Patent number: 9999524Abstract: 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: GrantFiled: June 30, 2015Date of Patent: June 19, 2018Assignee: Össur hfInventors: Arinbjörn Viggo Clausen, Ragnar Örn Gunnarsson, Bjarni Andresson, Lárus Gunnsteinsson, Rowan Patrick Robinson Cain

Publication number: 20180153759Abstract: Various features for improving the performance of crutches are provided. A crutch can flex at one or more locations or include composite material to provide energy storage and return to the user during ambulation. In some aspects, a crutch is provided that can propel the user forward during ambulation. The crutch can be hollow at one or more locations to allow for increased flexibility and narrower at one or more locations to enhance springiness of the crutch.Type: ApplicationFiled: May 31, 2017Publication date: June 7, 2018Inventors: Arinbjörn Viggo Clausen, Aron Kristbjorn Albertsson, Gudfinna Halldorsdottir

Patent number: 9949850Abstract: A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.Type: GrantFiled: September 16, 2016Date of Patent: April 24, 2018Assignee: Össur Iceland ehfInventor: Arinbjörn Viggo Clausen

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

Patent number: 9462966Abstract: Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual.Type: GrantFiled: October 23, 2014Date of Patent: October 11, 2016Assignee: Össur hfInventors: Arinbjörn Viggo Clausen, Magnús Oddsson

Patent number: 9427338Abstract: A prosthetic foot can include a plate-like foot member extending along a longitudinal axis between an anterior end generally corresponding to a toe portion of a foot to a posterior end, and a metatarsal hinge comprising an elongate groove extending between medial and lateral edges of the foot member. The elongate groove can intersect the longitudinal axis of the foot member, and can be positioned along the length of the foot member at a location generally corresponding to a metatarsal region of the foot. The metatarsal hinge can also comprise a plurality of elongate apertures that extend completely through the foot member, or a plurality of recessed channels that extend only partially through the foot member, or a combination thereof.Type: GrantFiled: October 30, 2013Date of Patent: August 30, 2016Assignee: Össur hfInventors: Arinbjörn Viggo Clausen, Lárus Gunnsteinsson

Patent number: 9351854Abstract: 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. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. 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.Type: GrantFiled: April 28, 2014Date of Patent: May 31, 2016Assignee: Össur hfInventors: Helgi Jónsson, Arinbjörn Viggo Clausen, Gudni Ingimarsson, Christophe Lecomte, Larus Sigfusson, Heidrún Gígja Ragnarsdöttir

Publication number: 20150265429Abstract: Control systems and methods are disclosed for processing a time series of signals associated with the movement of a device associated with a limb. The time series of motion signals is filtered, such as thorough an autoregressive filter, and compared to stored data sets representing a limb-motion event and/or phase. In certain examples, a plurality of accelerometers generate the time series of motion signals based at least on acceleration measurements in three orthogonal directions and/or planes. The acceleration measurements may relate to the movement of an artificial limb, such as a prosthetic or orthotic device. Upon determining an event and/or phase of limb motion, the control system may trigger an actuator to appropriately adjust one or more prosthetic or orthotic joints.Type: ApplicationFiled: June 8, 2015Publication date: September 24, 2015Inventors: Helgi Jónsson, Arinbjörn Viggo Clausen, Heidrun G.

Publication number: 20150209160Abstract: 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: January 29, 2015Publication date: July 30, 2015Inventors: Arinbjörn Viggo Clausen, Christophe Lecomte, Dana Stewart Marlin, Lárus Gunnsteinsson
