Abstract:
One embodiment of the present application includes a spinal disk prosthesis (30) with one end portion (32a) to form a load transmitting relationship with one vertebra of a patient's spine and another end portion (32b) to form a load transmitting relationship with another vertebra of the patient's spine. A tube (52) connects the end portions (32a, 32b) together and a damping material (60) is positioned inside the tube (52) . The end portions (32a, 32b) each include a magnet (40a, 40b) to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions (32a, 32b) to provide a magnetic bearing.
