Suspended sleeve assembly comprising a compression sleeve and a suspension stand
A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.
METHOD FOR CONTROLLING AN ORTHOPEDIC DEVICE AND ORTHOPEDIC DEVICE
The invention deals with a method for controlling an orthopedic device, the method comprising the following steps of: —Providing input signals, —Using said input signals as input variables of a musculoskeletal model, —Determining feedback signals using said musculoskeletal model, —Transmitting said feedback signals to said user of said orthopedic device.
Breathable residual-limb socket system
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.
SENSOR FOR PROSTHETIC CONTROL
A sensor assembly for a prosthetic or orthotic device (POD) may include a housing and a support. The housing may be attached with the POD. The support may be moveably connected with the housing such that the support may move relative to the housing. The support may form an enclosure with the housing. Within the enclosure, the sensor assembly may include one or more sensors and a circuit board. The one or more sensors may include one or more of an inertial measurement unit, an electromyography sensor, or a distance sensor such as a magnetic sensor and a magnet. The circuit board may be attached with the support and in electrical communication with the plurality of sensors. Movement of the support may cause the sensors to move which may be detected for control of the POD. The sensor assembly may be attached to an arm or other prosthetic socket for detection of natural limb movements.
System and method for providing biomechanically suitable running gait in powered lower limb devices
Systems and methods for a running controller for a lower limb device including at least a powered knee joint are provided. The method includes collecting real-time sensor information for the lower limb device and configuring the lower limb device to a first state in a finite state model for an activity mode including the running mode. The method further includes, based on the sensor information, transitioning the lower limb device from a current state to a subsequent state in the finite state model for the detected mode when a pre-defined criteria for transitioning to the subsequent state is met, and repeating the transitioning until the activity mode changes. In the system and method, the finite state model includes at least one stance state and at least one swing state, where the at least one stance state includes at least one absorption state and at least one propulsion state.

PUMP SYSTEM
A vacuum suspension system includes a foot cover having a heel portion and a pump system located in the heel portion. The pump system includes upper and lower sections arranged to move in an axial direction relative to one another and a pump mechanism operatively connected to and positioned between the upper and lower sections. When the heel portion is loaded in stance the pump mechanism moves from an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, to an expanded configuration in which the volume of the fluid chamber is increased.

ACTUATOR-DAMPER UNIT
An actuator-damper unit for use in orthotic or prosthetic devices. The actuator-damper unit includes a housing which may be fastened on the orthotic or prosthetic device and in which a cylinder is formed. A first piston is displaceably mounted in the cylinder and is coupled to a piston rod. The piston rod is disposed, via a first end, on the first piston and may be coupled, via a second end, to the orthotic or prosthetic device. The first piston separates two fluid chambers in the cylinder from each other and forms a piston-cylinder unit, wherein at least one further piston is coupled to the first piston in order to form at least one further, variable-volume fluid chamber.
SYSTEM AND METHOD FOR COORDINATED MOTION AMONG HETEROGENEOUS DEVICES
A movable table may be configured to support a patient. The movable table may comprise a communication interface configured to communicatively couple with a medical device. The movable table may also comprise one or more processors and a non-transitory machine-readable medium comprising a plurality of instructions which, when executed by the one or more processors, cause the one or more processors to perform operations. The operations may include transmitting, via the communication interface and to the medical device, information relating to a planned motion of the movable table and receiving, via the communication interface and from the medical device, a response to the information relating to the planned motion of the movable table. Based on the response received from the medical device, the operations may include selectively causing performance of the planned motion of the movable table.
