Abstract
A prosthetic device includes a phalanges portion, a metatarsals portion that is movably coupled to the phalanges portion, an ankle portion that is movably coupled to the metatarsals portion, and a calcaneus portion that is movably coupled to the ankle portion.
Claims17
A prosthetic device comprising:
- a phalanges portion;
- a metatarsals portion that is movably coupled to the phalanges portion at a first connection point;
- an ankle portion that is movably coupled to the metatarsals portion at a second connection point spaced apart from the first connection point;
- and
- a calcaneus portion that is movably coupled to the ankle portion at a third connection point spaced apart from the first and second connection points,
- wherein the first connection point includes a first recess, the second connection point includes a second recess, and the third connection point includes a third recess, and wherein a first biasing member is disposed within the first recess, a second biasing member is disposed within the second recess, and a third biasing member is disposed within the third recess.

A prosthetic device comprising:
- a phalanges portion;
- a metatarsals portion coupled to the phalanges portion at a first connection point;
- an ankle portion coupled to the metatarsals portion at a second connection point spaced apart from the first connection point;
- a calcaneus portion coupled to the ankle portion at a third connection point spaced apart from the first and second connection points;
- and
- at least one biasing member configured to bias at least one of the phalanges portion, the metatarsals portion, the ankle portion, or the calcaneus portion in a rotational direction,
- wherein the at least one biasing member includes a first biasing member that rotatably couples the metatarsals portion to the phalanges portion, a second biasing member that rotatably couples the metatarsals portion to the ankle portion, and a third biasing member that rotatably couples the calcaneus portion to the ankle portion.

A prosthetic ankle foot comprising:
- an ankle portion including a first end with a connector and a second end with a rocker having a curved surface configured to contact the ground, the first end opposite the second end;
- a metatarsals portion rotatably coupled to the ankle portion by a first biasing member;
- a calcaneus portion rotatably coupled to the ankle portion by a second biasing member, the metatarsals portion and the calcaneus portion coupled to the ankle portion on opposite sides of the rocker;
- and
- a phalanges portion rotatably coupled to the metatarsals portion by a third biasing member;
- wherein a geometry of the prosthetic ankle foot is adjustable to produce a desired roll over shape.
