A prosthesis socket retaining device and a system for securing a prosthesis socket to an upper extremity, comprising a securing part that can be guided along the torso below the axilla of the contralateral, unprovided side of a patient, and a coupling element which can be secured to the prosthesis socket and connected to the securing part, wherein the coupling element is displaceably mounted on the securing part.

A prosthetic cover for a prosthetic support element can include a substantially cylindrical hollow body with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal and a second flexible end seal can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

A suspension interface having a fabric layer with an open proximal end and a closed distal end. The fabric layer can be knit or woven and is preferably made from a stretchable, breathable material such as nylon. At a pre-determined point along the length of the fabric layer, an external sealing element is affixed using conventional gluing means creating a bond layer. The suspension interface has an internal grip layer or external grip layer that is preferably silicone but may also be a thermoplastic material such as urethane. The internal or external grip layer can be as thick as one inch in thickness and as thin as 1/64 of an inch but is preferably about ⅛ of an inch.

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.

The present disclosure relates to a tube-shaped cover for covering an amputation stump, wherein the cover has at least one open end for introduction of said amputation stump, wherein the cover comprises an elastic textile material in the shape of a tube; a friction increasing material arranged to be in contact with the amputation stump; and a moisture absorbing and/or moisture transferring material, preferably wherein the moisture absorbing and/or moisture transferring material is a moisture absorbing material. The present disclosure also relates to a kit comprising a cover according to the present disclosure and a sleeve configured to create a seal between an upper edge of a prosthetic socket and an amputation stump covered by said cover.

The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall, wherein between the first housing and the second housing, there is an air gap. The distal end adapted for linking an interconnecting adapter of the socket, the first housing and the second housing are made of single 3D printed part, wherein the first housing comprises an elastic region comprising set of shaped openings, and the first housing is connected with the second housing through a reinforcing structure composed of ribs.

A seal (24) for a suspension liner (30) comprises a tubular substrate having an axis and a plurality of fins (26) projecting radially from the substrate. The tubular substrate has an axis and the fins (26) nm reciprocate axially as they nm peripherally around the substrate. The seal (26) may be mounted on the suspension (30) liner or fins may be integrally formed on the outer surface of the liner.

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.

A prosthetic cover (104) for a prosthetic support element (102) can include a substantially cylindrical hollow body (106) with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal (108) and a second flexible end seal (110) can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

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.
