  • Polymeric stent and methods of manufacturing the same
    Patent number: 10010436
    Abstract: A method of manufacturing a polymeric stent by forming a pattern on a polymer tube with a laser, where the pattern formed on the polymer tube comprises a plurality of repeating units comprising a plurality of unit cells, each having a V-shaped configuration and polymeric stents formed by the methods. The pattern may be formed on the polymer tube (e.g., polylactic acid tube) using a second harmonic generator laser in which a wavelength ranging from 940 nm to 1552 nm is converted.
