TCT-187 Reduction of Strut Thickness Improves Early (up to 180 Days) Arterial Response to the Ultra-High Molecular Weight Amorphous PLLA Sirolimus-Eluting Bioresorbable Scaffolds in Normal Porcine Coronary Arteries

Mechanical strength of Bioresorbable Scaffolds (BRS) is highly dependent on strut dimensions and polymer features. Thicker struts have the potential for delivery challenges and higher thrombogenicity. Due to the inherent limitations of the first-generation PLLA, reduction of wall thickness of BRS is
