Vanguard AG remanufactures single-use medical devices into CE-certified reusable products, including cooled ablation catheters, catheters with 3D mapping systems, electrophysiology devices, and surgical instruments. Hospitals and clinics in Germany, the United Kingdom, and wider Europe buy these reprocessed devices, including Leeds Teaching Hospitals NHS Trust since 2019 and approximately 1000 total customers. The remanufacturing process involves Vanguard taking ownership of returned devices, restoring them via validated methods with in-house microbiological laboratory testing and proprietary software SPMintegra developed in 2008 for sterile goods cycle control. Leadership consists of CEO Ulrike Marczak, in the role since 2022, and board member Jessica Hiltermann since 2023. The company operates from headquarters in Berlin, production sites in Friedeburg and Aschersleben in Germany, and a subsidiary Vanguard Medical Devices Limited in London.
