How does Exponent leverage our unique multidisciplinary approach to help you understand your real-world performance and provide feedback on the product lifecycle?
Exponent has extensive expertise in creating and managing international multicenter programs to collect and analyze components from explanted orthopedic, spine, and cardiovascular implants, including total joint replacements, artificial discs, surgical tools, pacemakers, implantable cardioverter-defibrillators, and stents. With a team of multidisciplinary experts highly trained in failure analysis, our team has the experience to diagnosis the cause when a failure occurs.
We are well-versed in the Food and Drug Administration's expectations for clinical studies and post-market surveillance. Both require attention to retrieval analysis procedures that support a manufacturer's complaint handling process.
With accredited ISO 17025 (A2LA Certificate 2561.01, 2561.03) facilities for retrieval protocols based on ASTM F561, "Standard Practice for retrieval and analysis of medical devices and associated tissues and fluids," and ISO 12891, "Retrieval and analysis of surgical implants," Exponent's staff and laboratories are well-positioned to serve the global community.
We have participated in the development of the standards and use them to create custom protocols to ensure appropriate collection, shipping, and analysis of retrieved devices, tools, and tissues. Our team employs validated analysis techniques to assess wear and damage modes; evaluate fracture surfaces and material degradation; and quantify wear, deformation, and penetration of biomaterials. The results are compiled into reports suitable for direct submission to regulatory agencies.
Services
For 50+ years, we’ve thrived on solving unstructured problems that require bespoke solutions. Some of our services include:
• Development of customized retrieval protocols using ASTM F561 and ISO 12891 to meet regulatory requirements, complaint handling procedures, and total product lifecycle needs
• Customized design of retrieval kits (including instructions and clinical data forms) compliant with international shipping regulations
• Selection of appropriate analysis techniques based on device material, anatomical location, and function
• Evaluation of retrievals composed of traditional (UHMWPE on CoCr) bearing materials, alternative (metal and ceramic) bearing materials, or novel bearings
• Assessment of wear patterns, failure mechanisms, fractures, corrosion, degradation, penetration, and deformation
• Examination of fluid and tissue surrounding the implant, including histology, trace metal, and particle analyses
• Chemical and electrical evaluation of batteries in pacemakers and implantable cardioverter-defibrillators and associated leads
• Correlation of retrieved damage modes and mechanisms to in vitro tested devices
• Report preparation suitable for direct submission to regulatory bodies
• Response to FDA deficiency letters and other regulatory inquiries
