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

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.

A prosthetic attachment system and corresponding lock assembly for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket. The lock assembly includes a base arranged to be supported by the distal end of the prosthetic socket, and defining a bore. An attachment pin is arranged to be carried by the prosthetic liner and insertable through the bore. A lock mechanism is arranged to be carried by the base and is rotatable about a rotation axis. The lock mechanism includes a control knob extending outwardly from a side of the base. The attachment pin is arranged to interact with the lock mechanism cause the control knob to spin at least one projection of the control knob about the rotation axis.

A prosthetic liner for use with a prosthetic socket that has a thermoplastic elastomeric (TPE) layer that is in contact with the amputee's residual limb. The TPE layer is not uniform in thickness but has ridges to extend circumferentially around the TPE layer. A fabric layer covers the outer surface of the TPE layer conforming to the ridges and is used as a substrate to form a mechanical bond to an outer seal layer. The outer seal layer is formed by applying an uncured material to the fabric around the ridges thereby creating an air tight boundary layer when inserted into a socket. When vacuum is applied the air is evacuated from the volume below the seal layer.

An interchangeable lock-pump prosthetic system that includes a universal dummy, vacuum pump, and mechanical lock. Each of the three objects have similar geometries for the purpose of fitting into a prosthetic, whereupon a user may for instance, swap the vacuum pump with the lock, depending on the needs of the user and without changing to a separate prosthetic. The universal dummy is an inactive component and acts as a placeholder during manufacturing of the socket, for the eventual inclusion of the vacuum pump or mechanical lock. The vacuum pump is a pressure dependent object that acts to remove any residual air between the socket and the elastomeric liner. The lock takes advantage of a mechanical locking pin which receives a properly configured liner, thus securing the user within the prosthetic socket.

The invention relates to a prosthetic socket system having: a dimensionally-stable outer socket (10) having a proximal insertion opening (11) and a distal end region (12), on which outer socket a fastening element (13) for a distal prosthetic component is arranged; and a prosthetic liner (20) that can be secured in the outer socket (10) and has a distal sealing cap (21), a supporting element (30) being arranged in the outer socket (10) proximally to the distal end region (12) of the outer socket (10) and having a recess (40) for an osseointegrated coupling element (50).

A prosthetic device includes a socket, fasteners, and a pylon. The socket defines a cavity configured to receive a residual limb of a user. The socket includes a base defining multiple blind-holes. Each of the fasteners are configured to be received within a corresponding one of the blind-holes. The fasteners each include internal threads. The pylon includes through-holes that are aligned with a corresponding one of the blind-holes. The pylon is configured to be directly coupled with the base of the socket through externally threaded fasteners that extend through the through-holes and threadingly couple with the internal threads of the plurality of fasteners.

Disclosed herein are devices, systems, and methods for measuring socket fit in lower limb prostheses and detecting motion of a residual limb relative to a prosthetic socket. Also disclosed herein are methods for developing a socket-fit detection system for sock management that can be applied to adjustable socket systems.

A prosthetic socket system includes a prosthetic lock assembly having a lock body defining a pin hole adapted to receive an attachment pin, and a locking device in the lock body. The locking device is engageable with the attachment pin to unidirectionally lock the attachment pin in the lock body while permitting insertion of the attachment pin in the lock body. A valve assembly is positioned in the lock body that is movable between a closed position and an open position in which the valve assembly is unsealed so that air moves into the lock body via the valve assembly. A release mechanism positioned in the lock body is arranged to both release the locking device from the attachment pin and move the valve assembly to the open position by translating the locking device in the lock body.

A prosthesis suspension system comprises a socket for receiving a residual limb, a locking liner having a locking pin for attaching the liner to the socket and a sealing cap disposed between the locking line and the socket. The system further comprises a gap between a skirt of the sealing cap and an interior wall of the socket in which the skirt of the sealing cap is able to move between first and second positions.
