Abstract:
1. A spinal implant comprising: first spinal attachment member, having a top surface and an inner surface, for attaching to a first spinal portion; second spinal attachment member, having a bottom surface and an inner surface, for attaching to a second spinal portion; and a post-implantation variable dimension device disposed between said first and second spinal attachment members, which is operable after completing surgery in which said spinal implant was installed into a patient, to cause relative movement between said first and second spinal attachment members; wherein said post-implantation variable dimension device comprises threaded shafts, which do not have a common longitudinal axis, driven by a gear train activated by a remotely controlled motor, wherein said first and second spinal attachment members are each tapped with threaded through holes to accept said threaded shafts to allow said threaded shafts to move through said top surface of said first spinal attachment member and said bottom surface of said second spinal attachment member and to thereby move said first spinal attachment member with respect to said second spinal attachment member.
