Let's Combinate · 14 Aug 2024 · 33m

What this episode covers

David Simoens, founder of Life Science Professionals, details the equipment and subsystems required for commercial lyophilization, including chambers, condensers, refrigeration, and vacuum systems. He explains the shift toward automation, such as Robotic By-Row (RBR) systems, to meet EU Annex 1 sterility requirements, and discusses validation challenges like condenser capacity testing versus critical quality attributes. The conversation covers specialized handling for potent drugs and non-aqueous solvents, emphasizing safety interlocks, leak testing, and the risks of introducing monitoring probes that alter nucleation.

    S1E46 The ABCs of Industrial Automation | Mauricio Romero

    Mauricio Romero, a senior manager of metrology at Johnson & Johnson’s Vistakon division, discusses the practicalities of industrial automation in medical device manufacturing. He explains how to decide when to automate by weighing value against cost, highlighting a failed project where over-automation reduced flexibility, and emphasizing safety and ergonomics as key drivers. Romero details the architecture of automated systems, comparing PLC vendors like Allen Bradley and Siemens, and outlines the rigorous IQ/OQ/PQ validation process required for FDA-regulated equipment. He advises young engineers to gain hands-on experience through internships and to treat end-user technicians as the primary customers during design.

    70 - Charlie Webb from Van Der Stahl Scientific

    Charlie Webb, president of Van Der Stahl Scientific, discusses the rigorous validation and regulatory requirements of medical device packaging, explaining why the process is often more complex than the device development itself. He highlights the critical role of sterile barrier systems in preventing healthcare-associated infections, noting that over 150,000 deaths occur annually in the US due to non-sterile devices. Webb also addresses the challenge of hospitals using inadequate, unvalidated sealing equipment due to budget constraints, advocating for the adoption of microprocessor-controlled systems that ensure reproducibility and reliability.

    S6E51 Eric Richins | What It's Like Being A Packaging Engineer

    Eric Richins, a packaging engineer at Stryker with 10 years of experience, explains the complexities of medical device packaging, distinguishing between primary, secondary, and tertiary layers and the critical role of the Tyvek sterile barrier. He details the regulatory hurdles of sterilization methods like ethylene oxide and gamma radiation, and the massive documentation required for validating automated packaging lines. Richins discusses the challenges of implementing new automation, such as a carton erector that increased throughput from 400 units in three hours to one every six seconds, while managing the gap between design intent and production reality.

    Packaging Validation Best Practices

    Jeff Barrett, CEO of J-Pac Medical, explains the complexities of ISO 11607 packaging validation for sterilized medical devices, emphasizing that over a third of validations fail transit testing due to a lack of understanding regarding shipping modes. He details how companies can avoid costly 510(k) delays by conducting feasibility testing, using worst-case scenarios for sterilization, and managing labeling risks, which account for 40% of FDA recalls. Barrett highlights that sterilization validations can cost $40,000-$80,000 and take 16-20 weeks, urging engineers to integrate packaging design early in the process to prevent revalidation issues as companies scale.
