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: 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: 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

Patent number: 10945865Abstract: A prosthetic socket system includes a distal seal positionable between an interior surface of a prosthetic socket defining a pin bore and a distal end of a prosthetic liner carrying an attachment pin arranged to extend through the pin bore. The distal seal includes a base proximate to the attachment pin and defining an opening configured to receive and surround the attachment pin, a sealing portion extending distally from an outer radial portion of the base, and a variable clearance defined between the sealing portion and the base. The sealing portion is adapted to form a seal around the attachment pin and prevent fluid flow through the pin bore by deflecting relative to the base when the sealing portion engages the interior surface of the prosthetic socket.Type: GrantFiled: November 1, 2018Date of Patent: March 16, 2021Assignee: OSSUR ICELAND EHFInventors: Hogna Hringsdottir, Dadi Granz
