  • Flexion enhancement member for prosthetic or orthotic liner or sleeve and associated methods
    Patent number: 9066820
    Abstract: The liner or sleeve is for use around a joint, for example, as a skin interface between a limb and a prosthetic or orthotic device. The liner or sleeve includes an elastomeric material defining a tubular member to be positioned around a joint. A tendon is attached along a portion of the tubular member to urge the elastomeric material at such portion of the tubular member to contract. The tendon may be integrally molded within the portion of the tubular member. The tendon may be formed of an elastomeric material having a higher durometer hardness relative to the durometer hardness of the tubular member elastomeric material. With the present approach, it is possible to maintain the use of a two part mold while providing a liner or sleeve with enhanced flexion adjacent to a joint area.
