K171890 is an FDA 510(k) clearance for the BEXCORE Breast Biopsy System, Biopsy Needle. Classified as Instrument, Biopsy (product code KNW), Class II - Special Controls.

Submitted by Medical Park Co., Ltd. (Yongin-Si, KR). The FDA issued a Cleared decision on August 20, 2018 after a review of 420 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General & Plastic Surgery FDA review panel, regulated under 21 CFR 876.1075 - the FDA general and plastic surgery 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 General & Plastic Surgery submissions.
