Medical Device Life Cycle following the Plan, Do, Check, Action model. Used by patient guard to explain medical device design and development life cycle which start with medical device regulations, then standards, then design inputs, then risk management, then design outputs, prototypes, design verification and validation, manufacturing specifications and finally design history, before the cycle starts again at regulations.

Medical Device Design and Development

Planning for the design and development of a medical device is a requirement of regulatory systems. All manufacturers of Medical Devices are required to maintain a Quality Management System, in the USA this is determined under the CFR Title 21 part 820. Within the European Union, it is placed within demonstrating certificated compliance with international standard EN ISO 13485.
