Abstract of Disclosure A prosthetic foot characterized by a foot portion and an ankle portion. The foot portion and ankle portion may be fabricated from polymer impregnated and encapsulated laminates, including such laminates as carbon fibers and/or fiberglass or synthetic fibers such as Kevlar. The ankle portion may include an upper end positioned near or below about the location of a natural human ankle joint, a lower end, and an elongated intermediate section at least a portion of which curves downward and forward between the upper end and the lower end. The foot portion may be curved and have a heel section, an arch section and a toe section. The foot portion may be connected to a lower attachment section of the ankle portion, with at least the heel section of the foot portion extending rearwardly from the lower attachment section and below the upper end of the ankle portion.
34. A prosthetic foot, comprising:
35. The prosthetic foot of Claim 34, wherein the foot portion is connected to the lower attachment section of the ankle portion with an adhesive.
36. The prosthetic foot of Claim 34, wherein each of the ankle portion and the foot portion is fabricated from superimposed laminates maintained in operative relationship by an encapsulating polymer.
37. The prosthetic foot of Claim 34, wherein at least a portion of the elongated intermediate section is vertically oriented.
38. The prosthetic foot of Claim 34, wherein the upper end of the ankle portion is positioned at about the location of a natural human ankle joint.
39. A prosthetic foot, comprising:
40. The prosthetic foot of Claim 39, wherein each of the first support member and the second support member has a substantially rectangular transverse cross-section.
41. The prosthetic foot of Claim 39, wherein at least a portion of the elongated intermediate section curves downward and forward between the upper end and the lower attachment section.
42. The prosthetic foot of Claim 39, wherein the second support member is curved.
43. The prosthetic foot of Claim 41, wherein the second support member includes an arch section forward of the heel section.
44. The prosthetic foot of Claim 39, wherein the second support member includes a toe section terminating at the forward extremity of the second support member.
45. The prosthetic foot of Claim 44, wherein the toe section terminates at the forward extremity of the second support member at about the location of natural human toes.
46. The prosthetic foot of Claim 44, wherein the toe section extends forwardly from the lower attachment section.
47. The prosthetic foot of Claim 39, wherein the first support member and the second support member are adhesively bonded to one another.
48. The prosthetic foot of Claim 39, wherein at least a portion of the first support member is substantially vertically oriented.
49. The prosthetic foot of Claim 39, wherein the upper end is substantially vertically oriented.
50. The prosthetic foot of Claim 39, wherein the first support member terminates in a toe section at about the location of natural human toes.
51. The prosthetic foot of Claim 39, wherein the first support member is tapered between the upper end and the lower attachment section.
52. The prosthetic foot of Claim 39, wherein the second support member is tapered toward the rearward extremity.
53. The prosthetic foot of Claim 39, wherein the upper end of the first support member is positioned at about the location of a natural human ankle joint.
54. A prosthetic foot, comprising:
55. The prosthetic foot of Claim 54, wherein each of the ankle portion and the foot portion has a substantially rectangular transverse cross-section.
56. The prosthetic foot of Claim 54, wherein the foot portion includes an arch section forward of the heel section.
57. The prosthetic foot of Claim 54, wherein the ankle portion and the foot portion are adhesively bonded to one another.
58. The prosthetic foot of Claim 54, wherein the ankle portion is tapered between the upper attachment section and the lower attachment section.
59. The prosthetic foot of Claim 54, wherein the foot portion is tapered toward the rearward extremity.
60. The prosthetic foot of Claim 54, wherein the elongated intermediate ankle section includes at least a portion that curves downward and forward.
61. A prosthetic foot, comprising:
62. The prosthetic foot of Claim 61, wherein each of the ankle portion and the foot portion has a substantially rectangular transverse cross-section.
63. The prosthetic foot of Claim 61, wherein said foot portion is curved.
64. The prosthetic foot of Claim 63, wherein said foot portion includes an arch section between the toe section and the heel section, said foot portion contacting said under surface of said ankle portion along at least a portion of said arch section.
65. The prosthetic foot of Claim 61, wherein the ankle portion and the foot portion are adhesively bonded to one another.
66. The prosthetic foot of Claim 61, wherein the elongated intermediate ankle section includes at least a portion that curves downward and forward.
67. The prosthetic foot of Claim 61, wherein the toe section terminates at a forward extremity of the foot portion at about the location of natural human toes.
