Publication number: 20240041621Abstract: Prosthetic feet that allow for heel height adjustment and/or provide metatarsal joint functionality to more closely mimic natural human feet are provided. A prosthetic foot can include an ankle module having a locking mechanism configured to lock the heel at a particular height. The prosthetic foot can also include a toe region that adapts to varying heel heights. The ankle module and/or locking mechanism can be adjusted, controlled, and/or locked via a hydraulic mechanism. The toe region can curve upward relative to a portion of the foot proximal of the toe region.Type: ApplicationFiled: August 22, 2023Publication date: February 8, 2024Inventors: Aron Kristbjorn Albertsson, Maria Gudrun Sveinbjornsdottir, Rowan Patrick Robinson Cain, Jeroen Nijman, David Sandahl, Larus Gunnsteinsson

Publication number: 20240000597Abstract: A hinge has a hinge body forming an articulating section extending between a first end and a second end of the hinge. The articulating section is adapted to bend from a neutral axis when the first and second ends are parallel to an angular range in which the first end is arranged among a plurality of angles within the angular range relative to the second end. The hinge body may define a receptacle along the articulating section, and an insert may be provided for insertion into the receptacle. The insert can modify the stiffness of the hinge in the angular range and is arranged parallel to the neutral axis.Type: ApplicationFiled: September 12, 2023Publication date: January 4, 2024Inventors: Larus GUNNSTEINSSON, Bjorn OMARSSON, Sindri Pall SIGURDSSON, Henry HSU

Publication number: 20230293319Abstract: A foot cover for a prosthetic foot can allow a user to more easily remove the foot cover when the foot cover needs to be switched out or cleaned. The foot cover can have a hinge near a heel end of the foot cover. The hinge can allow a user to rotate a section of the foot cover to increase the size of the opening so that the foot prosthetic can be inserted into or removed from an inner cavity of the foot cover. The foot cover can be an easily separable two-part foot cover, the two parts coupled together with magnets or another mechanical fastener.Type: ApplicationFiled: March 8, 2023Publication date: September 21, 2023Inventors: Bjarni Andresson, Larus Gunnsteinsson, Jeroen Nijman, Felix Starker, Aron Kristbjorn Albertsson, Maria Gudrun Sveinbjornsdottir

Publication number: 20220151812Abstract: An orthopedic walker includes a body formed from at least one polymeric material and having a unitary construction. The body forms first and second portions divided by a median plane and connected to one another by a footbed. The first and second portions extend from the footbed and form an interior volume for receiving a foot and lower leg of a user. The first and second portions are arranged to articulate about or from the median plane to expand and retract the interior volume. The body consists of the first and second portions, and the footbed inclusive of an outsole having a tread as a continuous structure formed unitarily from the at least one polymeric material. The at least one polymeric material is an expanded thermoplastic.Type: ApplicationFiled: November 17, 2021Publication date: May 19, 2022Inventors: Larus GUNNSTEINSSON, Sindri Pall SIGURDSSON, Jane PRICE, Asdis BJORNSSON, Matthew BARRIENTOS

Publication number: 20220125607Abstract: A vacuum suspension system includes a foot cover having a heel portion and a pump system located in the heel portion. The pump system includes upper and lower sections arranged to move in an axial direction relative to one another and a pump mechanism operatively connected to and positioned between the upper and lower sections. When the heel portion is loaded in stance the pump mechanism moves from an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, to an expanded configuration in which the volume of the fluid chamber is increased.Type: ApplicationFiled: January 11, 2022Publication date: April 28, 2022Inventors: Atli Orn SVERRISSON, Larus GUNNSTEINSSON, Gudfinna HALLDORSDOTTIR, Hafsteinn JONASSON, Dadi GRANZ, Dana Stewart MARLIN

Publication number: 20220079781Abstract: Prosthetic feet and foot covers that provide a more natural appearance and improved performance are provided. A foot element for a prosthetic foot can extend from a heel end to a toe end and include a heel, arch, forefoot, and toe regions. The forefoot region can be wider than the arch and heel regions. The toe region can include a U-shaped cut out to define a big toe. Various features of the foot element can guide rollover of the foot through the big toe during use. A foot cover can be designed to receive a prosthetic foot including such a foot element. The foot cover can have a region of increased flexibility at a transition between the forefoot region and toe region. The foot cover can also have a padded area extending from the heel region across a lateral part of the arch region and forefoot region.Type: ApplicationFiled: September 24, 2021Publication date: March 17, 2022Inventors: Arinbjorn Viggo Clausen, Ragnar Örn Gunnarsson, Bjarni Andresson, Larus Gunnsteinsson, Rowan Patrick Robinson Cain
