Patent ID: 7763073

Claim:
An interspinous implant for insertion into an interspinous space between a first and second spinous process, the implant comprising: a) a central body having: i. an upper surface for bearing against an upper spinous process, ii. a lower surface for bearing against a lower spinous process, iii. first and second side surfaces defining a transverse axis, and iv. a first opening extending from the first side surface into the body, b) a first extension having an upper end having an upper surface, a lower end having a lower surface, an inner surface having a convex contour and an outermost surface having a concave contour, and a first transverse throughhole, the first extension being separate from the central body, c) a second extension having an upper end having an upper surface, a lower end having a lower surface, an inner surface having a convex contour and an outermost surface having a concave contour, and a second transverse throughhole, the second extension being separate from the central body, d) a rivet comprising: i. a first connecting pin fitting in the first transverse throughole and having a male end, and ii. a second connecting pin fitting in the second transverse throughole and having a female end, e) means for connecting the first side surface of the central body to the inner surface of the first extension, wherein the first side surface of the central body contacts the inner surface of the first extension, wherein the second side surface of the central body contacts the inner surface of the second extension, wherein the upper ends of the extensions collectively define an upper bracket, and wherein the lower ends of the extensions collectively define a lower bracket, wherein the means for connecting comprises the first opening and a second opening respectively extending into the central body from the first and second side surfaces.
