ABSTRACT:
An implantable spinous process stabilization assembly includes a body, a bent arm and a straight arm. The body includes first and second crosspieces arranged parallel to each other, a first plate extending in a direction at right angle to first ends of the first and second crosspieces, first and second rings extending from second ends of the first and second crosspieces, respectively and a second plate extending from a base of the first and second rings, at right angle to the first and second crosspieces and in an opposite direction to the first plate's direction. The bent arm and the straight arm are configured to pivot around an axis perpendicular to the first and second rings and to set first and second pivot angles with the first and second plates, respectively, thereby defining first and second spaces configured to receive and lock onto first and second spinous processes, respectively.
