Patent ID: 8591549

Claim:
A device, comprising: a front face; a rear face; an upper body portion defining an upper saddle wherein the upper body portion has a first modulus of elasticity, the upper saddle is configured to receive and support a superior spinous process; a lower body portion having a first sidewall and a second sidewall defining a lower saddle; the upper body portion separated from the lower body portion by an axial plane wherein the lower body portion has a second modulus of elasticity wherein the second modulus is greater than the first modulus, each sidewall flares out at angle between 25 degrees and 35 degrees such that contact with the inferior spinous process is avoided; the lower body portion including a left lower lobe and a right lower lobe, each lobe being adjacent to an opposite side of the lower saddle; a left sidewall, a right sidewall and a sagittal plane dividing the device into a left part and a right part, the left sidewall and the right sidewall each extending from the upper body portion to the lower body portion and extending away from the sagittal plane in a direction from the upper body portion to the lower body portion such that a first distance between the left sidewall and the right sidewall adjacent to the upper body portion is less than a second distance between the left sidewall and the right sidewall adjacent to the lower body portion; and a left channel extending through the device in the left lower lobe and a right channel extending through the device in the right lower lobe.
