Abstract: Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.

Abstract: A method of laser machining a polymer construct to form a stent that includes a bioresorbable polymer and an absorber that increases absorption of laser energy during laser machining. The laser cuts the tubing at least in part by a multiphoton absorption mechanism and the polymer and absorber have a very low absorbance or are transparent to light at the laser wavelength.

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: The present invention involves laser machining polymer substrates to form a stent with laser parameters that minimize damage to the substrate in a surface region adjacent to the machined edge surface. The wavelength and pulse width are selected for this unique application and they can be controlled to minimize the surface modifications (such as voids, cracks which are induced by the laser-material interaction) which contribute to the variation in mechanical properties with distance from the edge surface, bulk mechanical properties, or a combination thereof.
