Abstract:
1. An implant adapted to be implanted in the spine of a patient comprising: a shield surrounding a shield cavity; a deflection rod having a proximal end and a distal end; the deflection rod being disposed in the shield cavity such that the proximal end extends out of the shield cavity and the distal end is connected to said shield; wherein a proximal portion of the deflection rod is spaced from the shield within the shield cavity such that the proximal portion of the deflection rod can deflect within said shield cavity thereby permitting the proximal end of the deflection rod to deflect in response to a load applied to the proximal end of the deflection rod; and wherein deflection of the proximal end of the deflection rod has a non-linear relationship with the load applied to the proximal end of the deflection rod.
