摘要： 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.

摘要： The present invention relates to a biodegradable stent and a shape memory extending method thereof. According to an exemplary embodiment of the present invention, radial force of a biodegradable stent may be largely increased through the shape memory extending method of the biodegradable stent and the number of cracks may be decreased after crimping and stent inflation.
