Abstract
A prosthetic foot device includes an ankle section with a discrete, straight section in a substantially vertical orientation with a curved section on both sides. An attachment member can be coupled to a limb of an amputee. An elongated forefoot portion can have an upper attachment section attached to the attachment member, and can extend downwardly through the ankle section positioned at an ankle location of a natural foot, and forwardly through an arch section, to a toe section positioned at a toe location of a natural foot. The first curved section can interconnect the attachment section and the straight section, while the second curved section can interconnect the straight section and the arch section.
Claims26
A prosthetic foot device, comprising;
- an elongated forefoot portion having an upper attachment section configured to be coupled to a limb of an amputee, and extending 1) at least rearwardly through the attachment section, 2) downwardly and rearwardly through a first curved section, 3) downwardly through a discrete and straight ankle section positioned at a rearmost location of the foot device and oriented substantially vertically, 4) downwardly and forwardly through a second curved section , 5) forwardly through an arch section, and 6) forwardly to a toe section positioned at a toe location of a natural foot.
A prosthetic foot device, comprising:
- a) an attachment member, configured to be coupled to a limb of an amputee;
- and
- b) an elongated forefoot portion having an upper attachment section attached to the attachment member, and extending at least rearwardly through the attachment section, downwardly through an ankle section, and forwardly through an arch section, to a toe section positioned at a toe location of a natural foot;
- and
- c) the ankle section of the forefoot portion including a discrete, straight section positioned at a rearmost location of the foot device and oriented substantially vertically;
- and
- d) the forefoot portion including a first curved section interconnecting the attachment section and the straight section, and a second curved section interconnecting the straight section and the arch section.
