Published on May 10, 2024, this guidance clarifies the critical distinctions between servicing and remanufacturing of medical devices, specifying the regulatory responsibilities and expectations for entities engaged in these activities.
Medical devices encompass a vast array of products with different technologies, product lifecycles, complexity, intended users, and environments of use. Many devices are reusable and need preventive maintenance and repair during their useful life. For these devices, proper servicing is critical to their continued safe and effective use. However, there is a lack of clarity regarding the distinction between "servicing" and "remanufacturing" of a device. Most notably, remanufacturing has implications for the regulatory responsibilities of entities performing these activities.
This final guidance is intended to help clarify whether activities performed on devices are likely “remanufacturing.” This final guidance also clarifies existing regulatory requirements for remanufacturers and includes recommendations for information that should be included in labeling to help assure the continued quality, safety, and effectiveness of devices that are intended to be serviced over their useful life.
This comprehensive guidance comes after extensive dialogue with industry stakeholders, reflecting the FDA's commitment to transparency and collaboration. The FDA first sought public input on the issue back in 2016, inviting comments and hosting workshops to better understand industry perspectives and challenges. The culmination of these efforts is a guidance document that not only clarifies the legal distinctions between servicing and remanufacturing but also delineates the specific compliance obligations for remanufactured.
The guidance outlines that remanufacturers are subject to the same stringent regulatory requirements as original manufacturers, including mandatory registration and listing, adherence to Quality System Regulations (QSR), and the obligation to report adverse events. These measures aim to safeguard patient safety and ensure device efficacy, aligning remanufactured devices with the high standards expected of new devices.
Importantly, the guidance addresses the industry’s concerns regarding the potential for regulatory overreach and the need for clarity in the definitions that differentiate remanufacturing from routine servicing. It acknowledges the role of third-party servicers and the challenges they face in navigating the regulatory environment, emphasizing the need for balanced oversight that does not stifle innovation nor compromise safety.
Definitions and Distinctions
“Remanufacturing" is defined as the process of processing, conditioning, renovating, repackaging, restoring, or performing any other action on a finished device that significantly changes the device’s performance, safety specifications, or intended use. This definition underscores the substantial nature of the modifications that impact the core functionality or safety of the device.
Such activities typically require compliance with the full spectrum of regulatory requirements applicable to original manufacturers, including registration, listing, premarket notification or approval, quality systems, and labeling updates. This distinction is critical because it subjects remanufacturers to a higher regulatory scrutiny similar to that of original manufacturers.
Changes might include altering the software in ways that modify the device function, using different materials that contact patient tissue, changing the energy type or control mechanisms of the device, or significantly overhauling the device's hardware to enhance performance.
“Servicing” refers to the activities involved in repairing and/or performing routine maintenance on one or more parts of a finished device, post-distribution, to return it to the safety and performance specifications established by the original manufacturer and to meet its original intended use. This definition highlights the maintenance aspect of device handling without altering its original performance or safety thresholds.
These activities generally do not require the entity performing the servicing to adhere to the regulatory responsibilities that apply to manufacturers. However, they must ensure that the servicing does not inadvertently cross into the realm of remanufacturing.
Common servicing tasks include calibrating devices according to original specifications, replacing worn parts with identical components from the original manufacturer, or making minor adjustments that do not alter the fundamental operation or safety parameters of the device.
Guiding Principles for Remanufacturing
The FDA guidance outlines several guiding principles that are crucial for determining whether specific activities performed on a medical device qualify as remanufacturing. These principles serve as a framework for assessing compliance requirements and applying necessary regulatory controls.
Intended Use:
Definition: Intended use refers to the general purpose of the device or its function, which includes indications for use as defined by the original manufacturer.
Key Principle: Any modification that alters the intended use of a device is a strong indicator of remanufacturing. This could involve changes in the medical conditions the device addresses, the environment in which it is used, or the population it serves.
Assessment Approach: To assess changes in intended use, entities must compare the original device specifications with the modified device's capabilities. The activity likely constitutes remanufacturing if the modifications expand or alter these conditions.
