FDA PRODUCT CODE · CLASS II
KNW — Instrument, Biopsy
What these counts are not
Clearance and recall counts are SPEQ’s aggregation of FDA’s own published records for the code. A recall count is a measure of history, not of a device’s safety, neither number is an FDA rating, and SPEQ is not affiliated with the FDA.
What this classification requires
Every statement below is FDA’s own classification record for this product code, quoted from the device classification field reference. The SPEQ reading beneath each one is SPEQ’s interpretation of what it means for the work, and is not FDA text.
510(K)
SPEQ READINGA premarket notification under 21 CFR Part 807 Subpart E is the route for this code. The submission argues substantial equivalence to a legally marketed predicate, so the engineering question is which predicate the design can actually be compared against, and the evidence question is what testing supports that comparison.
Class II (moderate to high risk): general controls and special controls
SPEQ READINGSpecial controls are the distinguishing feature: performance standards, guidance documents, patient registries or postmarket surveillance named for the device type. Find the special controls before designing the test plan — they usually name the tests.
Device is eligible for The Voluntary Malfunction Summary Reporting Program
SPEQ READINGMalfunctions for this code may be reported in periodic summary form rather than as individual MDRs under 21 CFR Part 803. Eligibility is a property of the product code; using it is a decision the manufacturer makes and must be able to justify.
Not exempt due to Good Manufacturing Practice (GMP)/Quality System
SPEQ READINGThe full Quality Management System Regulation (21 CFR 820, incorporating ISO 13485:2016) applies, and is what an FDA inspection of this device will be conducted against.
Device is not implantable
SPEQ READINGNo implant-specific expectations attach from the classification itself.
Device is not used for life sustaining purposes
SPEQ READINGNo life-sustaining designation attaches to this code.
Device is a candidate for a third party review program
SPEQ READINGAn Accredited Person may conduct the 510(k) review instead of FDA. FDA still makes the clearance decision — third-party review changes who reviews, never who decides.
Other product codes under 21 CFR 876.1075
One regulation usually governs several product codes. These share this code’s regulation, and therefore its classification basis.
21 CFR 876.1075 — Gastroenterology-urology biopsy instrument
The classification regulation for this product code, as published by the Office of the Federal Register. This is the regulation text itself — no SPEQ interpretation appears in it.
(a) Identification. A gastroenterology-urology biopsy instrument is a device used to remove, by cutting or aspiration, a specimen of tissue for microscopic examination. This generic type of device includes the biopsy punch, gastrointestinal mechanical biopsy instrument, suction biopsy instrument, gastro-urology biopsy needle and needle set, and nonelectric biopsy forceps. This section does not apply to biopsy instruments that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.
(b) Classification.
(1) Class II (performance standards).
(2) Class I for the biopsy forceps cover and the non-electric biopsy forceps. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9. [48 FR 53023, Nov. 23, 1983, as amended at 61 FR 1122, Jan. 16, 1996; 66 FR 38801, July 25, 2001]

Recent recalls
Disposable biopsy instruments were potentially manufactured missing the backend notch retention feature on the needle that results in inadequate securing of the needle inside the device, which could lead to needle detachment and misplacement, which could lead to tissue damage and bleeding.
The internal diameter of the coaxial cannula may be smaller or larger than the external diameter of the biopsy needle, and the length of the cannula may exceed the stated length on the label. As a result, the biopsy needle may not fit properly into the coaxial cannula, preventing access to the targe
Diameter mismatch between coaxial and biopsy needle (cutting cannula) in disposable core biopsy instrument kits, where the coaxial cannula inner diameter prohibits the biopsy needle (cutting cannula) from properly fitting into the coaxial cannula and accessing target tissue, which may lead to repeat
The stylet is longer than specified on the label
Biopsy Systems have components that are misaligned due to an issue with the manufacturing assembly equipment, which may lead to the needle ejecting when triggered outside the body, which may result in user or patient needle stick injury.
