SPINOUS PROCESS FIXATION DEVICE

摘要

An implantable spinous process stabilization assembly 10 includes a body 12, a bent arm 14 and a straight arm 16. The body 12 includes first and second crosspieces 40, 42 arranged parallel to each other, a first plate 44 extending in a direction at right angle to first ends of the first and second crosspieces 40, 42, first and second rings 48, 50 extending from second ends of the first and second crosspieces 40, 42, respectively and a second plate 46 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 14 and the straight arm 16 are configured to pivot around an axis perpendicular to the first and second rings 48, 50, 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 4a, 4b, respectively.
