  • Patent number: 10226347
    Abstract: Systems, devices, and methods are described for providing orthopedic implants that reduces the negative effects of stress shielding on surrounding bone structure. The orthopedic implants are comprised of two portions, a shell portion that forms an articulation interfaces and an intermediate portion that forms a bone interface. The shell portion is designed to reduce absorption of articulation forces and evenly distribute incident forces to the intermediate portion. The intermediate portion is designed to form a strong interface with native bone and transmit forces from the shell into the bone.

  • Patent number: 10149768
    Abstract: Knee prostheses that more faithfully replicate the structure and function of the human knee joint in order to provide, among other benefits: greater flexion of the knee in a more natural way by promoting or accommodating internal tibial rotation, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a natural way. Such prostheses may include an insert component disposed between a femoral component and a tibial component, the insert component featuring, among other things, a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes. Other surfaces can be shaped using iterative automated techniques that allow testing and iterative design taking into account a manageable set of major forces acting on the knee during normal functioning, together with information that is known about natural knee joint kinetics and kinematics.

  • Patent number: 10052195
    Abstract: An implantable ophthalmic device with flexible, fluid-filled membranes provide dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia without moving parts or reducing the amount of transmitted light. Actuating the device causes the fluid-filled membrane to change curvature, which produces a corresponding change in optical power. For instance, squeezing the edge of the membrane causes the center of the membrane to bulge by an amount proportional to the squeezing force. Alternatively, heating or applying a voltage to the membrane may cause the liquid in the membrane to undergo a phase transition accompanied by a corresponding change in volume that causes the membrane to inflate so as to change the optical power of the device.

  • Patent number: 10052210
    Abstract: Dimensionally adjustable spinal prostheses are adjustable in an axial or superior to inferior dimension such that spinal prostheses may assume variations in height. The height adjustable spinal prostheses are characterized by first and second portions that are configured for adjustable coupling with one another. Spatial adjustment between the first and second portions is provided by an adjustment assembly. The adjustment mechanism preferably, but not necessarily, provides infinite adjustment over a minimum prosthesis height to a maximum prosthesis height. In one form, first and second ends of the height adjustable spinal prostheses are configured to receive an endplate. The endplates aid in attachment and/or anchoring of the spinal prosthesis within the spine. The endplates may be fashioned in various configurations such as circular or anatomical. In one form, the adjustment assembly utilizes rotational motion for varying the axial position of one prosthetic portion relative to the other prosthetic portion.

  • Patent number: 10039635
    Abstract: An intraocular lens includes an optic, which includes a first lens having a first optical axis for alignment with an optical axis of the human eye having a macula; and a second lens having a second optical axis. The second optical axis and the first optical axis enclose an angle between 0.5 and 10 degrees. The first and second lens are arranged next to one another in a direction transverse to the first optical axis to provide no overlap in a direction along the first optical axis such that the first lens and the second lens each, independent from one another, image onto the macula of the eye. The angle and a direction of the second optical axis are chosen such that the second lens images onto a functional part of the macula of the human eye, which functional part is not compromised by a defect, such as a scotoma.

  • Patent number: 10039648
    Abstract: An intervertebral implant system installable between a pair of vertebrae. The implant includes a spacer that fits between the pair of vertebrae with a screw aperture for passage of a first screw and angled to orient the first screw into a first vertebrae at an angle relative to the rear sidewall of the spacer so that the first screw will enter an endplate of the first vertebrae. A plate is installable onto the rear sidewall of the polymeric spacer. The plate includes an angled screw aperture that is aligned with the screw aperture of the spacer when the plate is installed on the spacer. An elevated screw support extends upwardly or downwardly from the plate so as to extend opposite the direction of the angled screw aperture. The elevated screw support locates a second screw to enter a second vertebrae through an anterior surface of the second vertebrae.
