What if you had a roadmap for FDA medical device approval?

With that in mind, we’ve prepared a guide highlighting the essential steps, including the regulatory framework, device classification, premarket submissions, and postmarket requirements. The goal is to simplify the process, helping manufacturers align their products with FDA standards and requirements.

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) regulates 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.

Classes of Medical Devices

Regulators categorize medical devices into three classes based on their risk level and intended use.

Class I devices are low-risk and typically 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 ensures that regulatory control aligns with the level of risk associated with a device. Regulators also assign a product code to each device, grouping similar devices based on their intended use.

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.

An additional fact: the FDA also has rules for cosmetic regulation.

Device Classification and Applicable Regulations

The FDA classifies medical devices into three classes based on risk level and necessary regulatory controls for safety and effectiveness.

This classification impacts the type of premarketing submission/application required for FDA clearance to market.

Here, we explain how to classify your device, understand listing requirements, and 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. Class I devices posing the lowest risk and Class III devices posing the highest risk.

The intended use and indications for use, found in the device’s labeling or conveyed during sale, are crucial for classification.

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.

Manufacturers must submit registration and listing information electronically, providing the FDA with crucial data on device locations for quick public health responses. This is crucial for foreign manufacturers working with 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, the lowest risk products, are subject to general controls and often exempt from premarket notification.

Devices of Class II 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).

Manufacturers must understand these controls to navigate the FDA approval process, especially with the new QMSR impacting device safety.

This framework requires manufacturers, especially those outside the U.S., to follow FDA regulations and work with U.S. agents for approval.

Premarket Submissions

Types of Premarket Submissions

For medical device manufacturers, especially those outside the U.S. needing a U.S. agent, understanding premarket submissions is essential.

There are three types: Traditional, Special, and Abbreviated 510(k)s, each serving different needs but aiming for marketing authorization.

For Class III devices or those for rare diseases, the Humanitarian Device Exemption (HDE) provides a pathway, requiring designation as a Humanitarian Use Device (HUD).

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 similar ones on the market, focusing on use, technology, and performance.

The submission process has moved towards digital, with all submissions, unless exempted, required to be electronic using eSTAR.

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. Manufacturers must submit an electronic copy (eCopy) of the submission along with a paper copy of a signed cover letter.

Humanitarian Device Exemption (HDE)

The HDE pathway is designed for devices intended to benefit patients with rare diseases or conditions. A device must first obtain HUD designation to be eligible, 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.

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.

The requirement, called establishment registration, appears 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.

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.

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.

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.

Reaching a FDA medical device approval

Throughout this guide, we’ve demystified the FDA approval process, focusing on the necessities for foreign manufacturers, particularly the need for a U.S. agent, and the importance of adhering to the new Quality Management System Regulation (QMSR).

Clearly, understanding the nuanced regulatory landscape and the specific requirements across different device classes forms the bedrock of navigating the FDA’s approval pathway.

Moreover, it’s clear that the shift towards the new QMSR underscores a strengthened emphasis on quality management, aligning with global standards to ensure the safety and efficacy of medical devices entering the U.S. market.

As foreign manufacturers endeavor to align their products with FDA standards, the significance of designating a competent U.S. agent cannot be overstated. This agent acts not just as a bridge between the manufacturer and the FDA but also as a strategic guide through the complex regulatory environment.

Consequently, embracing the new QMSR offers manufacturers an opportunity to globally harmonize their quality management systems, potentially facilitating smoother approval processes and access to a key market.

In sum, achieving FDA approval is a meticulous journey requiring detailed preparation, a deep understanding of regulatory requirements, and strategic alignment with quality standards, all of which are essential for success in the dynamic U.S. medical device market.
