The present invention relates to a prosthesis covering (100) with a closed cross-section which comprises a first section (10), a second section (20) and a third section (30). The second section (20) is arranged in longitudinal direction between the first section (10) and the third section (20) an consists of other material than the other two sections. The second section (20) may optionally at least in a first subsection (21) be folded, doubled over, raised, lamella-like or multi-layer.

A sleeve for mounting a prosthetic unit on a limb is formed using a tripartite composite that includes a breathable woven fabric in combination with an elastic urethane middle layer and a soft perforated plastic inner layer. The middle layer can be a hyper-elastic polymer that is cured to a hemispherical shape to stretch and move while maintaining a shape memory that returns the polymer to its original shape once relieved of a stretching force. Moreover, the liner/prosthetic sleeve of the present invention's anatomical suspension works as an advantage to maintain its placement on the user's residual limb.

A liner and a method for producing a liner for a lower arm prosthesis, wherein the liner comprises a base body with a closed distal end and an open proximal end, and the method comprises the production of the base body by moulding a preform, in particular using a casting or dipping method, wherein in at least one section of the preform a first diameter of the blank is greater than a second diameter in a second direction, which extends orthogonally to the first direction.

A prosthesis socket system with a rigid outer socket which has a proximal outer socket opening for receiving an extremity stump of a wearer of the prosthesis socket system, and a flexible inner socket, which is connected to the outer socket and has a proximal inner socket opening for receiving the extremity stump, wherein at least one sealing lip is arranged on an inner side of the inner socket facing the extremity stump.

A liner to an appendage of a user includes a base member, a bracket adjustably mounted to the base member to a desired height position, and a plurality of arms pivotably mounted to the bracket. 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 bracket 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 pivot outward, thereby allowing the plurality of arms and roller balls to slide the liner around the appendage of the user.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

Linings for fitting an object to a body part, and their use, are provided. The lining may include a flexible sheet having a fluid impenetrable outer portion enclosing an internal volume and the lining may include barriers forming a number of compartments substantially secured in place within the internal volume. The barriers may be permeable to gas and/or liquid, yet may be impermeable to the conformable material and the gas and/or liquid may be supplied to or aspirated from one or more compartments within the internal volume. Aspiration of gas and/or liquid from the internal volume may limit both deformation of the conformable material and shape adjustment of the flexible sheet.

A prosthetic attachment system includes an insert arranged for connection to a prosthetic liner, and an attachment unit arranged for connection to a distal end of a prosthetic socket. The attachment unit comprises a body defining an axis and a central opening for selectively receiving the insert. The body carries a plurality of locking elements that are distributed circumferentially about the axis and radially repositionable relative to the axis. A release mechanism is slidably positioned on an outer surface of the body to move the prosthetic attachment system between a locked configuration in which the locking elements are radially repositioned to lock the insert in the central opening of the body and an unlocked configuration in which the insert is released from the central opening.

A lattice or solid structure for a medical device includes a first layer of first filaments discretely formed from at least one medical-grade silicone material. The first filaments are arranged in a predetermined pattern and may be directly adjacent to one another or spaced apart. Additional layers of filaments may be provided adjacent to the first layer, and chemically bonded thereto to form an integrated structure that is without interruption or with interstices therebetween.

A system for additive manufacturing a medical device, the system comprising a first dispensing system, a second dispensing system, a deposition apparatus, and a deposition substrate on a surface of which the deposition apparatus is configured to deposit at least one elastomeric material into a filament. The deposition apparatus receives the at least one elastomeric material from the first and second dispensing systems in proportions effecting a desired property in the medical device. The deposition apparatus may comprise heating and/or cooling elements, a sonic vibration module, and/or a pneumatic suck-back valve. The deposition substrate may have a configuration corresponding to a desired shape of the medical device and is configured to rotate and/or translate relative to the deposition apparatus. The system comprises a controller configured to control the deposition.
