Patent ID: 8870968

Claim:
A prosthetic device comprising: an artificial foot, said artificial foot comprising: a thermoformed foot member having a foot member first end in a toe region of said artificial foot, a foot member second end opposite said foot member first end, at least one foot member curved section between said foot member first end and said foot member second end, a foot member outer surface extending between said foot member first end to said foot member second end, a foot member inner surface extending between said foot member first end to said foot member second end, and a foot member thickness extending between said foot member outer surface and said foot member inner surface, wherein (a) a first portion of said foot member inner surface overlaps and faces a second portion of said foot member inner surface so as to form a single overlapping foot member portion, (b) a foot member second end surface (i) extends between and connects said foot member outer surface and said foot member inner surface to one another at said foot member second end, (ii) is substantially perpendicular to both said foot member outer surface and said foot member inner surface at said foot member second end, (iii) has a foot member second end surface height dimension equal to said foot member thickness at said foot member second end, and (iv) is positioned over and facing said foot member inner surface, (c) said foot member thickness is substantially constant from said foot member second end surface along said at least one foot member curved section, and (d) said artificial foot has an artificial foot length extending along said thermoformed foot member from (i) said foot member first end in the toe region of said artificial foot to (ii) a portion of said foot member outer surface at a curved heel section in a heel region of said artificial foot; a cushioning member positioned along and extending upward from said foot member inner surface, said cushioning member operatively adapted and sized to provide a contact area for said foot member second end surface when said foot member second end surface is forced into contact with said cushioning member; and a sole member positioned along a lower portion of said foot member outer surface, said sole member extending a length of said artificial foot from said foot member first end to a heel end of said artificial foot.
