We have extensive experience in the characterization of materials and chemistries used in stents. Although nitinol is a commonly used alloy for stents, we have experience in the characterization of alternative metal alloys (e.g. stainless steel and MP35N). FDA has issued guidance on nickel rich implants where we have helped companies evaluate their materials. We have expertise in the following characterization studies:
Additionally, we have experience in failure analysis of metal alloys used in stent applications including fatigue resistance and hydrogen embrittlement.
