. The methods involve the implantation of one or more devices or expandable spacers.
