  • Patent number: 10064749
    Abstract: An orthopedic device includes a posterior shell with ankle and foot receiving portions. The foot receiving portion defines a plantar shell portion and side shell portions extending along first and second sides of the plantar shell portion and forming an open-ended toe portion. A toe protector portion is removably attached to the posterior shell at the open-ended toe portion and arranged to protect the toes of the user. The toe protector portion extends between the side shell portions and longitudinally along a length of the side shell portions. At least one inflatable bladder is disposed in at least the ankle receiving portions and at least one pump assembly is in fluid communication with the at least one inflatable bladder.

  • Patent number: 9492301
    Abstract: 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.

  • Patent number: 9468553
    Abstract: An orthopedic device includes a posterior shell with ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect of the posterior shell. A dorsal shell is contoured to substantially correspond to the opening of the posterior shell. The dorsal shell includes a proximal member and a distal member hingedly connected to the proximal member via a hinge mechanism. A pump assembly receiving opening is defined in the proximal member of the dorsal shell and a raised portion extends longitudinally along an exterior surface of the dorsal shell. A plurality of clearance holes are defined in the first and second wing portions. An inflatable bladder is disposed at least in the ankle receiving portion of the posterior shell. A pump assembly is inserted through the pump assembly receiving opening and is in fluid communication with the inflatable bladder.
