First and second stirrup-shaped brackets extend in opposite directions from the first and second saddle-shaped portions for engaging first and second spinous processes.

主权项

1. An interspinous implant comprising:
a substantially S-shaped body having first and second ends; a first U-shaped extension attached to the first end, the first extension defining a first opening between a first pair of opposing legs and engageable to a first spinous process at the first opening; a second U-shaped extension attached to the second end, the second extension defining a second opening between a second pair of opposing legs and engageable to a second spinous process at the second opening; a first open saddle-shaped portion connected to the first U-shaped extension and having a first thickness; a second open saddle-shaped portion connected to the second U-shaped extension and having a second thickness; and an intermediate portion that is shared by the first and second saddle-shaped portions, the intermediate portion having a third thickness, the third thickness being greater than the first and second thicknesses; wherein the first and second open saddle-shaped portions are positioned on opposite sides of the intermediate portion in an opposing orientation along a body axis that crosses the first open saddle-shaped portion at the first thickness, the intermediate portion at the third thickness and the second open saddle-shaped portion at the second thickness and wherein the body axis is parallel to the first and second openings.
