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

Publication number: 20190117414Abstract: Various features for improving the performance of prosthetic sport feet are provided. A fairing for a prosthetic sport foot can include foam components that are coupled to the foot and an elastane cover. The fairing is configured to alter the cross-sectional profile of the foot to produce a more aerodynamic shape. A prosthetic sport foot can include a hollow foot member that can be lighter weight and provide improved performance. A prosthetic sport foot can include an adjustable tension strap extending between and coupled to two portions of the foot member. A prosthetic sport foot, such as a prosthetic running foot or prosthetic cycling foot, can include an aerodynamic fairing and a cover. A prosthetic sport foot can have a varying-width profile such that a mid-section of the foot is narrower and a toe portion flares outward.Type: ApplicationFiled: October 18, 2018Publication date: April 25, 2019Inventors: Arinbjörn Viggo Clausen, Christophe Lecomte, Dana Stewart Marlin, Lárus Gunnsteinsson

Patent number: 10010434Abstract: A prosthetic or orthotic device includes a body configured to support at least a portion of a human limb of a user wearing the prosthetic or orthotic device. The device can also include a shock absorption member coupled to the body. The shock absorption member includes one or more magnetorheological elastomer (MRE) springs disposed between a first portion of the body and a second portion of the body. The one or more MRE springs are selectively actuatable to vary a stiffness of the shock absorption member via the application of a magnetic flux, thereby adjusting a stiffness of the body of the prosthetic or orthotic device to a level corresponding to an activity level of the user.Type: GrantFiled: July 28, 2017Date of Patent: July 3, 2018Assignee: Össur Iceland ehfInventors: Freygardur Thorsteinsson, Ivar Gudmundsson, Christophe Lecomte

Patent number: 9737420Abstract: An alignment adapter for prosthetic sport feet, such as running feet, includes a male pyramid plate having a male pyramid, a female connector plate having a female connector, and a back plate. For use during alignment of a prosthetic running foot, the male pyramid plate is coupled to the back of a user's socket and the female connector plate and back plate are clamped about the foot. The male pyramid and female connector are coupled and adjusted relative to one another to achieve a desired alignment. The socket and foot are locked in an alignment fixture to maintain the alignment and the male pyramid, female connector, and back plates are removed. A laminated plate is coupled to the socket to maintain alignment during normal use.Type: GrantFiled: December 22, 2015Date of Patent: August 22, 2017Assignee: Ossur hfInventors: Francois Van der Watt, Christophe Lecomte
