It is a mesh-like tube of thin wire. The first stents licensed for use in cardiac arteries were bare metal – often 316L stainless steel. More recent ('2nd generation') stents use cobalt chromium alloy.[1] The first stents used in gastrointestinal conditions of the esophagus, gastroduodenum, biliary ducts, and colon were plastic; bare metal stents were first brought into the clinic in the 1990s.[2] Drug-eluting stents are often preferred over bare-metal stents because the latter carry a higher risk of restenosis, the growth of tissue into the stent resulting in vessel narrowing.[3] Examples
