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.

Additive manufacturing system, method and corresponding components for making elastomeric structures

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.

Medical device including a structure based on filaments

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.
