Patent Number: 8,821,589

Title: Joints for prosthetic, orthotic and/or robotic devices

Abstract: An artificial foot device may include a core, a talus body operatively coupled with the core by a first joint, and a toe operatively coupled with the core by a second joint. The first joint may provides for constrained relative movement between the talus body and the core. The second joint may provide for constrained relative movement between the core and the toe. In some embodiments, the core may include a core assembly including a core body, an Achilles sheave coupled with the core body and a toe bracket coupled with the core body. The toe bracket may be operatively coupled with the toe, and the Achilles sheave may be operatively coupled with the talus body. Constrained relative movement between the talus body and the core may substantially correspond to a coordinated movement of a first natural joint and a second natural joint during ambulation of a natural human foot.
