A prosthesis foot is provided with a structural component with proximal connecting device for fixing the prosthesis foot to a lower leg tube, lower leg shaft or a prosthesis knee joint, wherein the proximal connecting device is designed as a joint or comprises as at least one joint.

A transtibial prosthetic device comprises a pylon configured as a unitary truss structure formed of a plurality of elongated supports interconnected at nodes and having open spaces between supports of the plurality of elongated supports. The unitary truss structure comprises a polymer. A foot-ankle complex extends from a base of the pylon. The foot-ankle complex comprises an s-shaped posterior portion, an s-shaped anterior portion, and a sole portion. The s-shaped posterior portion and the s-shaped anterior portion both extend from the sole portion, have upper portions with curvatures that are concentric with each other, and are separated from each other by a gap.

A hollow tubulous composite structure and method for prosthetic limbs is described.

A load bearing assistance apparatus for transferring load from a lower extremity orthotic or prosthetic device to the ground. The load bearing assistance apparatus includes a lateral and a medial spring-loaded members and a linking mechanism for connecting the load bearing assistance apparatus to the lower extremity orthotic or prosthetic device. The linking mechanism also connects the lateral and medial spring-loaded members in a spaced apart configuration so as to position them adjacent the lateral and medial portions, respectively, of the foot of the user of the lower extremity orthotic or prosthetic device and such that a portion of the lateral and medial spring-loaded members enters in contact with the ground during locomotion.

A hollow tubulous composite structure and method for prosthetic limbs is described.

A prosthetic foot may comprise a resilient lower member, a resilient upper member and an upper bracket. The resilient lower member may comprise a front end, a middle, and a rear end. The resilient upper member may comprise a front end and a rear end. The rear end of the upper member is coupled to the rear end of the resilient lower member and the resilient upper member is positioned over the resilient lower member. The mounting bracket may comprise a front end and a rear end. The front end is coupled to the front end of the resilient upper member and the rear end is configured to attach to the residual limb of the user. The resilient lower member and resilient upper member of the prosthetic foot fit completely within a foot shell.

A stable shock absorbing prosthetic foot that transfers energy between heel strike and toe-off. A toe plate is separated from one or more other plates by a bumper assembly located at each of the toe end and heel end of the foot. Certain embodiments of the shock absorbing foot of the present invention are designed for use with a prosthetic ankle. A torsion adapter may also be used to attach a prosthetic foot of the present invention to the remainder of a prosthesis.

A lower limb prosthetic device (10) adapted to be connected to an attachment section such as a sleeve, configured to attach to the limb, or a socket to receive the limb, of an amputee, wherein the prosthetic device (10) comprises (a) a leaf spring member (12), said upper leaf spring member (12) having a proximal, upper, end (14), which proximal end (14) can be fixedly and/or adjustably attached to the attachment section, the leaf spring (12) member further comprising a distal, lower, end (16), which distal end (16) can be fixedly and/or adjustably attached to a foot member (30).
