  • Publication number: 20240108482
    Abstract: A prosthetic liner has a ventilated structure communicating with an interior volume to an exterior of the prosthetic liner, thereby permitting a transfer of air and moisture therebetween. The prosthetic liner includes a facing layer defining a periphery of at least part of the interior volume of the liner, and forming a plurality of apertures extending therethrough. A cushion layer is juxtaposed to the facing layer and forms a lattice structure including a plurality of interstices in communication with the apertures of the facing layer.

  • Publication number: 20230320875
    Abstract: A method for making a prosthetic liner includes the steps of providing a textile sleeve, applying an uncured silicone material onto an inner surface of the textile sleeve and impregnating interstices of a high-density knit structure of the textile sleeve. The silicone material is a fast-cure silicone material arranged to reach at least 90% cross-linking faster than conventional silicone material. The silicone material is preferably limited to the inner surface of the textile sleeve, whereas the outer surface is devoid of the silicone material. The silicone defines an inner layer forming the interior surface of the liner, and the outer surface of the textile sleeve forms the exterior surface of the liner. A thickness of the liner from the interior surface of the liner to the inner surface of textile layer consists of the silicone of the inner layer.

  • Publication number: 20230115195
    Abstract: An additive manufacturing system and method for making components having filaments formed by elastomeric materials. A liner includes the filaments formed by an elastomeric material and is adapted for a prosthetic device system. The filaments form an elastomeric lattice structure and solid layers or features and define a ventilated structure permitting a transfer of air and moisture from an interior volume of the liner to an exterior or ambient liner. The liner may incorporate an adhesive and a textile layer secured to the elastomeric lattice structure and further define recesses and other features for improving a liner.

  • Patent number: 11523917
    Abstract: A suspension liner has a liner body portion, a textile material, and a plurality of seals formed along a length of the suspension liner toward a closed distal end and protruding circumferentially about a liner profile. Each seal has a same shape including a peak having a rounded profile and a width narrowing toward the peak and defines a sealing surface arranged to form a secure interface with an interior wall of the socket that retains the suspension liner within the prosthetic socket. The textile material is located intermediate interior and exterior surfaces of the suspension liner that formed of one or more silicone materials in the area of the seals and the textile material defines the exterior surface of the suspension liner proximal and distal to the seals.

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.

  • Publication number: 20220192848
    Abstract: A prosthetic interface includes a body portion having an open proximal end and a closed distal end including a distal cup. The body portion includes a membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface. At least one material coating is selectively applied to the membrane component that interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the internal flow space and the residual limb, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket.
