Summary and Info
I couldn't put this book down. It contains a good description of instrumentation, including analog and digital filtering, signal conditioning, data acquisition. The authors' background is in cardiac care (pacemakers, etc.), and the book seems to focus a great deal on patient contact scenarios, whereas I would have preferred some discussion of instrumentation of other signals such as optical techniques (e.g. pulse oximetry), thermography, perhaps imaging technologies. It's a great book for anyone doing work with defibrillators/pacemakers, myography.
Medical Compliance: This book is a *fantastic* reference for anyone who needs to take a medical device through regulatory compliance. It includes a succint introduction to getting through the FDA mazz, plus several chapters dedicated to EMC (radiated/conducted emissions & suceptibility, etc.) and safety.
Although you'll find a decent quantity of equations and theory, the book is extremely practical and hands-on, including tons of clear schematics for various affordable test circuits (field probes, Hipot, leakage, etc.), and simple, direct approaches to testing and construction.
If you're looking strictly for a book on medical instrumentation, this is probably not enough. You won't find details of advanced filtering (e.g., adaptive noise cancellation), chopper detectors, fuzzy modeling & logic, algorithms, etc. But even though it's sparse on "design", this book is very strong on "development". Note the emphasis on FDA in this book, and very little mention of the European Medical Device directives (which, admittedly, are somewhat harmonized).
