  • Patent number: 10327975
    Abstract: An exoskeleton can be reconfigured, adjusted and/or controlled on the fly utilizing devices which fall into three categories, particularly including a swappable unactuated leg, lockable transverse and coronal hip rotations, and software controlled free joints. More specifically, the first device allows for the creation of a modular joint system in which individual exoskeleton joints or limbs can be changed or swapped to optimize an exoskeleton for a particular user. The second device is concerned with mechanically controlling, such as locking and unlocking, joints thereby allowing, for example, an exoskeleton leg to pivot or not pivot in an axis that is not actuated. The third device allows an actuated exoskeleton joint to be adjusted on the fly using software to simulate a freely rotating joint. The various devices can be used either alone or in combination to enable any given exoskeleton to be appropriately reconfigured, such as when a patient advances during therapy.

  • 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.

  • Patent number: 8915968
    Abstract: Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

  • Patent number: 8906112
    Abstract: A prosthesis socket for receiving an amputation stump has at least one shell which has an arched, open cross-section, where the shell ends in the applied state overlap each other at least partially. At least one tensioning means is disposed on the shell to act in a circumferential direction for tensioning the shell ends relative to each other. The shell is being made of a dimensionally stable plastic having regions with varying elasticity. The proximal end of the socket is relatively more flexible. The inner surface of the socket includes a direction dependent surface to aid in holding the amputation stump. A connector for the distal prosthesis is preferentially positioned adjacent the patient's greater trochanter and is configured for pivotable bearing of the prosthesis with fixing devices to secure the orientation of the prosthesis relative to the socket.

  • Patent number: 8870801
    Abstract: A lower-limb joint orthosis includes a lower component supporting the foot region, an upper component attached to the lower-limb, and an orthotic joint coupling both components. The orthotic joint includes: a stator including some fluid chambers in which an MR fluid is enclosed; and a rotor including partition plates protruding into the respective fluid chambers. The stator includes a communication path between the anterior chamber and the posterior chamber. The rotor includes connection paths that connect the anterior chambers together, and connect the posterior chambers together. An electromagnet is placed on a side surface of the communication path so that a rotational resistance of the lower component and the upper component is adjusted by adjusting a magnetic force to control the viscosity of the MR fluid that flows through the communication path.

  • Patent number: 8858648
    Abstract: Disclosed are adjustable powered rehabilitation devices and methods for using the same to rehabilitate and/or train a user. The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.

  • Patent number: 8838263
    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.
