  • Patent number: 8790411
    Abstract: A femoral component of an artificial knee joint is configured with multiple different facets which are similar in size and shape for many different sizes, to simplify an associated method for forming a distal end of the femur to receive the femoral component. Jig embodiments are provided to form surfaces on a distal end of a femur to correspond with facets of the femoral component, with the same jig usable for femoral components of differing size. The femoral component includes medial and lateral condylar legs with a posterior facet of the femoral component exhibiting a negative angle relative to a central axis of the femur, to maximize contact and increase flexion of the artificial knee joint.

  • Patent number: 8709078
    Abstract: An improved prosthesis and method for stimulating vision nerves to obtain a vision sensation that is useful for the patient that has lost vision due to age-related macular degeneration (AMD) and retinitis pigmentosa (RP) and other diseases. The present invention utilizes infrared light to cause action potentials in the retinal nerves similar to those which result from rods and cones stimulated by visible light in healthy retinas. In some embodiments, the invention provides a pathway or “image pipe” for transmitting a stimulation pattern of infrared light from an external stimulator array through the eye and focusing the stimulation pattern of infrared light on the retina, especially the fovea. Some embodiments provide improved resolution down to a group of nerves, or even the individual nerve level, with sufficient energy density so as to cause a desired action potential.

  • Patent number: 8696755
    Abstract: A tibial component of an artificial knee joint is provided which cooperates with a femoral component to allow pivoting rotation of the artificial knee joint in either a clockwise or counterclockwise direction. The tibial component includes a plate with a tapered dovetail rib thereon which allows an insert to be removably secured thereto to act as a meniscal structure for the tibial component. The insert has a proximal surface with left and right wells therein that include valleys to guide rotation of one condylar leg of a femoral component while holding a second condylar leg of the femoral component within the other one of the wells, allowing pivoting rotation in either direction. A nesting of the insert into a portion of the plate minimizes an overall height of the tibial component and minimizing tibial bone resection, while providing a greater resistance to shear forces upon the knee joint.

  • Patent number: 8668744
    Abstract: A vacuum-assisted suspension device for a lower limb prosthesis secures the prosthesis to a residual body portion. Sandwiched between the residual body portion and an impermeable socket is a flexible liner made of an impermeable material that is porous to allow the transport of air and fluid directly away from the residual body portion to the outer surface of the liner. A fabric distribution layer is located over the liner and between the liner and the socket to allow transmission of such extracted air and fluid laterally over the liner to an evacuation port in the socket. The evacuation port has an associated one-way valve. During use, loading of the socket compresses the flexible liner and air is expelled via the evacuation port. When the load is removed, a vacuum is created directly between the residual body portion and the socket, the vacuum being maintained by the one-way valve.

  • Patent number: 8652210
    Abstract: Knee prostheses featuring components 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 at least accommodating internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. In a preferred embodiment, such prostheses include an insert component disposed between a femoral component and a tibial component, the insert component preferably featuring among other things a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes.

  • Patent number: 8628577
    Abstract: Improved methods and apparatuses for vertebral body distraction and fusion in accordance with various embodiments employ mechanisms for stabilizing a device so that the device can stay in the body and stably support the disc space during vertebral fusion following distraction of the adjacent vertebra by operation of the device. The device is inserted into the disc space and distracted from a compressed configuration to an expanded configuration to distract the disc space. Mechanisms for stabilizing the device in the expanded configuration constrain the device to zero degrees of freedom of movement to allow the device to stably support the disc space. A bone growth stimulant for promoting vertebral fusion can be inserted into an open space defined by the device, which continues to stably support the disc space during vertebral fusion.
