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: 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: 20230285168Abstract: A prosthetic foot can allow a user to engage in different activity levels, for example, walking and running using the same prosthetic foot. The prosthetic foot can have an elongate sole member, a first upper member, and a second pre-compressed upper member such that a distal end of the second upper member is biased toward the first upper member. A spacer between the distal ends of the first and second upper members can facilitate sliding of the distal end of the second upper member during ambulation to vary the stiffness of the foot. The spacer can also improve the lever arm length of the second upper member by maintaining a gap between the first and second upper members throughout ambulation.Type: ApplicationFiled: March 7, 2023Publication date: September 14, 2023Inventors: Aron Kristbjorn Albertsson, Felix Starker, Jeroen Nijman, Victoria Pamela Anne Clark

Patent number: 11478364Abstract: A vertical suspension system for a prosthetic foot includes a first member operatively coupleable to an amputee's residual leg. The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.Type: GrantFiled: August 3, 2020Date of Patent: October 25, 2022Assignee: Össur Iceland ehfInventors: Christophe Lecomte, Benedikt Skulason, Jeroen Nijman

Publication number: 20220273466Abstract: A prosthetic foot can allow a user to engage in different activity levels, for example, walking and running using the same prosthetic foot. The prosthetic foot can have a generally C-shaped upper foot member coupled to a heel member near a toe portion of the prosthetic foot. The heel member can extend from a toe end to a heel end. The prosthetic foot can include a resilient member that can be split into a first component and a second component. The prosthetic foot can include a heel stiffening mechanism with different configurations to adjust a heel stiffness of the prosthetic foot.Type: ApplicationFiled: February 22, 2022Publication date: September 1, 2022Inventors: Jeroen Nijman, Felix Starker, Aron Kristbjorn Albertsson

Patent number: 10342680Abstract: A prosthetic ankle module allows for translational and/or rotational movement of a prosthetic foot relative to an adapter. The ankle module can include a four-bar linkage assembly. Links of the linkage assembly can be arranged in various configurations, e.g., parallel or non-parallel and having equal or non-equal lengths, to provide different functions and benefits, e.g., dorsiflexion, plantar flexion, vertical shock absorption, inversion, eversion, and/or rotation about the sagittal axis. Other types of linkage assemblies are also possible. A prosthetic foot can further include a support spring to limit the range of motion of the adapter in use.Type: GrantFiled: June 9, 2016Date of Patent: July 9, 2019Assignee: Ossur Iceland ehfInventors: Jeroen Nijman, Christophe Lecomte
