Publication number: 20230320875Abstract: 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.Type: ApplicationFiled: June 16, 2023Publication date: October 12, 2023Inventors: Christophe VALOIS, Linda Ros BIRGISDOTTIR, Sigurdur ASGEIRSSON, Stefan Orn KRISTJANSSON

Publication number: 20230115195Abstract: 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.Type: ApplicationFiled: October 7, 2022Publication date: April 13, 2023Inventors: Rowan CAIN, Stefan Teitur HALLDORSSON, Ivar OLAFSSON, Sigurdur ASGEIRSSON, Andri ORRASON, Stefan Orn STEFANSSON, Halldor EINARSSON, Hafsteinn JONASSON
