Overcoming Submission Deficiencies due to Biocompatibility

Global Medical Device Podcast · 1 Sept 2022 · 29m · Episode 278

What this episode covers

Chris Parker, Associate Department Head of In-Vivo Biocompatibility at LabCorp (formerly Toxikon), explains how medical device manufacturers can avoid and resolve FDA submission deficiencies related to biocompatibility. He details the two primary paths for addressing deficiencies—risk assessment/memo or retesting—and emphasizes the importance of proactive engagement with regulatory bodies and toxicologists during the early prototyping phase. The discussion covers material screening for Prop 65 and European CMR regulations, the challenges of testing small-surface-area devices like stents, and the financial impact of remedial work on company timelines.

    232 - MedTech Material Selection: Cost, Compliance, Sustainability, and Biocompatibility Risk

    Lucas Pianegonda, founder of Gradical, explains why medtech companies must move away from defaulting to legacy materials or molder preferences toward a structured, data-driven material selection framework. He details how early decisions on polymers like polycarbonate or PTFE impact total cost of goods, regulatory compliance, and sustainability, warning that late changes can cause multi-year delays and expensive retooling. The conversation covers the distinction between material grades and device-level biocompatibility, the risks of PFAS and additives, and the specific requirements of ISO 10993 for toxicological evaluation.

    012 - "Asking then Seeing" with Sara Waxberg Mcnew

    Sara Waxberg McNew, Chief Scientific Officer at Design Science, explains the human factors process for medical devices, emphasizing the distinction between formative studies and summative validation. She details how to interpret ANSI/AAMI HE75 and IEC 62366-1 standards, manage risk for combination products, and handle regulatory submissions with the FDA. The discussion covers specific challenges like testing rare patient populations, using surrogates, and conducting threshold analyses for generics.

    Elad Einav | How To Engineer Covered Medical Device Stents

    Elad Einav, Co-Founder and CEO of Medibrane, a medical device CDMO specializing in polymer covers for stents, explains the engineering challenges of attaching membranes to metal scaffolds. He details the tradeoffs between traditional sewing, ePTFE sintering, and adhesive-assisted lamination, emphasizing that the covering process must be treated as a composite material design input from day one rather than a downstream manufacturing step. Einav shares examples of field failures, such as stent fractures where the covering remained intact, to illustrate why early integration of material selection, manufacturing processes, and regulatory strategy is critical for clinical success.

    035 - “Safety is Safety” with Khaudeja Bano

    Dr. Khaudeja Bano, Vice President of Combination Product Quality at Amgen, explains the regulatory and cultural challenges of implementing 21 CFR Part 4 Subpart B for combination products like auto-injectors and prefilled syringes. She details the specific post-market safety reporting (PMSR) requirements, including 15-day and 30-day timelines, and how manufacturers must integrate drug and device safety data. Bano discusses the industry's struggle with mindset shifts, moving from treating device components as simple container closures to embracing design controls and cross-functional collaboration to ensure patient-centric safety.
