Abstract: A modular disc prosthesis system is provided that allows a disc prosthesis to be constructed, either pre- or intra-operatively, to have a desired degree of freedom or constraint when positioned between endplates of adjacent vertebrae. In particular, the components can be assembled to form a disc prosthesis having a center of rotation that is constrained or fixed such that, when the disc prosthesis is implanted between endplates of adjacent vertebrae, the adjacent vertebrae have one degree of freedom and move about a fixed center of rotation. Alternatively, one or more of the same components and one or more additional components of the system can be used to construct a disc prosthesis having a center of rotation that is unconstrained or that floats such that, when the disc prosthesis is implanted between the endplates of adjacent vertebrae, the adjacent vertebrae have multiple degrees of freedom and can move about a floating or moving center of rotation, i.e., a center of rotation that is not fixed.

Abstract: This invention is directed to an intra-operative technique to improve attachment and/or prevent expulsion of nucleus pulposus replacement/augmentation devices and/or to seal fissures in the annulus fibrosus of intervertebral discs.

Abstract: A system for use in preparing an articulating surface of a component of an orthopaedic implant is provided. The system includes a magnetorheological polishing fluid including a carrier fluid and a plurality of particles suspendable in said carrier fluid. The system also includes a vessel for containing the Magnetorheological polishing fluid. The system also includes a mechanism for delivering the fluid to form a polishing zone and a holder for securing the component and for moveably positioning the articulating surface of the component relative to the polishing zone. The system further includes a controller for determining the rate of material removal from the object, for determining the direction and velocity of movement of the polishing zone relative to the object and for determining the number of cycles of polishing required.

Abstract: Irradiating osteolytic regions with UVB light.

Abstract: An intracranial, light-emitting implant for providing therapy to a patient having Alzheimer's Disease.

Abstract: A distraction instrument distracts two adjacent vertebra segments to receive an artificial disc, the instrument including a measurement indication related to a distracted disc space. The measurement indication can be the force required to distract the disc space, the distance between the adjacent vertebra, the lordotic angle of a pair of vertebra defining the disc space, and the width of the disc space.

Abstract: A trial intervertebral disk implant includes a first plate, a second plate, adjacent to the first plate, a conformable layer between the first and the second plates, and a pressure sensor within the conformable layer. The pressure sensor measures a distribution of compression force exerted by the first and the second plates on the conformable layer. The trial implant includes indicating means for indicating a position of the first and the second plates relative to each other, and locating means, for locating a position of the trial implant relative to the vertebrae between which said trial implant has been placed. The trial implant further includes at least one retractable member, connected to at least one of the first and the second plates. The retractable member can be extended or retracted through an aperture defined by a surface of the plate that is proximal to an abutting vertebra.

Abstract: A hydrocephalus shunt has photocatalytic capabilities. The shunt is used to treat hydrocephalus by inserting into a human cranium a hydrocephalus shunt having a component having a surface. Thereafter, a reactive oxygen species is produced on the component surface. The component may be a catheter. The shunt may also include a light source.
