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.

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 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.

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 connector apparatus for securing a liner disposed around a residual limb of a user to a distal prosthetic member is provided. The apparatus includes a body member having a roller rotatably mounted to a side wall in a slot in the body member, a socket disposed around the body member and having an opening aligned with the slot of the body member, and a strap having a first end coupled to the liner. The socket facilitates attachment of the distal prosthetic member to the body member. The strap extends through the slot in the body member against the first roller and through the opening in the socket. The strap continues to extend along an exterior surface of the socket and is attached to itself, thereby securing the liner to the distal prosthetic member.
