Tranquillo, J., Goldberg, J., & Allen, R. (2022). Biomedical Engineering Design. Academic Press.

Chapter Summary

The book has 15 chapters on about 500 pages, grouped into sections that each open with a short introduction. Its three authors have long experience of running student design programmes: Joseph Tranquillo at Bucknell University, Jay Goldberg (who also worked in the device industry and on FDA advisory and ASTM standards work) at Marquette University and the Medical College of Wisconsin, and Robert Allen, who directed team-based design programmes at Houston, Delaware and Johns Hopkins. The publisher explains how the book is meant to be divided: the first two chapters give an overview of the design process, project management and teamwork; the chapters then follow a design sequence from problem identification to verification and validation; the first seven chapters, or parts of them, suit first-year and sophomore design classes; the next six are mainly for upper-level students; and the last two describe what industry engineers do to commercialise a device. The book received the Textbook and Academic Authors Association's Most Promising New Textbook Award in 2024.

Chapter 1: Introduction

An overview of the medical device design process that frames the rest of the book.

Chapter 2: Design Teams and Project Management

About 40 pages on working in technical teams and managing a design project, placed at the start because student projects are team projects from the first week.

Chapters 3–4: Defining the Medical Problem; Defining the Engineering Problem

The first steps of the design sequence. Chapter 3, about 40 pages, deals with understanding the clinical problem; the publisher highlights methods for identifying unmet needs. Chapter 4 turns the medical problem into an engineering one.

Chapters 5–6: Generating Solution Concepts and Preliminary Designs; Selecting a Solution Concept

Concept generation and preliminary design, followed by methods for choosing among candidate concepts.

Chapter 7: Prototyping

The last of the chapters the publisher marks as suitable for first- and second-year classes: building prototypes to explore and test a concept.

Chapter 8: Detailed Design

At about 50 pages the longest chapter, it begins the upper-level material. Among the topics the publisher singles out are applying "Design for X" and packaging design, subjects it says are rarely addressed in other biomedical design texts.

Chapters 9–10: Testing for Design Verification and Validation; Testing in Living Systems

Two chapters on testing: verification that the device meets its specifications and validation that it meets user needs, then testing in living systems, a topic the publisher lists among the book's less common inclusions together with sterilisation methods.

Chapters 11–13: Medical Device Standards and Design Controls; Regulatory Requirements; Ethics in Medical Device Design

The regulated context of device design: standards and design controls, regulatory requirements, and ethics. The publisher describes the book as showing how technical, marketing, regulatory, legal and ethical requirements shape design decisions.

Chapters 14–15: Beyond Design: The Engineer's Role in Design Transfer, Commercialization, and Post Market Surveillance; Collaborating on Multifunctional Teams to Commercialize Medical Products

The closing section moves from the student project to industry: transferring a design to manufacture, commercialisation and post-market surveillance, and how engineers work with other functions on multifunctional teams.

Key Concepts

Chapters 1–7: From Need to Prototype

• Design process: a structured sequence from identifying a problem to a tested design, which the chapters follow in order.
• Unmet clinical need: the starting point of medical device design, identified before any solution is proposed.
• Medical versus engineering problem: the distinction between the clinical problem and its translation into an engineering problem a team can solve.
• Concept selection: choosing among candidate solutions before committing to one.

Chapters 8–10: Detailed Design and Testing

• Design for X: designing with a specific later requirement (such as manufacture) in mind.
• Verification and validation: confirming that a device meets its specifications, and that it meets the needs of its users.
• Testing in living systems: evaluating a device in biological systems as part of development.

Chapters 11–15: Regulation, Ethics and Industry

• Design controls: the formal procedures that govern how a medical device is designed and documented.
• Design transfer and post-market surveillance: moving a design into production and monitoring the device after release.

Critical Analysis

Strengths

• Built for courses at more than one level. The publisher states explicitly which chapters suit first-year and sophomore classes, which are for upper-level and capstone courses, and which describe industry practice, so one book can serve a programme's whole design sequence.
• Written from experience of student design. All three authors have run design courses and programmes for many years, and the publisher stresses the many examples from both industry and academic projects, showing different routes through each stage and how decisions are documented and communicated.
• Unusual coverage. Packaging design, testing in living systems and sterilisation methods, which the publisher says are rarely covered in other biomedical design texts, are included alongside standards, design controls, regulation and ethics.
• Recognition. The 2024 Most Promising New Textbook Award from the Textbook and Academic Authors Association is independent recognition from a professional body of textbook authors.

Limitations

• Broad rather than deep on regulation. The book gives single chapters to standards and design controls, regulatory requirements and ethics; a capstone team preparing a real submission will need dedicated references.
• A first edition. With publication in 2022 and no revision so far, regulatory details such as standards versions should be checked against current sources.
• Not a single-level book. Because it serves first-year through capstone students, any one course will use only part of it, and early students may find the upper-level chapters on regulation and industry hard to place without project experience.

Where It Fits in the Course

For a course in medical device design this is the main course text: it follows a student team through the whole design sequence and states which chapters belong to which level. Ogrodnik's Medical Device Design: Innovation from Concept to Market is a comparable practical introduction that walks through a project from statement of need to market and pays particular attention to European and US classification and regulation; it is a useful second view for students outside the United States. King, Fries and Johnson's Design of Biomedical Devices and Systems covers the design process and regulatory requirements in a broader engineering-design frame.

Yock and colleagues' Biodesign: The Process of Innovating Medical Technologies takes the innovation side further, from needs finding and screening to reimbursement, business and funding strategy, and suits teams that want to take a project towards a start-up. Teixeira's Design Controls for the Medical Device Industry and Elahi's Safety Risk Management for Medical Devices are industry references on the design-control requirements and on risk management under ISO 14971; read them alongside Chapters 11–12 when a capstone project needs real documentation.

How to Use This Book

The book is for biomedical engineering students in design courses at any level, from first-year introductions to senior capstone projects, and for practising engineers who want a structured, current design process. No specific prerequisites are needed for the early chapters; the later ones assume some engineering science and a project to apply them to.

A practical plan:

• First- and second-year design courses: Chapters 1–7, read alongside the project: Chapter 2 in the first week, Chapters 3–4 while the team defines its problem, Chapters 5–6 during concept generation and selection, Chapter 7 when prototyping begins.
• Capstone or upper-level courses: review Chapters 1–7 quickly, then Chapters 8–13 on detailed design, testing, standards, regulation and ethics, timed to the stage of the project.
• Before graduating or starting in industry: Chapters 14–15 on design transfer, commercialisation and multifunctional teams.

Use the chapters as working guides rather than reading assignments: apply each method to the team's own project and record the result in the design history, since documenting and communicating design decisions is part of what the book teaches. Upper-level teams should check every standard and regulation cited against its current version.
