A Review based on Biodegradable and Bioabsorbable Stents for Coronary Artery Disease

Abstract In the treatment of atherosclerotic vascular disease, angioplasty is widely used and has made a significant progress in the recent years. Drug-eluting stents are effective as well as raising the concerns associated like restenosis. In order to solve the problem of In-stent Restenosis; biodegradable stents are modified in such a way to superfluous permanent stent. Targeted drug delivery has more powerful impact as compared to metallic stents with thin coating of drug. Numerous research groups have investigated biodegradable materials like corrosive metals, polycarbonates, polyesters & bacterial-derived polymers for developing stents. A biodegradable stent is assumed to be ideal if it can be accurately installed under the fluoroscopic regulation and detect the target lesion with a trivial endovascular torment. Likewise, the advantages of bio-absorbable polymeric stents are not correlated with late stent thrombosis and leave no stent behind, they are completely suitable for Magnetic Resonance Imaging (MRI) and Multi-Slice Computer Tomography (MSCT) imaging. This survey covers the distinctive stent line-ups and bio-absorbable stents and their potentials.
