Intended Use
The device is indicated for use in obtaining biopsies from soft tissues such as liver, kidney, prostate, spleen, lymph nodes and various soft tissue tumors. It is not intended for use in bone. The device is also indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality. The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality (e.q., malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.
Device Description
The Sanarus Centrica II Rotational Core Biopsy System consists of a sticking needle, cutting cannula, fully integrated control unit and specimen container. The sticking needle is operated by the control unit and uses cold temperatures at its tip to engage the tissue to be sampled. The cutting cannula is coaxially mounted around the sticking needle and is used to core the tissue specimen. The cutting cannula will be available in several qauge sizes and lengths.

No
The summary describes a mechanical biopsy system and does not mention any AI or ML components or functions.

No.
The device is used for obtaining biopsies and tissue samples for diagnostic purposes, not for treating diseases or conditions.

Yes
The device is used to obtain tissue samples for "histologic examination," which is a diagnostic process used to determine the nature of abnormalities, including malignancy.

No

The device description explicitly details hardware components including a sticking needle, cutting cannula, fully integrated control unit, and specimen container.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Sanarus Centrica II Rotational Core Biopsy System is a device used to obtain tissue samples from the body. It is a tool for collecting the material that might then be used in an in vitro diagnostic test (like a histological examination).
  • Intended Use: The intended use clearly states it is for "obtaining biopsies" and "provide breast tissue samples for diagnostic sampling." This describes the act of collecting the sample, not performing a diagnostic test on the sample itself.
  • Device Description: The description focuses on the mechanical components and how they are used to extract tissue.

While the tissue samples obtained by this device are intended for diagnostic purposes (specifically, histological examination), the device itself is the means of obtaining the sample, not the diagnostic test performed on the sample.

§ 876.1075 Gastroenterology-urology biopsy instrument.

(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.
