Blazer’s unique dual helix design provides natural conformability and enormous radial strength without comprising its extreme flexibility. Each individual cell can be dilated up to 4.5mm for side branch access. The Blazer is L605 cobalt chromium, which has no molybdenum and less nickel than 316L stainless steel and MP35N cobalt chromium. Some patients are allergic to both nickel and molybdenum and can develop restenosis as a result.
