摘要： An intervertebral disc replacement device comprising a superior plate and an inferior plate, in which each plate contains one or more embedded magnets. The one or more magnets in the superior plate and the one or more magnet in the inferior plate are oriented such that a magnetic force exists between the one or more magnets in the superior plate and the one or more magnet in the inferior plate. In addition, an intervertebral disc replacement device comprising a superior plate and an inferior plate, in which each plate contains one or more embedded magnets, and the plates are designed to form an articulating surface. Further, an intervertebral disc replacement device comprising a superior plate, an inferior plate, and a spacer, in which each plate contains one or more embedded magnets, and the superior and inferior plates are designed to form articulating surfaces with the spacer.

摘要： Implant devices, and method of using the same, are provided. The implant devices have an articular end and a stem, the stem having an oval-shaped cross-section. The articular end has an upper surface, a side surface, and a lower surface. The upper surface and lower surface each intersect the side surface. The upper surface has a first surface curvature, a central surface curvature, and a second surface curvature. The stem extends from the lower surface in a direction away from the upper surface of the articular end.

摘要： Implant devices, and method of using the same, are provided. The implant devices have a head and a stem. The head has an upper surface, a perimeter surface, and a lower surface. The upper surface is blended into the perimeter surface. The perimeter surface is blended into the lower surface. The upper surface has a general shape of at least a portion of a superior articular surface of a talus and at least a portion of a medial articular surface of a talus. The stem has a cylindrical portion, which optionally has at least one circumferential groove.

摘要： A total hip replacement prosthesis that comprises an acetabular component and a femoral component. The acetabular component has a full or partial hemispherical shape, and comprises a shell and one or more magnets. The femoral component comprises a stem portion comprising a proximal end and a distal end, a neck portion comprising a tapered end and a base end that is joined to the proximal end of the stem portion, and a spherical head that is affixed to the tapered end of the neck portion and comprises one or more magnets. The acetabular component is configured to receive all or a portion of the spherical head of the femoral component. Further, the one or more magnets of the acetabular component and the one or more magnets of the spherical head of the femoral component are oriented to generate an attractive force therebetween.

摘要： Prosthetic implant devices and related methods are provided. The prosthetic implant devices includes an internal component and an external component. The internal component has an implant portion associated with one or more rare earth magnets. The internal component being of a size and shape suitable for surgical implantation into the residual limb of the amputee. The implant portion being of a size and shape suitable for surgical implantation into a bone within the residual limb of the amputee. The one or more rare earth magnets generating at least one magnetic field. The external component having a prosthetic connection associated with a magnetic element. The magnet element being in adaptable magnetic association with the at least one magnetic field generated by the one or more rare earth magnets.
