RECENT TRENDS IN BIOMATERIALS USED FOR CARDIOVASCULAR STENTING
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2013, Vol 4, Issue 5
Abstract
During the last decade, biodegradable metal stents have been established and examined as substitutes for the currently-used long-lasting cardiovascular stents. Degradable metallic substances could theoretically change corrosion-resistant metals presently used for stent application as it has been presented that the role of stenting is short-term and inadequate to duration of 6–12 months after joining during which arterial makeover and curing occur. Even though corrosion is usually measured as a failure in metallurgy, the corrodibility of guaranteed metals can be an advantage for their use as degradable implants. The applicant materials for such function should have automatic properties preferably close to those of 316L stainless steel. Non-toxicity of the metal itself and its ruin products is another condition as the stuff is immersed by blood and cells. Based on the mentioned necessities, iron-based and magnesium-based alloys have been the investigate candidate for biodegradable stents. Carotid angioplasty and stenting (CAS) has become known as a useful substitute to carotid endarterectomy and Nitinol stents are normally helpful in CAS. This article reviews the recent developments in the design and assessment of metallic material for biodegradable stents. It also introduces the new metallurgical process which could be practical for the manufacture of metallic biodegradable stents and their consequence on the properties of the metals.
