Patent ID: 8206387

Claim:
An artificial spinal implant for insertion into an implantation space created between two adjacent vertebral bone masses, comprising: a housing including: an upper surface and a lower surface opposite said upper surface, said upper and lower surfaces being configured to contact and support the adjacent vertebral bone masses; a leading end for insertion first into the implantation space and a trailing end opposite said leading end; opposite sides from said upper surface to said lower surface, and from said leading end to said trailing end; a mid-longitudinal axis passing through said leading and trailing ends; a maximum width from one of said opposite sides to the other of said opposite sides; a height from said lower surface to said upper surface; a depth from said leading end to said trailing end, the maximum width of said housing being greater than each of the height and depth of said housing, said leading end being curved from said opposite side to said opposite side; and a hollow chamber; control circuitry in said hollow chamber; and a rechargeable power supply for energizing said control circuitry, said rechargeable power supply being configured for inductive coupling to an external power supply.
