Abstract

A prosthetic foot may comprise a resilient member comprising an outer arced surface, a toe piece, a mid-stance support, and a heel support. The toe piece may be coupled to an anterior portion of the outer arced surface of the resilient member. The mid-stance support may be removably coupled to a middle portion of the outer arced surface of the resilient member. The heel support coupled to a posterior portion of the outer arced surface of the resilient member.

Claims (36)

1 . A prosthetic foot comprising:

a resilient member comprising an anterior end, a middle portion, and a posterior end;

a mid-stance support coupled to a lower surface of the middle portion of the resilient member; and

a heel support coupled to a lower surface of the posterior end of the resilient member.

2 . The prosthetic foot of claim 1 , wherein the mid-stance support is removably coupled to the resilient member.

3 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises an elastomeric material configured to be adjustable in durometer.

4 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises an elastomeric material configured to be adjustable in height.

5 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises a concave-shaped lower surface.

6 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises a convex-shaped lower surface.

7 . The prosthetic foot of claim 6 , wherein the convex-shaped lower surface comprises a radius peak located at a rear portion of the mid-stance support configured to provide a smooth transition from the heel-strike phase to mid-stance phase.

8 . The prosthetic foot of claim 6 , wherein the convex-shaped lower surface comprises a radius peak located at a forward portion of the mid-stance support configured to provide a heel strike with less tibial progression and an abrupt transition from the heel-phase to mid-stance phase.

9 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises a lower surface with a radius point located above the foot.

10 . The prosthetic foot of claim 1 , wherein the mid-stance support comprises a lower surface with a radius point located below the foot.

11 . The prosthetic foot of claim 1 , wherein the heel support comprises an elastomeric bumper and a heel lock having an angled surface.

12 . The prosthetic foot of claim 11 , wherein the elastomeric bumper is configured to be adjustable in durometer.

13 . The prosthetic foot of claim 11 , wherein the angled surface is configured to be adjustable to provide increased heel strike.

14 . The prosthetic foot of claim 1 , further comprising a toe piece coupled to a lower surface of the anterior end of the resilient member.

15 . The prosthetic foot of claim 14 , wherein the toe piece and the mid-stance support form a support surface.

16 . The prosthetic foot of claim 15 , wherein when the support surface is configured to provide support from the heal-strike phase to the toe-off phase.

17 . The prosthetic foot of claim 11 , wherein the resilient member and the angled surface of the heel support are capable of storing energy during deflection to propel the user forward.

18 . A prosthetic foot comprising:

a resilient member comprising an outer arced surface;

a toe piece coupled to an anterior portion of the outer arced surface of the resilient member;

a mid-stance support removably coupled to a middle portion of the outer arced surface of the resilient member; and

a heel support coupled to a posterior portion of the outer arced surface of the resilient member.

19 . The prosthetic foot of claim 18 , wherein the mid-stance support comprises an elastomeric material configured to be adjustable in durometer.

20 . The prosthetic foot of claim 18 , wherein the mid-stance support comprises an elastomeric material configured to be adjustable in height.

21 . The prosthetic foot of claim 18 , wherein the mid-stance support comprises a convex-shaped lower surface.

22 . The prosthetic foot of claim 18 , wherein the mid-stance support comprises a concave-shaped lower surface.

23 . The prosthetic foot of claim 21 , wherein the convex-shaped lower surface comprises a radius peak located at a rear portion of the mid-stance support.

24 . The prosthetic foot of claim 21 , wherein the convex-shaped lower surface comprises a radius peak located at a rear portion of the mid-stance support.

25 . The prosthetic foot of claim 18 , wherein the heel support comprises an elastomeric bumper and a heel lock having an angled surface.

26 . The prosthetic foot of claim 25 , wherein the elastomeric bumper is configured to be adjustable in durometer.

27 . The prosthetic foot of claim 25 , wherein the angled surface is configured to be adjustable to provide increased heel strike.

28 . The prosthetic foot of claim 25 , wherein the resilient member and the angled surface of the heel support are capable of storing energy during deflection to propel the user forward.

29 . The prosthetic foot of claim 18 , wherein the resilient member comprises a glass fiber.
