  • Patent number: 7846115
    Abstract: A motion controlling hinge for an orthopedic brace is provided. The hinge includes an actuator secured to one arm, and at least one spring member. As the arm with the actuator pivots in a first direction, at a predetermined flexion angle the actuator applies a force to the spring member, causing the spring member to flex. The spring member exerts a force on the actuator tending to bias the actuator away from the spring member, and tending to bias the arm in a second direction opposite the first direction. A movable fulcrum enables adjustment of a force exerted by the spring member on the actuator. A variety of differently sized adapters are securable to the actuator. The size of the adapter determines the flexion angle at which the spring member first exerts force on the actuator.

As the arm with the actuator pivots in a first direction, at a predetermined flexion angle the actuator applies a force to the spring member, causing the spring member to flex. The spring member exerts a force on the actuator tending to bias the actuator away from the spring member, and tending to bias the arm in a second direction opposite the first direction. In one embodiment, the spring member comprises a plurality of flat bar leaf springs. A movable fulcrum enables adjustment of a force exerted by the spring member on the actuator. A variety of differently sized adapters are securable to the actuator. The size of the adapter determines the flexion angle at which the spring member first exerts force on the actuator. In some embodiments, the hinge includes an “ON”/“OFF” switch that enables a user to disengage biasing force provided by the spring member.

  • Patent number: 7749181
    Abstract: A patellofemoral brace including a buttress for supporting a wearer's patella is provided. The patellofemoral brace includes an elastic sleeve that is easy to apply to the wearer's leg and easy to remove from the wearer's leg. The sleeve includes distinct bands of material so that end bands are substantially rotationally independent of a central band. The end bands resist translation along and rotation about the wearer's leg. The brace further includes a tensioning strap that lies across the buttress to further support the buttress and the wearer's patella. A portion of the tensioning strap is constructed of a thermoplastic elastomer, so that the strap provides firmer support to the buttress than a fabric strap, but is more comfortable and more evenly supports the buttress than a hard, inelastic strap.

  • Patent number: 7722555
    Abstract: A lockable hinge for use in orthopedic braces is provided. When used in a knee brace, the present hinge provides a knee-immobilizing brace that assists persons with standing and/or walking. The hinge is easily converted from a locked mode to a free range of motion mode and vice versa. When the hinge is in the locked mode, patients are better able to stand and walk. With the push of a button, the patient can bend his or her knee to sit or lie down more comfortably. When the hinge is in the free range of motion mode, patients are better able to participate in physical therapy activities without the hinge locking.

  • Patent number: 7658720
    Abstract: An orthopedic appliance such as a body brace or a prosthesis includes a substantially rigid structure adapted to be placed against a body portion. The orthopedic appliance of the invention includes a moisture management system for facilitating the removal of moisture that would otherwise accumulate between the affected body portion and the substantially rigid structure. The moisture management system includes a plurality of ventilation holes through the substantially rigid structure, and means for facilitating the transfer of moisture directly out through the ventilation holes to the atmosphere. The facilitating means can include a flexible support means disposed between the substantially rigid body portion, the support means either being porous, or the support means having a plurality of holes therethrough in alignment with the holes in the substantially rigid structure.

  • Patent number: 7648472
    Abstract: The pneumatic Achilles sleeve assembly comprises a sleeve and at least one strap for fastening the sleeve around the ankle. The sleeve assembly positions an arch cell which contains a dynamic volume of air within the sleeve under a human foot. The arch cell is fabricated from a flexible material and is in communication with a conduit member. Upon application of external pressure to the arch cell, air is expelled from said air cell through said conduit member. The sleeve assembly also positions a tendon cell which contains a dynamic volume of air within the sleeve against the Achilles tendon. The tendon cell is in communication with the arch cell via the conduit member. The tendon cell is also fabricated from a flexible material. Upon the expelling of air from said arch cell, the air enters through the conduit member into the tendon cell which exerts a greater pressure against the Achilles tendon.

  • Publication number: 20100010409
    Abstract: A knee brace assembly is provided having an adjustable, pressure-applying gear system mounted to a portion of the hinge assembly. Through selective adjustment of the gear system, the knee brace assembly can apply pressure to a portion or portions of the knee joint, thereby relieving pressure on the knee joint. A method of treating a knee joint using a knee brace assembly including a planetary gear system is also provided.

  • Patent number: 7563236
    Abstract: A shoulder sling is provided for the treatment of, for example, gleno-humeral dislocations and subluxations, capsular shifts, postoperative rotator cuff repair, postoperative Bankart procedures and soft tissue strains and repairs. The sling includes a support pillow abuts the wearer's torso, and a pouch that receives the wearer's arm. A plurality of straps suspend the pillow and pouch from the wearer's non-treatment shoulder. One of the straps prevents the pillow from shifting relative to the user, thus securely maintaining the wearer's arm at desired angles of abduction and external rotation. The pillow further includes an attached exercise grip and an indicator line that aids a physician in properly fitting the sling to the wearer.
