Publication number: 20240108482Abstract: 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.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Andri ORRASON, Stefan Orn STEFANSSON, Rowan CAIN, Sigurdur ASGEIRSSON, Jiri DLAB

Publication number: 20240009009Abstract: An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the socket system to the closed configuration.Type: ApplicationFiled: September 26, 2023Publication date: January 11, 2024Inventors: Andrew BACHE, Martin Lund STORUP, Alexander JOHONNUSON, Andri ORRASON, Gudmudur KARASON

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

Publication number: 20220314540Abstract: 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.Type: ApplicationFiled: June 22, 2022Publication date: October 6, 2022Inventors: Sigurdur ASGEIRSSON, Jiri DLAB, Larus SIGFUSSON, Rowan CAIN, Stefan Orn STEFANSSON, Andri ORRASON, Linda Ros BIRGISDOTTIR, Hogna HRINGSDOTTIR

Publication number: 20220192848Abstract: 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.Type: ApplicationFiled: March 14, 2022Publication date: June 23, 2022Inventors: Martin Lund STØRUP, Rowan CAIN, Linda Ros BIRGISDOTTIR, Hogna HRINGSDOTTIR, Sigurdur ASGEIRSSON, Stefan Orn STEFANSSON, Andri ORRASON
