K945578 is an FDA 510(k) clearance for the NIHON KOHDEN ZB-821 TELEMETRY TRANSMITTER. Classified as Transmitters And Receivers, Physiological Signal, Radiofrequency (product code DRG), Class II - Special Controls.

Submitted by Nihon Kohden America, Inc. (Irvine, US). The FDA issued a Cleared decision on November 14, 1995 after a review of 365 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.2910 - the FDA cardiovascular device oversight framework. 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 Cardiovascular review framework, consistent with the majority of Class II 510(k) submissions.