Examples: Changing a device designed for adult use to be suitable for pediatric use or modifying a diagnostic device to detect a different set of conditions than originally intended.
Safety or Performance Specifications:
Definition: Safety specifications refer to the device's built-in measures to ensure safe operation, while performance specifications relate to the device's functional outputs as determined by the original manufacturer.
Key Principle: Modifications that significantly alter the device's safety or performance specifications are indicative of remanufacturing. These changes can be assessed individually or cumulatively.
Assessment Approach: To determine the significance of changes, entities should perform technical evaluations, including engineering analysis and validation testing. This is to verify whether the modifications could adversely affect the device's safety or alter its efficacy in achieving its intended medical purpose.
Examples: Enhancing the output power of a medical laser device, which could alter its safety profile, or changing the materials used in a heart valve, potentially affecting its performance longevity.
Regulatory Submissions:
Definition: Regulatory submissions refer to the documentation and data that must be provided to the FDA to obtain approval for marketing a medical device in the U.S., including premarket notifications (510(k)), premarket approvals (PMA), or de novo classifications.
Key Principle: Any changes to a device that might necessitate new marketing submissions to the FDA should be thoroughly evaluated, as these are strong indicators of remanufacturing.
Assessment Approach: The evaluation should focus on whether the changes affect the device in a way that could impact safety or effectiveness, requiring a reassessment of the device's market authorization status. This includes considering whether the device as modified still conforms to the predicates previously cleared or approved by the FDA.
Examples: Incorporating a new technology or novel material into an existing device that introduces new risks or uncertainties about safety and effectiveness, thus potentially requiring a new 510(k) submission or PMA.
Considerations for Software and Components
The guidance addresses specific considerations related to changes in software and hardware components of medical devices, which are critical to determining whether such modifications should be classified as remanufacturing. These considerations are meant to help entities distinguish between routine maintenance and significant modifications that could impact device function, safety, or performance.
Software Changes:
Definition: Refers to alterations in the programming or operational instructions embedded in a device.
Key Principle: Software modifications that change the device’s fundamental function or introduce new functionality typically qualify as remanufacturing. This is because such changes can significantly affect the device's safety, effectiveness, or intended use.
Assessment Approach: Entities should evaluate the scope and impact of software changes. This involves analyzing whether the modifications could introduce new risks or alter the device’s operational logic in a way that affects its intended therapeutic or diagnostic outcomes.
Examples: Upgrading diagnostic imaging software to include AI-driven analysis capabilities or modifying the software within a pacemaker to alter pacing protocols.
Exceptions: Routine software updates that fix bugs, enhance user interface, or optimize existing functionalities without introducing new features or significantly altering existing ones, typically provided by the original manufacturer, do not constitute remanufacturing.
Component Changes:
Definition: Involves modifications to the physical parts or materials that constitute a medical device.
Key Principle: Adding or altering components in ways that affect the device’s safety or performance indicates remanufacturing. This includes changes in material properties, part dimensions, or integration of new components that alter the device's basic functions.
Assessment Approach: Evaluate whether the changes in components could affect the device's structural integrity, functional outputs, or safety profiles. This might include engineering assessments and testing to compare the modified device's performance with the original specifications.
Examples: Replacing the material used in a surgical instrument from stainless steel to a high-strength composite to enhance durability or adding a new sensor to a wearable health monitor to track additional physiological parameters.
Exceptions: Replacing worn or damaged components with identical parts provided by the original manufacturer or making minor adjustments that do not materially impact the device’s performance or safety usually falls under servicing rather than remanufacturing.
Importantly, these guidelines emphasize a careful assessment of software and hardware component changes, considering their potential to introduce significant alterations to the device's intended use, safety, or performance. Entities engaged in such modifications need to rigorously document their assessments. You may need to consult with the FDA to determine if these changes meet the threshold for remanufacturing, thus requiring adherence to more stringent regulatory obligations.
Regulatory Requirements for Remanufacturers
The guidance establishes clear regulatory requirements for entities involved in remanufacturing medical devices. These requirements align with those imposed on original manufacturers, ensuring that remanufactured devices meet the same standards of safety and effectiveness.
