  • Prosthetic liner
    Patent number: 11123203
    Abstract: A prosthetic liner includes a flexible elongate, generally conical body portion formed from an elastomeric material. The body portion defines an inner surface, an outer surface forming a liner profile between a distal end and a proximal end, and an axis extending between the distal and proximal ends. At least one seal element extends circumferentially about the axis and protrudes radially outward a distance from the liner profile. The at least one seal element has a seal height defined between the liner profile and a radially outward end of the at least one seal element. The seal height varies circumferentially about the axis between a first seal height and a second seal height.

  • Electromyography with prosthetic or orthotic devices
    Patent number: 11051957
    Abstract: Systems, devices and methods for control of a prosthetic or orthotic device (POD) based on electromyography (EMG) signals are described. The POD may be a lower or upper limb POD having one or more joints. One or more EMG sensors may detect the EMG signals. The EMG sensors may be external, subcutaneous, intraperitoneal, epimysial, intramuscular, or other types. Control of the POD may be based on EMG and non-EMG signals, such as velocity, acceleration, position, force, etc. Voluntary and/or automatic control may be implemented, for example with voluntary muscle contractions and/or data based on velocity, acceleration, position, force, etc. In some embodiments, the neutral position of an ankle POD is adjusted based on EMG signals.

  • Prosthetic and orthotic devices and methods and systems for controlling the same
    Patent number: 11020250
    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.

  • Body interface
    Patent number: 11000439
    Abstract: A body interface comprises a panel, and a lumbar support and may be configured to attach to an exoskeleton such as a leg/hip assist mechanism. The body interface has an adjustable tension provided by either a tensioning device or by the properties of materials in the panel and the lumbar support. Tension in the body interface allows the lumbar support to comfortably and dynamically contact a user's body while the panel cooperates with the leg/hip assist mechanism. First and second arms may extend from lateral portions of the panel to define with first and second belt members a circumference around the user.

  • Orthopedic device
    Patent number: 10993826
    Abstract: An orthopedic system includes a base shell forming an opening over a dorsal aspect thereof and a dorsal shell contoured to generally correspond to the opening of the base shell. The base shell has a proximal member and a distal member connected to the proximal member, each has a semi-rigid shell configuration to protect and support a lower leg, an ankle, or a foot of a user when received in the orthopedic system. A flexible toe portion is attached to a distal terminal end area of the distal member and formed of a different material than the distal member. The flexible toe portion is arranged to terminate above an upper surface of the user's toes and to flex relative to the distal member and the toes so as to reduce the likelihood of pressure points on the toes from the distal member.

  • Adjustable socket system
    Patent number: 10993819
    Abstract: An adjustable socket system includes a plurality of shell components and longitudinal supports connected to a base and is movable between an open configuration to loosen the fit of the adjustable socket system, and a closed configuration to secure the fit of the adjustable socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the adjustable socket system to the closed configuration.

  • Graphical user interface of mobile device for improving interaction with a prosthetic or orthotic device
    Patent number: 10987029
    Abstract: Systems and methods for improving an interaction between a prosthetic and/or orthotic device (POD) and a user of the POD are described. In some cases, the POD monitors various parameters during gait and communicates the gait parameters to a remote monitoring device. The remote monitoring device can analyze the gait parameters in real-time to provide various indications of user-POD interactions including, but not limited to, symmetric weight bearing, rolling over the toe, sitting down, stair descent, and/or stair ascent. The remote monitoring device can further provide indications to improve the user-POD interactions.

  • Variable stiffness mechanism and limb support device incorporating the same
    Patent number: 10980648
    Abstract: A limb support device includes a variable stiffness mechanism. The limb support device can be an orthotic or prosthetic device. The variable stiffness mechanism can include, for example, a rate-sensitive or speed-dependent material or a damping mechanism. The variable stiffness mechanism causes the limb support device to exhibit different properties when the user of the limb support device is walking at high or fast walking speeds compared to low or slow walking speeds. The limb support device can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

  • Cervical collar
    Patent number: 10945872
    Abstract: A cervical collar having an anterior component including a main support, an intermediate support pivotally connecting to the main support at a rear portion of the anterior component, and forming a frontal opening with the main support. An adjustment mechanism connects the main support to the intermediate support and locks a position of the intermediate support relative to the main support at a front portion of anterior component. The adjustment mechanism has an actuator for disengaging the main support from the intermediate support at the front portion and permits the intermediate support to pivot relative to the main support at the rear portion to vary a height of the frontal opening. A posterior component of the cervical collar is adapted to provide improved anterior-posterior and lateral occipital support.

  • Prosthetic socket sealing system
    Patent number: 10945865
    Abstract: A prosthetic socket system includes a distal seal positionable between an interior surface of a prosthetic socket defining a pin bore and a distal end of a prosthetic liner carrying an attachment pin arranged to extend through the pin bore. The distal seal includes a base proximate to the attachment pin and defining an opening configured to receive and surround the attachment pin, a sealing portion extending distally from an outer radial portion of the base, and a variable clearance defined between the sealing portion and the base. The sealing portion is adapted to form a seal around the attachment pin and prevent fluid flow through the pin bore by deflecting relative to the base when the sealing portion engages the interior surface of the prosthetic socket.
