Premarket evidence — what FDA accepted
source quote (p.6)
“EndoNaut is a computerized navigation system consisting of a software part that carries the medical features and technologies that are controlled and can be installed on a hardware part that enables the medical device to be used in accordance with its intended purpose.”
source quote (p.12)
“Features which call machine-learning algorithms: Registration 3D/2D, Motion detection, Contrast injection detection”
source quote (p.12)
“The algorithms have not been changed. Only the way they are implemented is different between the EndoNaut Standalone Software and the EndoNaut Server Software (different architectures). These implementation changes do not change the purpose of the algorithms (they do what they did before).”
source quote (p.19)
“Verification and validation activities have demonstrated that the EndoNaut (Server) software variant performs equally as the EndoNaut (Standalone) predicate software by providing reliable results, without functional regression and moreover, offers robust safety/security mechanisms.”

sample size not stated
endpoints: meets the design specification and performed as intended; performs equally as the EndoNaut (Standalone) predicate software by providing reliable results, without functional regression
standards: ISO 14971, IEC 62304, IEC 60601-1, ANSI AAMI ES60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012 (Consolidated Text), IEC 60601-2, IEC 60601-1-6
Reported performance (0 observations)
FDA source did not state a quantitative performance metric — non-reporting is itself the signal.
Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

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.
