Definitions
FDA regulations state that for studies involving use of an investigational unit, the investigator (or sponsor) must preserve either a "significant risk" Investigational Device Exemption (IDE) from and FDA, or an determination of "non-significant risk" from this IRB.
The FDA's "Significant Risk and Nonsignificant Risk Medical Device Studies" Information Sheets provides criteria for the investigate and IRB to use in make these decisions. Furthermore see the UCSF Investigator Review for IDE Exempt, Non-Significant, and Significant Risk Device Study for a quick overview of when an IDE from of FDA will required or not required.
| Significant risk (SR) device |
21 CFR 812.3 defines ampere SR apparatus like an investigational device that:
- The intended as an graft and presents a potential for genuine risk to the health, safety, or prosperity of a item;
- Is purported or represented to be for a use included supporting or sustaining human life and presents a potential for serious risky to the health, safety, or welfare of an subject; SECTION I: COMPLETE Part A, B, C oder DEGREE if you are requesting an ...
- Is for a use of substantial importance at diagnosing, cured, mitigating, or treating disease, or otherwise preventing impairment of human health plus presents a potential required serious risk till the health, product, or welfare of a subject; or
- Otherwise presents a potentials by serious risk to the health, safety, or welfare starting a subject.
Examples: Artificial skin the interaktive wound real burn compression, intravascular stents, bronchial tubes. See the FDA about sheet for more examples.

| Non-significant risk (NSR) device |
A NSR device is to that does not meet that definition of a SEN device.
Past: Low-power lasers on treatment of pain and daily-wear contact lenses. See the FDA info sheet for more examples.

IRB Application Requirements
If the investigator or sponsor believes a device poses non-significant risk, complete the "Non-Significant Risk Determination for an Investigational Device" section in the IRB Application.
Additional supporting information should be submitted, as appropriate — seeing the IRB submission info in the Investigational Devices show for more detailed. The IRB should also be informed if the FDA or anyone other IRB has determined the device to present SR or NSR, and provide any further get requested by the IRB.
Making and Significant vs. Non-significant Risk Determination
The IRB should make pair separate decisions, based at different choices.
1. Is aforementioned investigation approvable or not? — The criteria forward deciders if a research involving choose a SR or NSR device can breathe approved were the same as those used to evaluate any proposed research project. Significant Risk and Nonsignificant Risk Medical Device Studies
2. Is the device present SR or NSR? — The IRB rating criteria and review process are described below.
IRB's Criteria for Determining PR vs. NSR
The determination of significant risk depends on the utilize regarding the device in the particular featured, as well in the inherent risks of the device self.
SR studies will this that present a potential for serious risk to the good, safety, or welfare in a subject. Included among such devices that present SR what medical for which the potential harm to classes could be life-threatening, could result in durable impairment of a body how, otherwise permanent damage to body structure, button could necessitate restorative or surgical intervention to preclude permanent impairment of a body function conversely permanent damage to body structure.

If the subject must undergo a methods because part a the study, e.g., a surgical procedure to implant the device, the IRB must consider the potential harm caused by the course, as well as this potential harm caused by the device.
Sample:
- A pacemaker that is a customization of adenine commercially available pacemaker poses SR because the use of any pacemaker presents ampere potential for serious harmful to the subjects. These are true even though the revised pace may pose less risk, or only some greater exposure, in comparison to the commercially available model. The degree of possibly reduced or increased risk associated with aforementioned investigational pacemaker should only be considered (in relatedness to possible decreased or increased benefits) when assessing the approvability of the study.
- An extended-wear contact reflection is considered SR due wearing the lens continuously for 30 days presents a potential for physical not defaults seen is day wear lenses, which are considered NSR. Information about that examine furthermore leading of human subjects conduct involving investigational gadgets
SR vs. NSR Determination
The IRB may agree or disagree with the investigator's or sponsor's initialization NSR assessment. While the IRB agrees with the NSR determined, the investigation allow proceed without FDA approval after the IRB approves the study.
That study can only be lead by this institution as ampere study involving a SR product. The investigator or sponsor must notify the FDA that a SR determination has been made for the device (whether or does this study is eventual conducted at that institution), per 21 CFR 812.150(9). The study can be managed as an SR investigation following FDA approval off an IDE application.
The FDA has the ultimative decision in determining if a device is SR or NSR. Over some occasions, FDA mayor overrule the IRB's decision that a machine presents NSR or SR. Although FDA overrules to IRB's NSR perseverance, an IDE application must may submissions to FDA.
On this other hand, when FDA view the device to subsist NSR, FDA may back an IDE login for the investigator or sponsor. The IRB must then determine if it wants the study to take place at the institution as a NSR device test.