Compliance Obligations: Remanufacturers must adhere to the comprehensive regulatory framework governing original medical device manufacturers.
Registration and Listing: Entities must register with the FDA and list their devices, which includes providing detailed information about the type of activities performed on the devices and the facilities used for these operations.

Quality System Regulations (QSR): Compliance with the FDA’s Quality System Regulation is mandatory. This includes establishing and maintaining a quality system that is appropriate for the specific medical devices designed or manufactured. The QSR covers all aspects of production, from initial design through post-market surveillance.
Quality Systems: The QSR outlines the criteria for a quality system that includes provisions for the design, production, and distribution of medical devices. These include design control, document control, purchasing controls, identification and traceability, production and process controls, acceptance activities, nonconforming product handling, corrective and preventive actions, labeling and packaging controls, handling, storage, distribution, and installation, and records and reports.
Compliance Measure: Remanufacturers must ensure that their quality systems consistently produce safe and effective devices and comply with the applicable regulations.
Premarket Approval/Notification: The type of premarket submission required depends on the risk associated with the device and the extent of the changes made during remanufacturing.
510(k) Notification: For most Class II devices and some Class I devices, a new 510(k) may be necessary if the remanufacturing alters the device’s intended use, changes its fundamental scientific technology, or introduces new risks that were not addressed in the original submission.
Premarket Approval (PMA): A PMA might be required for Class III devices or when a remanufactured device represents a significant risk. This is the most stringent type of premarket submission and requires detailed evidence of the device’s safety and effectiveness.
Assessment Process: Remanufacturers must carefully evaluate whether their modifications could significantly impact the device's safety and effectiveness, necessitating a new premarket submission. This often involves consultations with regulatory experts or directly with the FDA.
Labeling Considerations
Labeling is critical as it provides the user with essential information about the medical device, including safety, handling, and usage instructions. Any changes in a device due to remanufacturing that affect these aspects must be reflected in the labeling.
If remanufacturing changes the device’s functionality, intended use, or handling requirements, these changes must be clearly communicated through updated labeling to ensure the device can be used safely and effectively.
Labeling must comply with FDA regulations, which require labels to be accurate and not misleading and to provide adequate directions for use.
Key Elements: The updated labels and user manuals must include any new risks identified during the remanufacturing process, changes in operational parameters, or new handling instructions. Labeling should be clear, understandable, and easily accessible to the end-user, ensuring that all potential safety warnings are prominently displayed.
Assessment Process: Before the device is released, all new labeling must undergo a thorough review to ensure compliance with regulatory standards. This might include internal reviews or consultation with labeling specialists. If the device is used in non-English speaking countries, labeling and instructions may need to be translated, adhering to the local regulatory requirements concerning language in medical device labeling.
Documentation and Compliance
Comprehensive documentation is essential to demonstrate compliance with FDA requirements and to support the safety and efficacy of the remanufactured devices.
Compliance Obligations:
Record Keeping: Detailed records of all remanufacturing processes, including changes made, testing results, quality control measures, and compliance checks, must be maintained.
Transparency and Traceability: Documentation should provide a clear trace of the decision-making process, justifying why each change was made and its impact on the device’s performance and safety.
Quality Systems:
Documentation as Part of QSR: As part of complying with the Quality System Regulations, remanufacturers must document each step of the device's design and production processes. This documentation often serves as a basis for regulatory submissions and inspections.
Change Control Records: Any changes in the design or manufacturing process must be recorded in a controlled manner, documenting the rationale behind the change, the individuals approving it, and the effects of the change.
Premarket Approval/Notification:
Submission Documentation: For devices requiring a new 510(k) or PMA, detailed documentation of the remanufacturing process, along with evidence of safety and efficacy (clinical or non-clinical data), must be submitted to the FDA.
Regulatory Correspondence: Records of all communications with regulatory bodies regarding the remanufactured device should be meticulously maintained. This includes submission dates, FDA feedback, and official approvals or requests for additional information.
Assessment Process:
