  • Patent number: 9044159
    Abstract: Changes in the volume of residual limbs on which prosthetic sockets are worn can be measured based on bioimpedance measurements along one or more segments of the limb. A current at an appropriate frequency (e.g., in the range from 1 kHz to 1 MHz) is injected at two current electrodes that contact the skin of the residual limb. The voltage at the voltage electrodes disposed between the current electrodes is measured and using an appropriate model, the change in the segmented volume of the limb can be determined during periods of different activity and at different times during the day. This information can be used for assessing the fit of the socket and can also provide a feedback signal for automatically controlling volume management devices, to ensure a more comfortable fit when the volume of the limb is changing.

    Abstract: The unique advantages of computer-controlled fabrication of a patient-specific orthotic device using an automated fabrication machine capable of following computer instructions to create 3D surface contours and new developments in non-invasive three-dimensional (3D) scanning have made it possible to acquire digital models of freeform surfaces such as the surface anatomy of the human body and to then fabricate such a patient-specific device with high precision. Such a patient-specific device brings significant improvement in patient-specific fit, comfort, and function of medical devices (and, in particular, to orthoses that require a close fit to the wearer's body to act effectively). The combination of these two technologies is ideally suited for the development of patient-specific orthotic devices. A patient specific ankle-foot orthotic device using this technology is disclosed. This exemplary device is used to help stabilize the ankle-foot region, for example, in patients with impaired gait.

  • Publication number: 20140081421
    Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

  • Patent number: 8674838
    Abstract: A walking assist device which allays uneasiness felt by a user when a wearable device actively applies torque to a leg. A walking assist device comprises a controller, a headphone and a wearable device attached to left and right legs. The wearable device has a sensor that detects motion of the user's leg and a motor that applies torque to a joint of the user's leg. The controller controls the wearable device such that the joint angle of the user follows a target pattern which represents time-dependent changes of a target joint angle. The controller specifies a change timing at which a time-dependent change of the target joint angle in the target pattern meets a predetermined condition, and informs the user, before the specified change timing, that the change timing is arriving. The uneasiness felt by the user when an actuator actively applies torque to the leg joint is allayed by informing the user of the motion before the actuator performs that motion.

  • Patent number: 8628585
    Abstract: In a lower limb prosthesis an ankle unit has a combination of an hydraulic piston and cylinder assembly providing a continuously damped range of ankle flexion and a resilient telescopic shock absorber. The damping resistance of the piston and cylinder assembly is the predominant resistance to ankle flexion and is provided by a piston which is axially moveable in a cylinder centered on the shin axis. The wall of the cylinder has a cylindrical outer bearing surface for a sleeve which is translationally displaceable relative to the piston and cylinder assembly according to the axial load, the sleeve being resiliently mounted by a compression spring which extends axially within the sleeve and has an integral end portion forming an upper bulkhead of the cylinder. The sleeve is also rotatable on the cylinder wall, the spring providing torsional resistance.

  • Patent number: 8601666
    Abstract: An anatomical socket is fashioned to attach to an amputated limb, which can be a median between the amputated limb and the prosthesis device. The method produces, based on specific measurements of a user, an anatomical socket that provides the user with cosmesis, a greater range of motion, a better gait and comfort. The socket has a low upper rim to allow for the greatest mobility of the hip joint. The socket is produced of a durable and smooth plastic. The socket fits in a secure, yet removable manner to the prosthesis. The method disclosed herein takes precise measurements of the wearer's limb to provide for optimal fitting and comfort.

  • Patent number: 8598815
    Abstract: Torsional loads can impart painful and potentially injurious shear stresses upon residual limb soft tissues in lower limb amputees. To protect the soft tissues, a controllable transverse rotation adapter (TRA) has been developed that permits rotation of the prosthetic socket relative to the prosthetic foot, relieving some of the rotational loads experienced by the residual limb, and controlling either the stiffness resisting the transverse rotational torque, or the torque. This TRA uses series elastic actuator (SEA) technology and includes a prime mover, a speed reduction device, and a torsion spring mounted in series. By measuring a displacement of the spring (e.g., using a strain gauge), motor current, and the motor shaft position, the load torque and position can be used to calculate actual stiffness or applied torque. The motor position is then adjusted relative to the load, to control the effective stiffness or torque.
