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.

Abstract: A scaffold includes a marker connected to a strut. The marker is retained within the strut by a tongue-and-groove connection. The marker is attached to the strut by a process that includes pressing a non-circular marker into a rectangular hole of the scaffold strut. The strut sidewalls are restrained to produce the tongue and groove connection.
