First Claim
Patent Images
1. An implant for relieving pain associated with at least one of the spinal column and surrounding tissues and structures, which implant is positionable between adjacent spinous processes of the spinal column, the implant comprising:
- a first unit including a central body, a guide and a first wing, said first wing located at a first end of said body and said guide extending from a second end of said body located distally from said first wing,a sleeve provided over said central body, said sleeve at least partially spaced from said central body in order to allow for the deflection of said sleeve toward said central body;
a second wing; and
a device that secures the second wing to the first unit.

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.
