Device Facts

• Record ID: K022879
• Device Name: MODIFICATION TO SANARUS CENTRICA CORE TISSUE BIOPSY
• Applicant: Sanarus Medical, Inc.
• Product Code: KNW · Gastroenterology, Urology
• Decision Date: Sep 23, 2002
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 876.1075
• Device Class: Class 2

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.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 Story

System comprises sticking probe, tissue cutter, control unit, and specimen container. Probe uses cold temperatures at tip to engage target tissue; coaxially mounted cutter cores tissue specimen. Available in various gauge sizes/lengths. Used for soft tissue and breast biopsy. Physician-operated. Provides tissue samples for histologic examination. Enables partial or complete removal of imaged breast abnormalities for diagnosis. Benefits patient by facilitating diagnostic sampling of abnormalities.

Clinical Evidence

Bench testing only; no clinical data provided. Testing confirmed sample quality equivalent to predicate.

Technological Characteristics

System includes sticking probe, tissue cutter, control unit, and specimen container. Employs cryo-engagement (cold temperature) at probe tip for tissue acquisition. Coaxial mechanical tissue cutter. Available in multiple gauge sizes and lengths. Sterilization methods equivalent to predicate.

Indications for Use

Indicated for obtaining biopsies from soft tissues (liver, kidney, prostate, spleen, lymph nodes, soft tissue tumors) and diagnostic sampling of breast abnormalities. Not for use in bone.

Regulatory Classification

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.

#### (3) Device Name

Sanarus Centrica™ Rotational Core Biopsy System

#### Device Description (4)

The Sanarus Centrica Rotational Core 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 enqage 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.

#### (5) 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.

#### (7) Substantial Equivalence

The Sanarus Centrica Rotational Core Biopsy System is substantially equivalent to the Sanarus Core Tissue Biopsy System that was determined to be substantially equivalent on June 26, 2002 (reference K021137).

The Sanarus Centrica Rotational Core 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 Rotational Core Biopsy System does not raise significant new questions of safety and effectiveness.

#### (8) Performance Data Summary

Testing confirms that the quality of samples obtained with the Sanarus Centrica Rotational Core Biopsy System is equivalent to the predicate device.
