Patent number: 11793657Abstract: A prosthetic socket system includes a prosthetic lock assembly having a lock body defining a pin hole adapted to receive an attachment pin, and a locking device in the lock body. The locking device is engageable with the attachment pin to unidirectionally lock the attachment pin in the lock body while permitting insertion of the attachment pin in the lock body. A valve assembly is positioned in the lock body that is movable between a closed position and an open position in which the valve assembly is unsealed so that air moves into the lock body via the valve assembly. A release mechanism positioned in the lock body is arranged to both release the locking device from the attachment pin and move the valve assembly to the open position by translating the locking device in the lock body.Type: GrantFiled: November 1, 2018Date of Patent: October 24, 2023Assignee: OSSUR ICELAND EHFInventors: Stefan Krämer, Christof Kurth, Hogna Hringsdottir, Linda Ros Birgisdottir

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: 20230042794Abstract: An adjustable seal system includes a seal component having a body having an outer surface defining a socket sealing portion arranged to engage and form an airtight seal with an interior surface of a prosthetic socket. The inner surface of the body defines a liner sealing portion arranged to frictionally engage and seal with an outer surface of a prosthetic liner. The liner sealing portion defines a sealing length extending in a proximal direction from an end of the socket sealing portion and terminating at a proximal edge on the body. The length of the liner sealing portion is between about 25 mm and about 35 mm and is selected in relation to the socket sealing portion to vary tractions at the inner and outer surfaces of the seal component.Type: ApplicationFiled: October 20, 2022Publication date: February 9, 2023Inventors: Linda Ros BIRGISDOTTIR, Martin Lund STORUP, Hogna HRINGSDOTTIR, Rowan CAIN

Publication number: 20210161686Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.Type: ApplicationFiled: February 4, 2021Publication date: June 3, 2021Inventors: Andrew BACHE, Egill Sveinbjorn EGILSSON, Linda Ros BIRGISDOTTIR, Dana Stewart MARLIN
