Abstract: A hinged knee prosthesis comprises a tibial component and a femoral component. The tibial component is configured to attach to a tibia. The tibial component has a bearing surface. The femoral component is configured to hingedly attach to the tibial component and rotate relative to the tibial component. The femoral component comprises a medial condyle and a lateral condyle. The medial and lateral condyles have an eccentric sagittal curvature surface configured to rotate and translate on the bearing surface of the tibial component. A method of rotating a hinged knee through a range of flexion is provided. The method fixedly attaches a femoral component to a tibial component. Axial rotation of the femoral component is induced relative to the tibial component when the hinged knee is flexed.

Abstract: Embodiments of an artificial meniscus implant are disclosed herein. An artificial meniscus includes at least one circumferential fiber and at least one non-circumferential fiber embedded within an arc-shaped body. The non-circumferential fibers may form loops extending through a peripheral edge of the implant, and the circumferential fibers may extend out of anterior and posterior horns of the implant to terminate in ends that are configured for fixation to bone. The ends may be interconnected, and covered by horn extensions to protect the ends from wear at the bone interface. Methods of making and implanting artificial meniscus are also disclosed herein. The method of making includes stepwise molding, layering, and curing of polymer material around the circumferential fibers and sewing the non-circumferential fibers into the polymer material. Methods of implanting may include threading ends of circumferential fibers through first and second bone tunnels.

Abstract: An accommodating intraocular lens (IOL) is formed from an anterior or posterior half molded as a chambered, polymer sack with a mouth opening smaller than its largest width that is mated to another half molded as a pliable bowl having a rim larger than the rest of the half. The resulting shell has a seam that is parallel to and does not cross or touch the equator such that the IOL is asymmetric between its front and back. A circular depression around the optical axis can be made in the anterior and/or posterior half such that a surrounding capsular bag seals against the rim of the depression, and an interior of the depression(s) does not touch the capsular bag.

Abstract: Apparatuses, systems, and methods for providing improved intraocular lenses (IOLs) and other refractive treatment modalities involve fabricating the IOL or developing the treatment based on a refractive profile. Exemplary techniques include obtaining a base wavefront power profile corresponding to a theoretical lens, adding a second wavefront profile defined by the combination of one or more zones described by a cosine function to obtain a final wavefront power profile, determining a refractive profile based on the final wavefront power profile, and fabricating the intraocular lens or determining the treatment based on the refractive profile.

Abstract: Optoelectronic retinal prostheses transduce light into electrical current for neural stimulation. A novel optoelectronic pixel architecture is presented comprising a vertically integrated photo junction field-effect-transistor (Photo-JFET) and neural stimulating electrode. Experimental measurements demonstrate that optically addressed Photo-JFET pixels utilize phototransistive gain to produce a broad range of neural stimulation current and can effectively stimulate retinal neurons in vitro. The compact nature of the Photo-JFET pixel can enable high resolution retinal prostheses with a theoretical visual acuity ˜20/60 to help restore vision in patients with degenerative retinal diseases.
