K901881 is an FDA 510(k) clearance for the VIBROMETRY SYSTEM.

Submitted by Bruel & Kjaer Instruments, Inc. (Hoffman Estates, US). The FDA issued a Cleared decision on May 31, 1991 after a review of 400 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Gastroenterology & Urology review framework, consistent with the majority of Class II 510(k) submissions.
