No
The summary describes a mechanical biopsy system that uses cold temperatures and a cutter to obtain tissue samples. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices.
No.
The device is used for obtaining biopsies and tissue samples for diagnostic purposes, not for treating or curing a disease or condition.
Yes
The device is indicated for providing tissue samples for "diagnostic sampling of breast abnormalities" and for "histologic examination," which are diagnostic procedures.
No
The device description explicitly lists hardware components: a sticking probe, tissue cutter, 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 outside of the body (in vitro) to provide information for diagnosis, monitoring, or screening.
- Device Function: The described device, the Sanarus Centrica™ Core Tissue Biopsy System, is used to obtain tissue samples from the body. It is a tool for collecting the specimen, not for analyzing it.
- Intended Use: The intended use clearly states it is for "obtaining biopsies" and "to provide breast tissue samples for diagnostic sampling." This is a sample collection function.
- Lack of Diagnostic Analysis: The description focuses on the mechanism of obtaining the tissue (cold probe, cutter) and the quality of the sample for histological evaluation. There is no mention of the device performing any analysis or testing on the tissue itself to provide a diagnosis. The diagnosis is made after the tissue is obtained and examined histologically (which is a separate process, often performed in a lab).
In summary, this device is a biopsy device, which is a tool used to collect samples for subsequent in vitro diagnostic testing (like histology). It is not an IVD itself.
N/A
Intended Use / Indications for 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.g., 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™ Core Tissue Biopsy System consists of a sticking probe, tissue cutter, control unit and specimen container. The sticking probe is operated by the control unit and utilizes cold temperatures at its tip to engage the tissue to be sampled. The tissue cutter is coaxially mounted around the sticking probe and is used to core the tissue specimen. The tissue cutter will be available in several gauge sizes and lengths.

§ 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.

Substantial Equivalence (7)
The Sanarus Centrica™ Core Tissue Biopsy System is substantially equivalent to the Sanarus Core Tissue Biopsy System that was determined to be substantially equivalent on May 3, 2001 (reference K013528).
The Sanarus Centrica™ Core Tissue Biopsy System has the same indications for use and technological characteristics as the predicate device. The patient contact components and component materials for obtaining core biopsy samples in both the new and predicate device are the same. The packaging materials, packaging configurations, sterilization methods and sterility assurance level are also equivalent.
Based on the indications for use, technological characteristics and testing results, the Sanarus Centrica™ Core Tissue Biopsy System does not raise significant new questions of safety and effectiveness.
Performance Data Summary (8)
Testing confirms that the quality of samples obtained with the Sanarus Centrica™ Core Tissue Biopsy System is equivalent to the predicate device and that the use of a cooled probe to engage the tissue does not affect the histological evaluation.
