Systems and methods for posterior dynamic stabilization of the spine
First Claim
1. A 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, wherein an interspinous space is defined therebetween, the device comprising:
- a body sized and shaped for positioning within the interspinous space; and
at least one extension member movably attached to the body, wherein the at least one extension member can be moved from an undeployed position to a deployed position wherein the device has a first profile when the at least one extension member is in the undeployed position and a second profile when the at least one extension member is in the deployed position, wherein the second profile is greater than the first profile.

Abstract
Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer having an undeployed configuration and a deployed configuration, wherein the spacer has axial and radial dimensions for positioning between the spinous processes of adjacent vertebrae. The systems include one or more spacers and a mechanical actuation means for delivering and deploying the spacer. The methods involve the implantation of one or more spacers within the interspinous space.

105. A method for treating at least one spinal motion segment comprising a first vertebra having a first spinous process and a second vertebra having a second spinous process and an interspinous space defined between the first and second spinous processes, the method comprising:
-
introducing a device within the interspinous space;
adjusting at least one of the shape and size of the device;
using the device to statically stabilize the first and second spinous processes relative to each other; and
subsequently using the device to dynamically stabilize the first and second spinous processes relative to each other. - View Dependent Claims (106, 107, 108)
