A significant risk (SR) device presents a potential for serious risk to the health, safety, or welfare of a subject. Significant risk devices may include implants, devices that support or sustain human life, and devices that are substantially important in diagnosing, curing, mitigating or treating disease or in preventing impairment to human health. Examples include sutures, cardiac pacemakers, hydrocephalus shunts, and orthopedic implants.
When a study is investigating a SR device, an IDE from the FDA is required. IRB review will not occur until the study has been granted an IDE from the FDA.
