Publication number: 20120165714Abstract: An orthopedic device has a main body panel including a longitudinal length with a curved cross-section, and opposed lateral and medial sides. A posterior panel is secured to the lateral and medial sides of the main body panel, and is sized longitudinally shorter than the main body panel in a non-stretched condition. The posterior panel is secured to the main body panel in a pretensioned condition and spans the longitudinal length of the main body panel along the lateral and medial sides thereof.Type: ApplicationFiled: December 20, 2011Publication date: June 28, 2012Inventors: James FORBES, STACY WYATT, YESSENIA LOPEZ, Irving HU

Publication number: 20120078148Abstract: An orthopedic device in the form of a circumferential walker includes a first member (posterior shell) and a second member (dorsal shell) corresponding to the first member. An outsole or plantar shell portion is attached to, or formed on or with the posterior shell. A hinge mechanism is provided between the posterior and dorsal shells to allow the dorsal shell to be swung away from the posterior shell in order to accommodate an anatomical limb therein. Inflatable bladders having perspiration wicking channels and/or openings are provided within a liner for insertion between the posterior and dorsal shells. Quick-connecting buckle and retaining assemblies can be provided to allow a user to quickly don and doff the orthopedic device.Type: ApplicationFiled: November 30, 2011Publication date: March 29, 2012Inventors: Irving HU, Jane LEE

Patent number: 8002724Abstract: An orthopedic device in the form of a circumferential walker includes a first member (posterior shell) and a second member (dorsal shell) corresponding to the first member. An outsole or plantar shell portion is attached to, or formed on or with the posterior shell. An expansion joint is positioned in the posterior shell or dorsal shell to expand to accommodate larger sized lower legs. The dorsal and posterior shells may include flexible or resilient edge portions to reduce pressure points and to further accommodate users having larger sized lower legs. The dorsal shell also includes a flexible or resilient connecting portion to accommodate users having larger ankles and feet and to reduce or eliminate the formation of a pressure point along the dorsal shell. Quick-connecting buckle assemblies can be provided to allow a user to quickly don and doff the orthopedic device.Type: GrantFiled: May 15, 2009Date of Patent: August 23, 2011Assignee: OSSUR HFInventors: Irving Hu, Jane Lee

Publication number: 20110146032Abstract: A strapping system includes a flexible, textile strap having locking elements. The strap defines an attachment portion upon which a reinforcement element formed from a solid mass of polymeric material inseparably and integrally secures. The locking elements of the strap are embedded at least in part into the thickness of a reinforcement element.Type: ApplicationFiled: December 7, 2010Publication date: June 23, 2011Applicant: OSSUR hfInventors: Irving Hu, Jane Lee, Yu Lau

Patent number: 7896826Abstract: An orthopedic walker for mounting on the lower leg of a patient includes a walker base having a central area for receiving the foot of a patient and a spaced lower surface including an outer sole, and a pair of struts connected to the walker base. Each of the struts has a frame member of high strength material secured to the first end of the walker base and a supporting component integrally secured and adjacent to the frame member. The supporting component defines laterally extending side wings generally corresponding to the second end of the frame member, and is constructed from a material less rigid than the high strength material of the frame member. The supporting component has a main body and a border portion that are integrally secured and contiguous with one another. The border portion is formed from a material having a lower hardness than the material forming the main body.Type: GrantFiled: September 18, 2009Date of Patent: March 1, 2011Assignee: Ossur HFInventors: Irving Hu, Chad Leeder, Tracy Grim

Patent number: 7833181Abstract: A knee brace has push button actuatable stops, wherein the stops are biased outward into angular locking positions and inwardly directed pressure on the push buttons releases the stops and permits angular adjustment of the stops. A pair of catch plates with locking recesses facing inward, are provided, and outwardly biased locking pins engage the recesses in both catch plates. Each of the stop assemblies has an outwardly directed plate extending over the outer cover plate, and this plate is coupled to the physical stop member around the outer edge of the outer cover plate. The cover plate has angular indicia thereon, which may be viewed through windows in the outwardly extending plate portions of the stop assemblies.Type: GrantFiled: May 13, 2009Date of Patent: November 16, 2010Assignee: Ossur Americas, Inc.Inventors: David Cormier, Tracy Grim, Joseph M. Iglesias, Hugo A. Cobar, Janelle R. Batman, Irving Hu, Wendee Lee, Jacqueline Jones
