Abstract: An intervertebral spacer having opposing plates seatable against opposing vertebral bones, separated by at least one spring mechanism, preferably a spirally slotted belleville washer having a wide end rigidly fixed to an upper plate and a narrow end rotatably mounted to a lower plate. The lower plate includes an inwardly deflecting central post extending upwardly from the inner surface of the lower plate, the post including a head that is received through a central opening in the narrow end of the washer so that the washer is restricted from angulation with respect to the lower plate, but allowed to rotate with respect to the lower plate so that the plates can rotate relative to one another. The plates can angulate relative to one another because the washer deflects under lateral deflection forces and return to its undeflected shape when the forces are relieved.

Abstract: A knee joint prosthesis includes femoral and tibial components, a bearing and a control arm. The bearing includes an inferior surface in sliding bearing engagement with the tibial component and a superior surface in articular bearing engagement with the femoral component. A notch extends into the posterior end of the bearing and a groove extends anteriorly from the notch in the inferior surface of the bearing. The posterior portions of the femoral component define a cam box having medial and lateral walls and a cam extending therebetween. The control arm is slidably engaged in the groove of the bearing and pivotally engage on the tibial component. The control arm further includes a post that extends into the cam box. The post includes a cam surface that engages the femoral cam to generate roll back of the femoral component on the bearing during flexion. Roll back substantially avoids climb of the femoral component on the bearing during flexion and hence reduces shearing forces on the post.

Abstract: The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee which utilizes a plurality of interspersed and alternating rotors and stators to shear magnetorheological fluid in gaps formed therebetween. Advantageously, by operating in the “shear mode” there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed—eliminating the need for a transmission—and also for a wide dynamic torque range. One embodiment of the invention allows the rotors and/or stators to close the gaps therebetween to create a frictional torque component, thereby forming a “hybrid” braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.
