The concept of using bioresorbable intracoronary scaffolds in percutaneous coronary intervention has attracted interest since their inception, because these devices can overcome potential disadvantages of permanent metallic stents. The bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, CA, USA) has a bioresorbable polymer backbone of poly-L-lactide (PLLA) coated with the polymer poly-D,L-lactide (PDLLA) that contains and controls the release of the antiproliferative drug, everolimus. Both PLLA and PDLLA are fully bioresorbable. The BVS backbone is laser cut from a cylinder of polymer, resulting in a scaffold composed of a number of in-phase zigzag hoops linked together by three longitudinal ...
