Patent ID: 7410503

Claim:
A prosthetic foot comprising: a continuously longitudinally extending foot keel having longitudinally aligned forefoot, raised midfoot, and hindfoot portions; a resilient, monolithically formed shank extending upwardly from the raised midfoot portion of the foot keel, by way of an anterior facing continuous convexly curved surface which extends over at least most of the length of the shank and has increasing radius of curvature defining an ankle joint area and a curvilinear prosthetic part of a leg extending substantially upward above human ankle joint height and the ankle joint area, the shank having a proximal portion for connection with a lower extremity prosthetic structure adapted to be secured to a person's residual limb; wherein the ankle joint area and the prosthetic part of a leg formed by the shank are anterior facing convexly curved and provide means for sagital, anterior dorsiflexion and, posterior plantarflexion motion capabilities in response to a ground reaction force created in a person's gait in the prosthetic foot; wherein the shank and the entire foot keel are monolithically formed; and wherein the anterior facing continuous convexly curved surface extends the entire length of the ankle joint area and curvilinear prosthetic part of a leg defined by the shank.
