Development Strategies for Medical Implants

Abstract

The lecture guides through the entire implant development process from concept to market. It illustrates how mitigation of risks during the development of patient-centered implants catalyzes innovations while simultaneously meeting user needs, socio-economic requirements, and economic targets. Discussions include real-world case studies and trends in orthopedics and cardiovascular surgery.

Objective

- Understanding patient-centered implant development processes within the regulatory framework as a never-ending improvement cycle. - Relevance of safety and efficacy in a risk-minimizing approach for a commercially successful implant development process - Understand the critical role of risk analysis in the design process of medical implants. - Learn how to apply “Design for” strategies to address specific risks in biocompatibility, manufacturability, functionality, and bioactivity. - Gain insights from practical examples, such as surgical implants and their real-world testing scenarios. - Discussion of state-of-the-art and actual trends in implant development in sports medicine, cardiovascular surgery, and soft tissue reconstruction and repair

Content

- Introduction to human-centered implant design. Key drivers of innovation such as clinical needs, economic and socio-economic criteria, and the role of risk mitigation in these processes. - Additive manufacturing as a typical lead innovation impacting core design and development processes. - Risk-based Design: Overview of the risks that medical implants typically face (e.g., biocompatibility, contamination, mechanical failure) and how these shape design choices. Basic introduction to Risk Analysis. - Regulatory considerations (e.g., FDA) that guide the risk management process in medical device development. - Design for Biocompatibility and Safety: Introduction to biocompatibility and sterility concept and considerations. Basics of tissue reactions, implant-body interactions, materials, and design principles aimed at minimizing adverse reactions. Introduction to biocompatibility standards and test planning - Design for Manufacturing and Validation: How manufacturing processes (e.g., additive manufacturing) introduce risks like contamination and how these can be mitigated through design. - Design for Functionality: How to address clinical needs. Verification and validation processes to prove performance and usability. - Design for Bioactivity: Introduction to surface modifications, test methods and biological response - Discussion of state-of-the-art and actual trends in implant development in sports medicine, cardiovascular surgery, and soft tissue reconstruction and repair. Commented movies from surgeries will further illustrate selected topics. Seminar: - Group seminars on selected controversial topics in implant development. Participation is mandatory. - Guest lectures on “how to market innovative implants” and “Risk analysis according to ISO 14971 incl. practical training”. (titles are tentative; to be confirmed) Planned excursions (limited availability, not mandatory, to be confirmed): Participation (as a visitor) in a life surgery (travel at own expense)
