re_clearance
The FDA AI/ML device list shows a newer 510(k) K251766 (decision 2025-07-08) from SimBioSys, Inc. for a matching device line ("TumorSight Viz") — a new clearance for the same line is a change event.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device). Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.
