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: Various embodiments of methods for coating stents are described herein. Applying a composition including polymer component and solvent to a stent substrate followed by exposing the polymer component to a temperature equal to or greater than a Tg of the polymer component is disclosed. Repeating the applying and exposing one or more times to form a coating with the result that the solvent content of the coating after the final exposing step is at a level suitable for a finished stent is further disclosed.

Abstract: A stent has first and second members. The stent is supported by a mandrel in a first position such that the mandrel is in contact with the first member and the second member is spaced from the mandrel. A method for coating the stent includes spraying or drying the stent, placing the stent in a second position such that the first member is spaced from the mandrel and the second member is placed in contact with the mandrel, and spraying or drying the stent while the stent is supported by the mandrel in the second position.
