Medicine does not stand still. You want innovation; you want progress. But you also want safety. Despite the fact that stents are major breakthrough in the treatment of obstructive coronary artery disease, the device will remain as permanent implant/foreign
body inside the artery after their intended use. There exists several questions till date; why should a device implanted just to prevent acute or sub-acute recoil occurring mainly after the initial days of procedure, and to deliver anti-proliferative dugs to prevent cell proliferation which is observed after 2-3 weeks of intervention, for life time? Issues with long term stay of stents in the artery include but not limited to, late restenosis, mechanical blockages, late development of malaposition, etc. which made researchers to develop Biodegradable and Bioabsorbable stents. Most bioresorbable stents are made of polylactic acid, a naturally dissolvable material that is used in medical implants such as dissolving sutures.
