  • Patent number: 11382775
    Abstract: An adjustable prosthesis system for a residual limb includes: an adjustable outer shell surrounding the residual limb having a plurality of overlapping flaps, a top opening along a top edge extending around the outer shell, a bottom having a bottom edge opposite the top edge and extending around the bottom, a first side, and a second side having an adjustable width, and a plurality of adjustable overlapping side ends, some of which overlap and some do not, extending from the top edge to the bottom edge; a base adjacent the bottom of the outer shell and connected to it; and a closure component attached to the outer shell to compress the residual limb. Tightening the closure component applies a pulling force to at least one of the first side and the second side, thereby causing a reduction in width of a discontinuity and increased overlap of the side ends.

  • Patent number: 11369503
    Abstract: Systems, methods, and apparatus provide artificial knees. Artificial knees include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to the thigh link, and a compression spring rotatably coupled to the thigh link and coupled to a second end of shank link with a second end of the compression spring. During a first range of motion, the compression spring is configured to provide an extension torque between the thigh link and the shank link causing the artificial knee to resist flexion. After the first range of motion, the compression spring is configured to provide a flexion torque between the thigh link and the shank link encouraging the artificial knee to flex resulting in toe clearance during the swing phase. During the swing phase, the compression spring provides no torque between the thigh link and the shank link.

  • Patent number: 11229531
    Abstract: A method for controlling a damping modification in an artificial knee joint of an orthosis, an exoskeleton, or a prosthesis. The artificial knee joint has an upper part pivotally connected to a lower part A resistance unit is secured between the upper part and the lower part in order to provide a resistance against a flexion or extension. The resistance unit is paired with an adjustment device to modify the resistance when a sensor signal of a control unit paired with the adjustment device activates the adjustment device. The flexion resistance is reduced for the swing phase. A curve of at least one load characteristic is detected when walking or standing; a maximum of the load characteristic curve when standing is ascertained; and the flexion damping is reduced to a swing-phase damping level during the standing phase when a threshold of the load characteristic below a maximum is reached.
