K211543 is an FDA 510(k) clearance for the Wei Nasal Jet Tube. Classified as Tube, Tracheal (w/wo Connector) (product code BTR), Class II - Special Controls.

Submitted by Well Lead Medical Co., Ltd. (Guangzhou, CN). The FDA issued a Cleared decision on July 21, 2022 after a review of 428 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.5730 - the FDA anesthesiology and respiratory device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Anesthesiology submissions.
