PROSTHETIC SPACER DEVICES, SYSTEMS, AND METHODS

摘要

A prosthetic device comprises a plurality of polymer units attached to one or more leaf springs. The polymer units are spaced apart and define spaces between the units such that there is no contact between any two polymer units at maximum deflection of the one or more leaf springs. The polymer units may be impermeable to water and the spaces may facilitate free flow of liquids out of the device. The plurality of polymer units may comprise a heel piece and a toe piece. One or both of the heel piece and the toe piece may extend beneath the one or more leaf springs such that the one or more leaf springs do not contact the ground when the device is used for ambulatory movement. The toe piece may extend further down than the heel piece and may extend beneath the one or more leaf springs such that extension of the toe piece provides increased flexing of the one or more leaf springs.

主权项

1. A prosthetic device comprising:
at least one leaf spring; and a plurality of polymer units attached to the leaf spring, the polymer units being spaced apart and defining spaces between the units such that contact between any two polymer units does not interfere with deflection of the one or more leaf springs.
