Abstract: A prosthetic device and related methods having height adjustment features. A prosthetic foot includes an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use, an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device, and a height adjustable feature configured to adjust a height of the adapter relative to the support surface.

Abstract: A prosthetic device includes a footshell having a first portion and a second portion. The first portion has a first portion polymer lattice structure and the second portion has a second portion polymer lattice structure. The first portion polymer lattice structure has a first set of mechanical properties and the second portion polymer lattice structure has a second set of mechanical properties different from the first set of mechanical properties. The footshell also includes a sole attached to a bottom of the first portion and the second portion, wherein the sole is formed of a solid material.

Abstract: A prosthetic device includes a polymer lattice structure. The lattice structure includes a first surface arranged to face toward a residual limb, a second surface arranged to face away from the residual limb, a thickness between the first and second surfaces, and a variable lattice density across the thickness.

Abstract: A mandrel rod with or without rolled tubes thereon is held by four guide structures, two arranged above and two below with respect to the axis of rolling, and each being arranged on a lever, these levers are arranged in pairs to both sides of the rolling axis, and they are particularly interconnected and connected to a common drive to permit common radial retraction of the guide structure; these guide structures have basically three different positions, one of full retraction permitting a mandrel rod with rolled tubes thereon to be removed by lifting while simultaneously a fresh mandrel rod is placed into the rolling axis from below; in a second position of the guide structures they engage a mandrel rod in the rolling axis, and in the third position they form-fittingly engage a hollow on the mandrel rod in the rolling axis.
