Abstract:
1. An intervertebral implant comprising: a central axis; a top part comprising a top apposed surface intersecting the central axis, a bottom inside surface, and at least one upper channel extending from the top apposed surface to the bottom inside surface; a bottom part comprising a bottom apposed surface intersecting the central axis, a top inside surface, and at least one lower channel extending from the bottom apposed surface to the top inside surface; a top joint part located between the top and bottom parts, the top joint part defining a first end surface, in contact with the bottom inside surface of the top part, a first curved articulating surface opposite the first end surface, and at least one upper joint channel extending from the first end surface to the first curved articulating surface and in communication with at least one upper channel to convey fluid to the first curved articulating surface; a bottom joint part located between the top and bottom parts, the bottom joint part defining a second end surface, in contact with the top inside surface of the bottom part, a second curved articulating surface opposite the second end surface, the second curved articulating surface contacting the first curved articulating surface of the top joint part, and at least one lower joint channel extending from the second end surface to the second curved articulating surface and in communication with at least one lower channel to convey fluid to the second curved articulating surface.
