What is a non-significant risk (NSR) device?

Non-significant risk (NSR) devices are devices that do not pose a significant risk to the human subjects. Examples include most daily-wear contact lenses and lens solutions, ultrasonic dental scalers, and Foley catheters. An NSR device study requires only IRB approval prior to initiation of a clinical study.

The IRB is tasked with granting NSR determinations, when appropriate.
