Patent ID: 7837711

Claim:
A device to provide an inferior support for an interspinous implant between an L5 vertebrae and a spinous process of a sacrum, the device comprising: first and second anchors each with a tapered distal tip configured to be mounted to the sacrum; first and second lateral extensions with apertures to receive the anchors to secure the device to the sacrum; a first face that extends outward in a posterior direction from the first lateral extension when the first lateral extension is mounted to the sacrum; a second face that extends outward in the posterior direction from the second lateral extension when the second lateral extension is mounted to the sacrum; a bearing face extending between the lateral extensions and connected to each of the first and second faces; a lip positioned at an anterior end of the bearing face and including a different width than the bearing face; a recess formed and enclosed on a superior side by the bearing face and on the lateral sides by the first and second faces, the recess including an open side that is oriented in an anterior direction when the device is mounted to the sacrum and is configured to receive the spinous process of the sacrum, the recess including a tapered width measured between the first and second faces that increases from the superior side to an open inferior side; the bearing face having a height in an anterior-posterior direction greater than the spinous process of the sacrum and oriented in a superior direction when the device is mounted to the sacrum to support the interspinous implant.
