Intelligent Tubing for Bioresorbable Scaffolds

Bioresorbable stent scaffolds are balloon-expandable and have been used to replace metallic stents to treat the narrowing of arteries and airway passages. Like traditional metallic scaffolds, bioresorbable scaffolds provide artery and/or airway support and act as a delivery system for the controlled release of an anti-inflammatory drug to prevent narrowing of the vessel lumen. Unlike metallic scaffolds that are permanent, bioresorbable scaffolds degrade over time and are completely absorbed and eliminated from the body after they are implanted, and therefore eliminate the need for additional surgical procedures. Bioresorbable scaffolds are used in coronary, peripheral, neural, and nasal applications. Each application has different scaffold sizes (OD and wall thicknesses), vessel support requirements, and degradation times.
