A support structure, a prosthesis component, and a method for producing a prosthesis component.

Dynamic support apparatus and system

A dynamic support system includes a control system for controlling inflation and deflation of at least one actuator having an inlet connectable to the a control unit of the dynamic support system. The control unit may be in communication with a sensor and may control inflation and deflation of the at least one actuator in response to information provided by the sensor.

Prosthetic liner and method for making the same

A method for making a prosthetic liner includes the steps of providing a textile sleeve, applying an uncured silicone material onto an inner surface of the textile sleeve and impregnating interstices of a high-density knit structure of the textile sleeve. The silicone material is a fast-cure silicone material arranged to reach at least 90% cross-linking faster than conventional silicone material. The silicone material is preferably limited to the inner surface of the textile sleeve, whereas the outer surface is devoid of the silicone material. The silicone defines an inner layer forming the interior surface of the liner, and the outer surface of the textile sleeve forms the exterior surface of the liner. A thickness of the liner from the interior surface of the liner to the inner surface of textile layer consists of the silicone of the inner layer.

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.

MECHANISMS AND METHODS FOR THE DESIGN AND FABRICATION OF A MECHANICAL INTERFACE BETWEEN A WEARABLE DEVICE AND A HUMAN BODY SEGMENT
20220133173 · 2022-05-05 · ·

The system includes an instrument for determining the anatomical, biomechanical, and physiological properties of a body segment that includes one or more force sensitive probes is provided. A human operator actuates one or more force sensitive probes, wherein the force sensitive probes are positioned at the surface of the body segment. The operator pushes on the force sensitive probes with varying force applied on the body segment to measure tissue deflection forces. The instrument may include one or more of gyroscopes, accelerometers, and magnetometers capable of measuring changes in tissue deflection caused by the force sensitive probes relative to a grounded reference frame in 3-D space, wherein the tissue deflection force data and the change in tissue deflection data are used to compute segment tissue viscoelastic properties. The instrument may also be untethered or wireless.

Knitted interface

A knitted interface comprises a knitted structure formed from a plurality of elastomeric polymer filaments having a plurality of interstices permitting a transfer of air therethrough. The elastomeric polymer filaments may have a solid or hollow cross-section. The interstices vary in shape and size according to a knit density of the knitted structure upon movement or radial distension of the knitted interface. The elastomeric polymer filaments may be made from silicone.

Electromyography sensor

An electromyography (EMG) sensor for a wearable device, such as a prosthetic device attachable to a residual limb, includes a flexible substrate comprising an elongated portion and an electrode portion. At least two electrodes are disposed at a surface of the electrode portion of the flexible substrate, and leads from the at least two electrodes extend through the elongated portion of the flexible substrate.

HANDS-FREE APPARATUS TO APPLY A LINER TO AN AMPUTATED APPENDAGE
20220133511 · 2022-05-05 ·

An apparatus for use to apply a liner to an appendage of a user includes a base member and a plurality of arms mounted to the base member. Each arm can include a rotating member, such as a roller ball, coupled to a top end of the arm. The plurality of arms can extend from the base member in a generally upright position and can support the liner thereon in an inside out position so that the application of downward pressure by the appendage of the user within the plurality of arms permits the arms to flex outward, thereby allowing the plurality of arms and roller balls to slide the liner around the appendage of the user. The height of the apparatus can be adjustable by forming each arm in two or more pieces having a height-adjustable engagement between the pieces. Such a configuration further allows for compact disassembly.

Method For Producing A 3-Dimensional Object And Apparatus Therefor
