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, the device comprising:

  • a helical body including a first spinous process-receiving recess, a second spinous process-receiving recess, and at least two segments, the at least two segments physically contact each other such that a force provided by a delivery device detachably coupled to the device causes one or both of the segments to move in a direction with a component substantially perpendicular to a longitudinal axis of the device, the helical body having a cross-sectional shape that varies along at least a portion of the longitudinal axis, the helical body having an undeployed configuration with an axial dimension and a radial dimension substantially transverse to the axial dimension, and a deployed configuration having an axial dimension and a radial dimension substantially transverse to the axial dimension such that the first and second spinous process-receiving recesses move away from one another when the helical body moves from the undeployed configuration to the deployed configuration, and wherein the radial dimension of at least a portion of the helical body in the undeployed configuration is less than the radial dimension of at least a portion of the helical body in the deployed configuration.
