Understand the Regulatory Framework
Overview of FDA’s Role
The FDA, recognized as the oldest comprehensive consumer protection agency in the U.S., plays a pivotal role in promoting and protecting public health. This includes oversight of a wide array of products such as foods, drugs, biologics, cosmetics, animal and veterinary medicine, and tobacco. Specifically, the Center for Devices and Radiological Health (CDRH) is tasked with regulating firms that manufacture, repackage, relabel, and/or import medical devices sold in the United States. Furthermore, CDRH also regulates radiation-emitting electronic products, ranging from medical devices like lasers and x-ray systems to non-medical products such as microwave ovens and color televisions. The agency’s responsibilities extend to evaluating the safety and effectiveness of medical devices both before and after they reach the market, ensuring patients and providers have timely, continued access to these essential tools[10][11].
Classes of Medical Devices
Medical devices are categorized into three classes based on the level of risk they pose and their intended use. Class I devices are considered low-risk and, in most cases, are exempt from Premarket Notification 510(k). Class II devices, which pose a moderate risk, generally require Premarket Notification 510(k). The highest risk devices, Class III, necessitate Premarket Approval (PMA). This classification system is designed to ensure that the degree of regulatory control is proportional to the level of risk associated with a device. Each device is also assigned a product code that groups similar devices together based on their intended use[10][7][8].
Key Regulatory Requirements
Manufacturers of medical devices intended for distribution in the U.S. must adhere to several regulatory requirements. These include establishment registration, medical device listing, Premarket Notification 510(k) unless exempt, or Premarket Approval (PMA), Investigational Device Exemption (IDE) for clinical studies, adherence to the Quality System (QS) regulation, compliance with labeling requirements, and Medical Device Reporting (MDR). These regulations are part of the FDA’s efforts to ensure that medical devices on the market are safe and effective for their intended use. Additionally, the FDA monitors the safety and efficacy of regulated marketed devices through programs like MedWatch, which allows for the reporting of serious problems related to the use of drugs and medical devices[10][5].
Device Classification and Applicable Regulations
The FDA has established a comprehensive system for classifying medical devices into three distinct classes based on the level of risk they pose and the regulatory controls necessary to assure their safety and effectiveness. This classification impacts the type of premarketing submission/application required for FDA clearance to market. Here, we delve into how to classify your device, understand device listing requirements, and grasp the regulatory controls for each class.
Classify Your Device
To determine your device’s classification, you must consider its intended use and indications for use. The FDA categorizes devices into Class I, II, or III, with Class I devices posing the lowest risk and Class III devices posing the highest risk. The intended use and indications for use, which can be found in the device’s labeling or conveyed orally during the sale, play a crucial role in this classification[13][19][20][21]. For foreign manufacturers, identifying the correct classification is a critical step, especially when designating a U.S. agent for compliance purposes. Additionally, the new Quality Management System Regulation (QMSR) emphasizes the importance of aligning device classification with quality management expectations.
Device Listing Requirements
Manufacturers must register their establishments and list their devices with the FDA, a process known as establishment registration. This annual requirement helps the FDA monitor the production and distribution of medical devices intended for the U.S. market. The registration and listing information must be submitted electronically, providing the FDA with crucial data on where devices are made and enabling a swift response to public health emergencies[16][17][18]. This step is particularly important for foreign manufacturers who need to work closely with their designated U.S. agents to ensure compliance.
Regulatory Controls for Each Class
Each class of devices is subject to a specific set of regulatory controls. Class I devices, which include products with the lowest risk, are subject to general controls, and many are exempt from premarket notification. Class II devices require general controls and special controls due to their moderate to high risk. Class III devices, which carry the highest risk, are subject to general controls and premarket approval (PMA)[13][19][20]. Understanding these controls is essential for manufacturers to navigate the FDA approval process effectively, particularly in light of the new QMSR, which may introduce additional considerations for ensuring device safety and effectiveness.
