Patent ID: 7833260

Claim:
An expandable biodegradable tubular scaffold comprising: a plurality of biodegradable first meanders forming an interconnected mesh, said mesh extending circumferentially about a longitudinal axis; wherein each of said biodegradable first meanders are manufactured from a racemic polymer which crystallizes under the strain of expansion of said tubular scaffold; a plurality of biodegradable second meanders, each of said second meanders being separate from another, and each extending circumferentially about said longitudinal axis in a single plane, said second meanders being nest in, and interconnected to, said first meanders, and a locking means, wherein the locking means is a two-part portion of one or different meandering strut elements located at proximal and distal ends of the scaffold and wherein the locking means comprises a cantilever arm hooking an oppositely shaped end piece of the scaffold.
