Abstract:
1. A device for immobilizing adjacent spinous processes, the device comprising: a first element comprising a first element side configured to grip first process sides of the adjacent spinous processes and comprising a first separation bar projecting to the first element side in a first direction such that the first separation bar extends between the adjacent spinous processes when the first element side engages the adjacent spinous processes; a spacer element comprising an adjustment bar and a second separation bar fixedly coupled to and projecting from the adjustment bar such that the adjustment bar and the second separation bar are not collinear; and a second element comprising (a) a second element side configured to grip second process sides of the adjacent spinous processes, (b) a receptacle configured to receive the first separation bar in the first direction, (c) a hole configured to receive the adjustment bar in a second direction, the second direction being transverse to the first direction, and (d) a clamping feature configured to selectably lock the first separation bar and the adjustment bar relative to each other and to the second element, the clamping feature having a locked configuration and an unlocked configuration; and wherein when the first element, the second element, and the spacer element are assembled with the clamping feature in the unlocked configuration, the spacer element is translatable in the second direction relative to the second element; and wherein the second separation bar extends between the adjacent spinous processes when the adjustment bar is in the hole and the second element side engages the adjacent spinous processes.
