Patent number: 9668887Abstract: The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element.Type: GrantFiled: September 14, 2015Date of Patent: June 6, 2017Assignee: Össur hfInventors: Christophe Guy Lecomte, Hjordis Thorhallsdottir, Heidrun Gígja Ragnarsdottir, Arinbjörn Viggo Clausen

Publication number: 20150164661Abstract: A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface. For example, the processing module may receive a heel height input from the user.Type: ApplicationFiled: December 17, 2014Publication date: June 18, 2015Inventors: Heidrun Gigja Ragnarsdottir, Arinbjörn Viggo Clausen, Hjordis Thorhallsdottir, Helgi Jónsson

Publication number: 20120165958Abstract: A cover for a foot prosthesis comprises an opening at a top end of the cover, which extends into a cavity formed within the cover, wherein the cavity is configured to receive a prosthesis therein. A wall surrounds the cavity and has the shape of a natural human foot. The wall has an inner surface and an outer surface. The wall also has a top section, a bottom section and a rear section. The bottom section defines a sole area having a toe section, a heel section, and a metatarsal region, wherein the sole area is provided with varying levels of stiffness configured to induce a desired rollover from heel-to-toe in a lateral-to-medial direction.Type: ApplicationFiled: March 1, 2012Publication date: June 28, 2012Applicant: Ossur hfInventors: Arinbjörn Viggo Clausen, Erla Sigridur Gestsdottir, Christophe Lecomte, Heidrun Gigja Ragnarsdottir, Hjordis Thorhallsdottir
