  • Patent number: 10568796
    Abstract: A wearable apparatus comprises a passive artificial knee that comprises first and second links coupled at a knee joint, a passive compressive force generator coupled to the second link, and a release mechanism coupled to the first link. When an angle of the first and second links is less than a toggle angle, the release mechanism locks in a first operational mode, and the force generator compresses, resisting flexing of the second link. When the angle is larger than the toggle angle, the force generator decompresses and encourages flexion of said second link. When the force generator is extended and said compressive force is small, the release mechanism moves into a second operational mode, wherein the force generator neither resists nor encourages extension and flexion of said second link from said first link. The wearable apparatus comprises an exoskeleton trunk configured to couple to an upper body of a user.

  • Patent number: 10561507
    Abstract: Methods and systems for assisting hemiplegic and hemiparetic patients are described herein. A wearable gripper system assists a user with one functional hand to independently perform basic tasks. A wearable gripper is located on the forearm above a disabled hand. The user controls the wearable gripper easily and intuitively based on gestures measured by an instrumented wristband device. Movements detected at the functioning wrist and forearm are translated into the motion control commands communicated to the actuators of the wearable gripper. In this manner, the wearable gripper assists the user to manipulate objects in lieu of the disabled hand. In some embodiments, a number of conductive, stretchable string sensors are wrapped around the hand of a user to estimate wrist and hand motion. In some embodiments, a gripper actuator includes two or more fingers, each having a location dependent shape profile and compliance to accommodate different manipulation tasks.

  • Patent number: 10555822
    Abstract: A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

  • Patent number: 10531966
    Abstract: The present invention relates to a prosthetic leg for those having a femoral amputee, namely those having an above the knee stump, where certain movements can be difficult to perform. Known prosthetic knee joints that are weight-activated cannot substantially assist short-stumped individuals. The weight placed on the toe will typically cause disengagement of any stance mode there otherwise might be. The invention provides a solution to the problems addressed above. The present invention seeks to provide an improved mechanically operated prosthesis for a femoral amputee. The invention also provides an improved electrically-operated prosthesis for a transfemoral amputee.

  • Patent number: 10507112
    Abstract: An anchor for securing an implant within bone. In one embodiment, the anchor is used to aid in securing an acetabular cup within an acetabulum. The anchor may be implanted within an ischial defect of the pelvis, and is attached to an outer surface of the acetabular cup shell. The anchor is made at least in part of, and may be made entirely of, a porous metal material to facilitate the ingrowth of surrounding bone into the anchor for osseointegrating the anchor into the surrounding bone. The anchor may be secured to the acetabular shell by a screw fastener or by cement, for example. The anchor may be secured to the acetabular shell before the anchor and the acetabular shell are together implanted into the acetabulum, or the anchor may be implanted into the ischial defect, followed by seating the acetabular shell in the acetabulum and then securing the acetabular shell to the anchor.

  • Patent number: 10485682
    Abstract: In some embodiments of a prosthetic or orthotic ankle/foot, a prediction is made of what the walking speed will be during an upcoming step. When the predicted walking speed is slow, the characteristics of the apparatus are then modified so that less net-work that is performed during that step (as compared to when the predicted walking speed is fast). This may be implemented using one sensor from which the walking speed can be predicted, and a second sensor from which ankle torque can be determined. A controller receives inputs from those sensors, and controls a motor's torque so that the torque for slow walking speeds is lower than the torque for fast walking speeds. This reduces the work performed by the actuator over a gait cycle and the peak actuator power delivered during the gait cycle.
