Biodegradable Braided Coronary Stents: Effects of Cross-Linking Concentrations on Surface Structure and Compressive Strength

Abstract:

This study proposes coronary stents in a manner of reticular tube, which are made by applying a braiding method. Polyvinyl alcohol (PVA) plied yarns are braided into hollow braids on a 16-spindle braid machine, followed by being cross-link treated to form the coronary stents. The surface observation and a compressive test are used to evaluate the resulting products. The test results show that cross-link treatment does not pertain to the reticular, tubular manner of the braids. However, a low cross-linking concentration results in a light shade and a greater compressive strength in the coronary stents. In addition, the acidification of the cross-linking solution affects the compressive modulus. The coronary stents presented by this study are proved to be biodegradable and have compressive strength and a reticular-and-tubular form.
