Abstract: A prosthetic lower leg uses one or more generally C-shaped spring elements between the patient's socket and a footplate assembly. The respective connections between (a) those one or more elements and (b) that socket and that footplate can be configured to provide a lightweight and economic prosthesis that effectively mimics the feel and performance of a normal human foot. The prosthetic spring element is generally C-shaped, and can have a substantially constant thickness along its length, lending itself to being fabricated by automated processes such as filament winding. One or more of the generally C-shaped spring elements can be incorporated into other prostheses and/or other devices.

Abstract: A limb support device includes a variable stiffness mechanism. The limb support device can be an orthotic or prosthetic device. The variable stiffness mechanism can include, for example, a rate-sensitive or speed-dependent material or a damping mechanism. The variable stiffness mechanism causes the limb support device to exhibit different properties when the user of the limb support device is walking at high or fast walking speeds compared to low or slow walking speeds. The limb support device can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.
