A Comparative Overview of Medical Device Regulatory Framework in the United States, European Union, and Russia.

By aiding in the prevention, diagnosis, monitoring, treatment, and rehabilitation of illnesses and medical conditions, medical devices are essential to contemporary healthcare. A medical device is defined by the U.S. Food and Drug Administration (FDA) as an instrument, apparatus, implement, machine, implant, in vitro reagent, or software that is intended to be used in the diagnosis, cure, mitigation, treatment, or prevention of disease without primarily accomplishing its intended purpose through chemical action or metabolism. Regulatory bodies have set up risk-based regulatory systems to guarantee the safety, quality, and performance of medical devices both before and after marketing because they differ greatly in terms of their intended purpose, complexity, and associated risk. Even though many nations adhere to globally accepted standards, firms looking to access international markets face substantial obstacles due to variations in laws, categorisation standards, conformity assessment processes, and post-market surveillance regulations. With a focus on regulatory bodies, device classification systems, approval processes, quality management standards, and post-market surveillance mechanisms, this review offers a comparative overview of the medical device regulatory frameworks in the US, EU, and Russia.

2. MEDICAL DEVICE REGULATORY FRAMEWORK IN THE UNITED STATES

2.1 Regulatory Authority

Medical devices in the US are regulated by the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act (FD&C Act). The Center for Devices and Radiological Health (CDRH) is responsible for pre-market and post-market oversight.

2.2 Classification System

US medical devices are classified into three categories based on risk:

Table 1: Medical Device classification System in US  (1)

2.3 Approval Pathways

• 510(k) Premarket Notification: Needs substantial equivalency to a predicate device for the majority of Class II devices.
• Premarket Approval (PMA): Needs substantial clinical evidence for Class III devices.

2.4 Post-Market Surveillance

• Monitoring After the Market Reporting Medical Devices (MDR).
• Adverse event reporting, inspections, and recalls.

2.5 Recent Developments

36 original Premarket approval (PMA) applications and 2,180 Premarket approval supplements were authorised by the USFDA's CDRH (Centre for Medical Devices and Radiological Health) in 2023. This significantly contributed to the 5,807 marketing submissions that were approved in 2023. (4)

2.6 Amendments

2023 Pulse Oximeter Draft Update New recommendations for improving the accuracy of pulse oximeters, especially with regard to different skin tones. It is anticipated that 21 CFR Part 820 will be modified to conform to ISO 13485:2016, a global medical device quality management system standard, in order to boost efficiency, lower regulatory barriers, and harmonise international standards.

Amendment: New recommendations to improve device performance across a range of demographics and lessen health inequalities.  (5)

3. MEDICAL DEVICE REGULATORY FRAMEWORK IN THE EUROPEAN UNION

3.1 Regulatory Authority

In the EU, medical devices are subject to Regulation (EU) 2017/745 (MDR), which is enforced by National Competent Authorities and evaluated by Notified Bodies.  (2)

3.2 Classification System

EU devices are classified into four risk-based classes:

Table 2: Medical Device classification System in EU (2)

3.3 CE Marking

CE certification permits free market access inside the EU and attests to adherence to safety and performance standards.

3.4 Clinical Evaluation & PMS

• The Clinical Evaluation Report (CER) is required.
• Post-Market Clinical Follow-up (PMCF) and Post-Market Surveillance (PMS)
• EUDAMED-based vigilance reporting.
  5. Recent Developments

The European Union's Medical Device Regulation (MDR), which went into force in April 2017, altered the European legal framework for medical devices and imposed a number of new obligations on the European Medicines Agency (EMA) and the state competent authorities. (4)

1. 6. Amendments

1. 1. EU Regulation 2024/1860-2024:  Amendment: Extended transition periods for some IVDs and phased implementation of EUDAMED (European Database on Medical Devices).

Objective: Promote transparency and expedite post-market surveillance and device tracing. (6)

1. 2. Medical equipment, especially Class I sterile/measuring devices, have longer transition periods under Regulation 2023/607-2023 of the EU Amendment: MDR (EU) 2017/745.

Objective: Due to resource constraints and certification concerns, give manufacturers extra time to adapt to MDR. (7)

4. MEDICAL DEVICE REGULATORY FRAMEWORK IN RUSSIA (8)

4.1 Regulatory Authority

• The Russian Ministry of Health's Federal Service for Surveillance in Healthcare (Roszdravnadzor) is in charge of regulating medical devices.
• Device registration, market authorisation, inspections, post-market surveillance, and vigilance operations fall under the purview of Roszdravnadzor.
• In Russia, only gadgets that have a current Registration Certificate may be sold.

4.2 Legal Framework

• Federal Law No. 323-FZ " On the Fundamentals of Health Protection of Citizens."
• Government Decree No. 1416 about medical device registration.
• Ministry of Health Order No. 4n (nomenclature and classification of medical devices).
• Applicable GOST and GOST ISO standards.
• Regulations for uniform registration under the Eurasian Economic Union (EAEU).

4.3 Classification System

Russian medical devices are classified into four risk classes:

Table 3: Medical Device classification System in RUSSIA (9. https://traccglobal.com/russia-medical-device-registration/)

4.4 Quality Management System (QMS)

• Manufacturers must put in place a Quality Management System that complies with globally accepted standards like ISO 13485.
• During the registration process, adherence to relevant Russian and EAEU quality standards is assessed.

4.5 Post-Market Surveillance

Manufacturers are responsible for:

• Monitoring After the Market Manufacturers are in charge of: Keeping an eye on the functioning and safety of devices.
• Reporting unfavourable incidents.
• Taking corrective and preventative measures (CAPA).
• When required, field safety corrective actions (FSCA) and product recalls.
• Adhering to regulations for the duration of the product's lifecycle.
