摘要： 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.

摘要： A strut pattern of an endoprosthesis includes a plurality of W-shape cells that define a tubular body, the W-shaped cells at the opposite ends of the tubular body have a modified configuration that is different than the W-shaped cells at the middle portion of the tubular body. At the distal end of the tubular body, the W-shaped cells have crests with axial positions that are axially spaced apart, and have troughs with circumferential positions that are spaced apart. At the intermediate and distal end of the tubular body, the W-shaped cells crests with axial positions that coincide and have troughs with circumferential positions that coincide. The strut pattern is cut from a tubular precursor construct made of PLLA that has been radially expanded and axially extended by blow molding.
