  • Patent number: 11324612
    Abstract: A liner defines a pouch, an opening, a cup, and a first ring positioned on the pouch distal to the opening. The pouch is air-permeable and defines an internal volume for receiving a residual limb. The opening defined by the pouch provides access to the internal volume. The cup is air-impermeable and is positioned on the pouch distal to the opening. The liner is combined with an adapter for connecting a residual limb to a prosthetic limb. The adapter has a socket for receiving the cup, at least one hole positioned within the socket for drainage therefrom and sleeve extending from the socket and surrounding a central space. The adapter also has at least one vent positioned in the sleeve and overlies the air permeable material.

  • Patent number: 11311393
    Abstract: A universal digit is formed to be attachable to the residual digit of a patient, and to have a lockable joint, so as to provide considerable utility and flexibility. The structure of the joint member allows the universal digit to be easily adjusted and manipulated so that the extension portion can be locked into multiple positions by easily manipulating adjustment buttons. The extension is rotatable about a first longitudinal axis, and is further rotatable about a transverse axis which is perpendicular to the longitudinal axis. The joint structure thus has three dimensions of movement and provides a significant number of diverse options for positioning of the extension. Unique locking mechanisms within the various structures allow the universal digit to be rigidly held in the desired position, thereby increasing the utility for a patient/user.

  • Patent number: 11273050
    Abstract: An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

  • Patent number: 11273060
    Abstract: An artificial foot and ankle joint consists of a curved leaf spring foot member having a heel extremity and a toe extremity, and a flexible elastic ankle member that connects the foot member for rotation at the ankle joint. An actuator motor applies torque to the ankle joint to orient the foot when it is not in contact with the support surface and to store energy in a catapult spring that is released along with the energy stored in the leaf spring to propel the wearer forward. A ribbon clutch prevents the foot member from rotating in one direction beyond a predetermined limit position. A controllable damper is employed to lock the ankle joint or to absorb mechanical energy as needed. The controller and sensing mechanisms control both the actuator motor and the controllable damper at different times during the walking cycle for level walking, stair ascent, and stair descent.

  • Patent number: 11224527
    Abstract: An interchangeable lock-pump prosthetic system that includes a universal dummy, vacuum pump, and mechanical lock. Each of the three objects have similar geometries for the purpose of fitting into a prosthetic, whereupon a user may for instance, swap the vacuum pump with the lock, depending on the needs of the user and without changing to a separate prosthetic. The universal dummy is an inactive component and acts as a placeholder during manufacturing of the socket, for the eventual inclusion of the vacuum pump or mechanical lock. The vacuum pump is a pressure dependent object that acts to remove any residual air between the socket and the elastomeric liner. The lock takes advantage of a mechanical locking pin which receives a properly configured liner, thus securing the user within the prosthetic socket.

  • Patent number: 11207014
    Abstract: Automatic electromyography (EMG) electrode selection for robotic devices is disclosed. A plurality of signals from a corresponding plurality of sensors coupled to a skin of a user is received. For each pair of at least some pairs of the plurality of sensors, a sensor pair signature is generated based on differences in signals that are generated by the respective pair of sensors. Each of the sensor pair signatures is compared to a predetermined sensor pair signature to identify a particular pair of sensors. A signal difference between two signals generated by the particular pair of sensors is subsequently utilized to generate a command to drive a motor.

  • Patent number: 11202716
    Abstract: A prosthetic system includes a prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket, and a valve assembly. The valve assembly is arranged for regulating fluid communication between an interface region defined between the prosthetic liner and the residual limb and a suspension chamber defined between the prosthetic liner and the prosthetic socket. A vacuum in the suspension chamber selectively moves the valve assembly between a closed position in which the valve assembly fluidly separates the suspension chamber from the interface region, and an open position in which a portion of the vacuum in the suspension chamber draws fluid from the interface region via the valve assembly into the suspension chamber.
