Abstract: A method of accelerated aging of bioresorbable polymer scaffolds including exposing the scaffold to water is disclosed. The scaffold is exposed to water at a controlled temperature for a selected aging time. The functional outputs, such as radial strength, expandability, and % recoil obtained from aged scaffolds predict those of real-time aging of the scaffold. The accelerated aging factor, which is the required shelf life divided by the aging time, is significantly higher for poly(L-lactide) scaffolds tested than thermal aging.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by one or more of a mechanical interference fit, a polymer coating or melt, and/or by friction. The marker can take the form of a bead, rivet or snap-in marker, or a tube deformed when attached to the strut. The strut is made from a tube. The strut has a thickness of about 100 microns.
