Abstract
A prosthetic device for simulating the movements of a natural human ankle and foot throughout all the phases of the gait cycle and which is adapted for the removable attachment to the stump of a lower extremity amputee includes an ankle block member having an aperture in which a universal joint is disposed for allowing the ankle block member to simulate the movements to the anatomical limits of the natural human ankle. Attached to the universal joint and extending upwardly therefrom is an elongated tibial component having an upper tibial end to which is attached a tibial shock member for shock absorption of the prosthetic device during phases of the gait cycle when the prosthetic device strikes any walking surface. The prosthetic device further includes a lower and an upper mounting block which are both attached to a receiver mounted to the flat undersurface of the stump, adjustment of the lower mounting block permitting the pitch of the prosthetic device to match the pitch of the amputee's natural leg so that the prosthetic device can be aligned in gait with the amputee's natural leg for normal walking upon any terrain or surface.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
