US Patent:

7335177, Feb 26, 2008

Filed:

Apr 22, 2005

Appl. No.:

11/111963

Inventors:

Ronan Reynolds - Long Beach CA, US
Guillermo Gustavo Weber - Brownsville TX, US
Roger Weber - Pasadena CA, US
Samuel Landsberger - Rancho Palos Verdes CA, US

International Classification:

A61F 5/00

US Classification:

602 23, 602 27

Abstract:

An ankle-foot orthosis for aiding or enhancing a user's foot and ankle movement, wherein the orthosis comprises at least one strut member, a calf shell, a foot shell, and a plurality of segments. Gaps formed between adjacent segments, an uppermost segment and the calf shell, and a lowermost segment and the foot shell have gap widths, wherein gaps at a higher location have larger gap widths than those at a lower location. Therefore, in dorsiflexion, the gaps close in series from bottom to top, gradually increasing the orthosis stiffness, creating a progressive dorsiflexion stop, and decreasing the magnitude of loads transferred into the user. In plantar flexion, the gaps similarly decrease in series from bottom to top, gradually increasing the orthosis stiffness, creating a progressive plantar flexion stop, and decreasing the magnitude of loads transferred into the user.

US Classification:

602023000, 602026000

Abstract:

A knee orthosis comprising of at least one deflection limiter () separated by gaps () on one or more struts (), which are attached to a thigh shell () and a calf shell (). The stiffness of the brace can easily be controlled in sagittal, transverse, and coronal planes whereby a person may obtain improved gait.