This framework, designed to protect public health, requires manufacturers, especially those based outside the U.S., to closely follow FDA regulations and work with designatedU.S. agents to successfully navigate the approval process.
Premarket Submissions
Types of Premarket Submissions
For medical device manufacturers, especially those outside the U.S. needing a U.S. agent, understanding the types of premarket submissions is crucial. There are three main types: Traditional, Special, and Abbreviated 510(k)s, each serving different circumstances but aiming for the same goal – marketing authorization through the 510(k) Program[25]. Additionally, for Class III devices or those intended for rare diseases, the Humanitarian Device Exemption (HDE) offers a pathway, requiring designation as a Humanitarian Use Device (HUD)[23].
Preparing a 510(k) Submission
When preparing a 510(k) submission, manufacturers must demonstrate their device is “substantially equivalent” to a legally marketed device. This involves comparing the new device to one or more similar devices already on the market, focusing on intended use, technological characteristics, and performance testing[23][24][27]. The submission process has moved towards digital, with all submissions, unless exempted, required to be electronic using eSTAR[26].
Premarket Approval (PMA) Process
The PMA process is the most stringent type of premarket submission. Manufacturers must provide scientific evidence demonstrating the safety and effectiveness of the device for its intended use. This process includes submitting detailed information such as device description, summary of clinical and nonclinical data, and marketing history. An electronic copy (eCopy) of the submission is required, alongside a paper copy of a signed cover letter[30].
Humanitarian Device Exemption (HDE)
The HDE pathway is designed for devices intended to benefit patients with rare diseases or conditions. To be eligible, a device must first obtain HUD designation, indicating it is intended for a condition affecting no more than 8,000 individuals in the U.S. per year. The HDE application must demonstrate the device’s probable benefit outweighs the risk of injury or illness, a key difference from the PMA process. Importantly, HDE devices are exempt from demonstrating effectiveness, focusing instead on probable benefit[31][32][33].
Postmarket Requirements
Establishment Registration
Owners or operators of establishments involved in the production and distribution of medical devices intended for use in the U.S. must register annually with the FDA. This requirement, known as establishment registration, is outlined in Title 21 CFR Part 807. The registration process includes paying an annual fee, with no waivers or reductions for small establishments. Registration and listing provide the FDA with crucial information on where devices are manufactured, enhancing the nation’s response to public health emergencies[34][35]. The registration must be completed electronically through the FDA’s Unified Registration and Listing System (FURLS)/Device Registration and Listing Module (DRLM), using an account ID and password. The process is a two-step one, where the fee must be paid before completing the registration. The FDA requires all registration and listing information to be submitted electronically, unless a waiver is granted[35].
Quality System Regulation (QSR)
Manufacturers must adhere to quality systems, known as current good manufacturing practices (CGMPs), as per 21 CFR part 820. These regulations apply to finished device manufacturers intending to commercially distribute medical devices. The QS regulation does not prescribe detailed manufacturing processes but provides a framework for manufacturers to develop procedures appropriate to their devices. Certain devices are exempt from GMP requirements, but manufacturers are still required to maintain complaint files and records. The recent amendment, the Quality Management System Regulation (QMSR), aligns the CGMP requirements more closely with the international consensus standard ISO 13485, clarifying certain expectations and concepts used in ISO 13485[37][39].
Medical Device Reporting (MDR)
The FDA mandates manufacturers, importers, and device user facilities to report certain device-related adverse events and product problems under the Medical Device Reporting (MDR) regulation (21 CFR Part 803). This regulation is a critical tool forpostmarket surveillance, helping the FDA monitor device performance and detect potential safety issues. Mandatory reporters must submit reports for adverse events that may have caused or contributed to a death or serious injury. Additionally, healthcare professionals, patients, caregivers, and consumers are encouraged to submit voluntary reports of significant adverse events or product problems with medical devices to MedWatch, the FDA’s Safety Information and Adverse Event Reporting Program. Compliance with MDR is verified to ensure that the FDA’s Surveillance Program receives timely and accurate information[40][41].
