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: 7611543Abstract: A prosthetic foot (124) incorporates a foot keel (165) and a calf shank (126) connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and an upwardly arched midfoot portion extending between the forefoot and midfoot portions. The calf shank includes an anterior facing convexly curved lower portion which is adjustably attached at a portion thereof to the foot keel by way of a releasable fastener arrangement. The upper end of the calf shank is movable longitudinally of the foot keel in response to force loading and unloading the calf shank during use of the prosthetic foot. A device (125) connected between the upper end of the calf shank and the lower portion of the prosthesis can be used to assist posterior movement of the upper end of the calf shank and control anterior movement of the upper end of the calf shank during use of the prosthesis.Type: GrantFiled: April 1, 2004Date of Patent: November 3, 2009Assignee: Bioquest Prosthetics, LLCInventors: Barry W.

Patent number: 7371262Abstract: In one embodiment, an impact and torque-absorbing module for a low profile lower limb prosthesis comprises two support members telescopingly engaged to permit axial and rotational motion therebetween. A resilient element resists axial displacement of the two support members, and a torque resisting cuff resists rotational displacement of the two support members. Precompression of the resilient element can reduce the size of the shock module making it more compact. The resilient element can also be replaced allowing adjustment of the shock absorption.Type: GrantFiled: September 2, 2005Date of Patent: May 13, 2008Assignee: Össur hfInventors: Christophe Guy Lecomte, Heidrun Gigja Ragnarsdottir

Patent number: 7364593Abstract: A prosthetic foot incorporate a foot keel and a calf shank connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and a relatively long midfoot portion extending between and upwardly arched from the forefoot and midfoot portions. The calf shank includes a downward convexly curved lower end which is attached at a portion thereof to the keel midfoot portion by way of an adjustable fastener arrangement. The foot has biplanar motion capability and, in a preferred form, also has high low dynamic response characteristics. The adjustable fastener arrangement permits adjustment of the alignment of the calf shank and the foot keel with respect to one another in the longitudinal direction of the foot keel for tuning the performance of the prosthetic foot.Type: GrantFiled: April 8, 2003Date of Patent: April 29, 2008Assignee: Bioquest Prosthetics LLCInventors: Barry W.

Patent number: 7112227Abstract: A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. In one embodiment, a prosthetic foot connection component is connected to a prosthetic lower leg connection component only by means of an elastomeric material, thereby allowing for multi-axis movement of the ankle without requiring direct contact between the two components. In other embodiments of the ankle, a prosthetic foot connection component may be mechanically connected to a prosthetic lower leg connection component. However, the design of the mechanical connection and the use of an elastomeric material casing allows for movement of the ankle without surface-to-surface sliding contact between the two components. Compression of the elastomeric material, as well as one or more mechanical stops may be used to control and limit movement of the ankle.Type: GrantFiled: February 3, 2004Date of Patent: September 26, 2006Assignee: The Ohio Willow Wood CompanyInventors: Jeffrey L.

Patent number: 7108723Abstract: A prosthesis is disclosed for improving the gait and comfort qualities of the amputee that participates in walking, running and jumping activities. A foot and an ankle of the prosthesis are monolithically formed as a resilient member including a strut which forms an ankle joint. A hole extends through the resilient member with the periphery of the hole forming an anterior side surface of the strut. The resilient member anterior to the hole includes a gap to permit motion about the ankle joint axis while providing a stop in dorsiflexion. The hole is elongated upwardly such that the strut is upstanding and anterior convexly curved.Type: GrantFiled: June 10, 2004Date of Patent: September 19, 2006Inventors: Barry W. Townsend, Byron K.

Patent number: 7060104Abstract: A prosthetic foot characterized by an easily exchangeable auxiliary ankle member demountably attached to forefoot and sole portions, which are in turn demountably and interchangeably connected. The forefoot, heel and auxiliary ankle portions are fabricated from polymer impregnated and encapsulated laminates, including such laminates as carbon fibers and/or fiberglass or synthetic fibers such as Kevlar. The easily demountable connection of the auxiliary ankle permits interchangeability thereof to match the activity schedule of the wearer utilizing the prosthetic foot without the necessity of frequent visits to the prosthetist. A compressible member between the forefoot member and the sole member, and function blocks located between the various members provide additional adjustability. The orientation of the auxiliary ankle member and compressible member also allows for increased plantar flexion.Type: GrantFiled: April 9, 2003Date of Patent: June 13, 2006Inventor: Van L. Phillips

Patent number: 6936074Abstract: A prosthetic foot is disclosed for improving the gait and comfort qualities of the amputee that participates in walking, running and jumping activities. An ankle pylon component attached to a foot keel of the foot allows hindfoot triplanar motion. An ankle joint and a subtalar joint provided in the hindfoot ankle pylon component permit closed kinetic chain motion of the foot. The ankle and subtalar joints are formed by respective struts of resilient material of a single piece of material of the ankle pylon component. The ankle pylon component can be used as a functional upgrade component to an existing low profile prosthetic foot, for example.Type: GrantFiled: March 2, 2004Date of Patent: August 30, 2005Inventors: Barry W.

Patent number: 6899737Abstract: A simple, inexpensive prosthetic foot is provided incorporating a cushioned ankle including an ankle block formed of a resilient material or bladder having desired compliance and energy return characteristics. The ankle block is sandwiched between a foot element and an ankle element. One or more openings extends through the ankle block with a substantially transverse orientation relative to a forward walking motion. The size and shape of these openings, as well as the insertion of different types of stiffeners therein, provide desired performance characteristics to the ankle block. When the ankle block takes the form of one or more inflatable bladders, the pressure within these bladders is individually controlled by valves to provide desired performance characteristics to different portions of the prosthetic foot. A pump system can also be used to control and generate fluid pressure into these bladders.Type: GrantFiled: October 26, 2000Date of Patent: May 31, 2005Inventors: Van L. Phillips, Hillary Pouchak
