    摘要： A prosthetic foot comprising a vacuum system configured to attach to a vacuum attachment apparatus and a residual limb. The prosthetic foot may comprise a resilient bottom member, a resilient top member, and a vacuum system. The resilient bottom member may comprise a front end and a rear end. The resilient top member may comprise a front end and a rear end and the front end of the resilient top member may be connected to the front end of the resilient bottom member. The vacuum system may be coupled to an underside of the rear end of the top member. The vacuum system may comprise a compressible member, a chamber located within the compressible member, a universal valve system received within the compressible member, a passageway connecting the valve system and the chamber, and an air return coupled to the valve system and the vacuum attachment apparatus.

    摘要： Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

    摘要： Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.

    摘要： An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.
