The life cycle of a medical device covers the entire period of its existence, from the idea and design to decommissioning and disposal.
In Russian regulation, this path is considered as a single process of handling a medical device and is strictly controlled at each stage. Mistakes made at the beginning are almost always reflected in all subsequent stages.
It all starts with development. At this stage, the purpose of the product is formed, its risk class is determined, and the design and logic of the evidence base are laid. Decisions are already being made here that directly affect the complexity of registration. Incorrectly chosen assignment or underestimation of risks later lead to the return of documents and repeated work.
After development, the product undergoes mandatory tests. Depending on the characteristics and risk class, these are technical, toxicological, and clinical studies. Their task is to confirm the safety, stability of characteristics and compliance with the declared properties. The test results form the basis of the registration dossier and must be consistent with each other and with the technical documentation.
The next key stage is state registration. In Russia, a medical device can only be put on the market if it has a registration certificate. Registration is carried out through Roszdravnadzor according to the national procedure or according to the rules of the EAEU.
After registration, mass production begins. It must strictly comply with the registered documentation and be accompanied by a quality management system. Any changes to the design, materials, or software require an assessment of the regulatory implications and, if necessary, changes to the registration certificate.
The subsequent stage of implementation and operation includes product delivery, installation, commissioning, staff training and subsequent intended use. During the entire service life, the product is under post-registration control. The manufacturer is obliged to confirm that the product remains safe in real practice.
Maintenance takes a separate place. Many medical devices require regular maintenance and software updates. These processes are regulated by operational documentation and directly affect patient safety.
The final stage of the life cycle is the disposal of the product. Upon expiration of the service life or upon recognition of the product as unsuitable, it must be withdrawn from circulation in accordance with sanitary and environmental requirements. Disposal is carried out by specialized organizations and is also subject to documentation.
