The present invention provides a lumen support prosthesis composed of interlocking
radial modules which is fabricated fully assembled from a signal piece shape, without
welding or bonding. The prosthesis comprises at least one locking mechanism, allowing
for one-way sliding of the radial modules and expansion of the prosthesis from
a collapsed state, but inhibits radial recoil from the expanded diameter. The prosthesis
may be fabricated from biologically degradable materials which have certain medical advantages.
