Elixir's first coronary stent is manufactured from a cobalt chromium alloy, a material that has an extensive history of use in vascular implants. Cobalt chromium offers greater strength and improved visualization under fluoroscopy than stents made from stainless steel. This allows Elixir's coronary stent to have 33 percent lower strut thickness than a stainless steel stent (81 microns), without compromising radial strength and radiopacity.
