Abstract:
1. A spinal implant assembly for filling an interspinous process space to act as a spacer between bone comprising: a) a body portion dimensioned and configured for percutaneous introduction into the interspinous process space to act as a spacer between the bone, the body portion having an exterior surface defining opposing depressions to match a profile of the bone and defining an enclosed interior cavity; and b) a plurality of curved locking wings each adapted and configured to move along a respective curved path between a stowed position retracted within the enclosed interior cavity of the body portion and a deployed position extended outward from the enclosed interior cavity of the body portion through respective openings formed in the body portion, wherein a pawl is located on the exterior surface of the body portion adjacent each opening in the body portion and each locking wing includes ratchet teeth for engaging the respective pawl to prevent the locking wings from moving back into the enclosed interior cavity of the body portion when deployed, wherein after deployment of the locking wings, the locking wings and the opposing depressions secure the body portion in an intersinous space defined by a pair of adjacent spinous process, such that each spinous process has the profile to complimentarily match the respective depression of the body portion, wherein the exterior surface of the body portion is smooth so that the spinous processes are not damaged during insertion of the body portion between the spinous process.
