A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

A flexible prosthetic liner having a proximal access opening for a stump of a limb and a distal end region as well as a flexible tension member which is arranged in the distal 5 end region on the prosthetic liner. The tension member is detachably fastened to the prosthetic liner by means of a closure system that can be actuated without a tool. A prosthetic shaft system may be formed by such a prosthetic liner and a prosthetic shaft.

A prosthesis stem includes a stem body for receiving an amputation stump and an insertion aid apparatus, which facilitates the insertion of the amputation stump into the stem body, wherein the insertion aid apparatus comprises an insertion inlay which is connected in the proximal edge region thereof to a holding apparatus which is fixed to the stem body. The insertion inlay has an insertion stocking, which is movable between an outer position, in which the insertion inlay is at least partially located outside of the stem body, and an inner position, in which the insertion stocking covers the stem body.

A system for supporting a liner on a frame element includes a liner and a frame element. A fastener connects the liner to the frame element, such that the fastener corresponds to an aperture defined by the frame element. The fastener is configured and dimensioned to removably secure to the frame element at the at least one aperture. The frame element comprises a semi-rigid or rigid base frame element, and an interface layer secured about the base frame element. The interface layer is formed from a resilient material more compressible than the base frame element, and the liner is more flexible than the interface layer.

A prosthetic suspension-mounting system which employs an improved flathead bolt and socket centering cup combination for securement of an-amputee-limb enveloping liner within a prosthesis. The liner has a strap fixedly attached on the bottom end of the liner by a flathead bolt. The mounting system also includes a containment socket for seating the liner in the prosthesis using the head of the flathead bolt as a bearing surface against a floor of the socket. The containment socket has a slot there through at a position corresponding to the strap of the liner. The socket is provided with a disk-shaped recess having a flat floor, and the liner is provided with a distal flathead bolt having a flat head to provide a direct bearing surface against the floor of the socket. This provides a delimited bearing surface to keep the liner substantially centered within the prosthesis while still affording a lateral degree of freedom to avoid concentration of lateral forces.

A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension. An attachment pin extends from a distal end of the prosthetic liner. A connector assembly secures to a distal end of the prosthetic socket and is adapted for receiving and locking to the attachment pin. A lanyard assembly has a first end secured to the connector assembly and a second end extending outwardly from the distal end of the prosthetic socket and adapted to secure to an exterior surface of the prosthetic socket by an external securing system.
