Version or model
In the FDA UDI rules, each version or model has its own device identifier. A change that takes a device outside the set limits creates a new version or model with a new UDI-DI.
Version or model means all devices that have specifications, performance, size, and composition, within limits set by the labeler.
21 CFR, 830.3
