Device For Securing An Implant To Tissue

A spinal implant for being secured between adjacent vertebrae, the spinal implant comprising:

• an implant body configured for being inserted between adjacent vertebral bodies in an insertion orientation and rotated between the vertebral bodies to an implanted orientation;
• outwardly facing sidewall surfaces of the implant body spaced from each other by a predetermined distance and configured to provide low-friction engagement with surfaces of the adjacent vertebral bodies with the implant body in the insertion orientation;
• a first set of aligned teeth formed on the implant body adjacent one of the sidewall surfaces for frictionally engaging the surface of one of the adjacent vertebral bodies with the implant body rotated to the implanted orientation;
• a second set of aligned teeth formed on the implant body adjacent the other sidewall surface for frictionally engaging the surface of the one vertebral body with the implant body rotated to the implanted orientation;
• an anchoring member fixedly connected to the implant body adjacent to the first set of teeth and extending beyond the first set of teeth;
• and
• a bone piercing portion of the anchoring member spaced from the implant body and extending toward the other sidewall surface to a position generally between the first and second sets of teeth so that as the implant body and anchoring member fixed thereto are rotated from the insertion orientation to the implanted orientation the second set of aligned teeth engage the surface of the one vertebral body prior to the anchoring member and the first set of aligned teeth.

A spinal implant for being secured between adjacent vertebrae, the spinal implant comprising:

• an implant body configured for being inserted between adjacent vertebral bodies in an insertion orientation and rotated between the vertebral bodies to a secured, implanted orientation;
• outwardly facing sidewall surfaces of the implant body configured to provide low-friction engagement with surfaces of the adjacent vertebral bodies with the implant body in the insertion orientation;
• upper and lower surfaces of the implant body having teeth for frictionally engaging the surfaces the adjacent vertebral bodies with the implant body rotated to the secured, implanted orientation;
• and
• an anchoring member fixedly connected to the implant body and configured to extend beyond the teeth formed on one of the implant body upper and lower surfaces for penetrating the surface of one of the vertebral bodies as the implant body is rotated to the secured, implanted orientation.

A method of securing an implant device between adjacent vertebral bodies, the method comprising:

• inserting an implant body between the adjacent vertebral bodies so that opposite, substantially smooth surfaces of the implant body engage corresponding surfaces of the adjacent vertebral bodies;
• rotating the implant body in the invertebral space between the adjacent vertebral bodies;
• engaging the surfaces of the adjacent vertebral bodies with teeth of the implant body as the implant body is rotated in the intervertebral space;
• and
• piercing the surfaces of the vertebral bodies with anchoring members secured to the implant body and extending beyond the teeth thereof as the implant body is rotated in the intervertebral space.
