Abstract
A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. The implant provides a spinal extension stop while allowing freedom of spinal flexion.
Claims25
A method, comprising:
- inserting at least a portion of an implant having a first member and a second member between adjacent spinous processes in a first configuration;
- subsequently, moving the second member of the implant relative to the first member of the implant into a second configuration such that tips of the first and second members are disposed farther away from each other in the second configuration than in the first configuration;
- wherein, in the second configuration, the implant extends transversely through a sagittal plane defined by the adjacent spinous processes at a location directly between the spinous processes;
- wherein said moving comprises moving the tip of the second member from a position not adjacent a lateral side of one of the spinous processes to a position adjacent the lateral side of the one of the spinous processes.

A method, comprising:
- inserting percutaneously an implant having at least a first portion and a second portion such that the first portion and the second portion are inserted simultaneously;
- disposing percutaneously at least a portion of the first portion of the implant between adjacent spinous processes such that the first portion extends transversely through a sagittal plane defined by the adjacent spinous processes;
- while the first portion extends transversely through the sagittal plane directly between the adjacent spinous processes, applying a force to the second portion of the implant such that the second portion moves relative to the first portion;
- wherein when applying the force, the first portion and a tip of the second portion move away from each other and the tip of the second portion moves from a position not adjacent a lateral side of one of the spinous processes to a position adjacent the lateral side of the one of the spinous processes.
