Intended Use

The Mammotome® Hand-Held System is indicated for use for incisional breast biopsy including microcalcifications, masses, spiculated masses, asymmetric densities, multifocal disease, and diffused tissue. The Mammotome® Hand-Held System is for diagnostic use only and is not indicated for therapeutic use.

Device Story

Mechanical breast biopsy device; consists of disposable trocar-tipped probe, reusable holster/cable assembly, and remote control module. Inputs: manual positioning by clinician; tissue samples. Principle: vacuum-assisted radial cutting. Operation: semi-automatic/automatic modes for cutter advancement, vacuum, and specimen retrieval; microprocessor-controlled closed-loop system regulates cutter rotation and translation speed. Used in clinical settings for diagnostic tissue removal. Output: excised breast tissue samples. Benefits: lighter, more portable probe design; improved ergonomics; independent control of axial and lateral vacuum; reduced dependence on user interaction for consistent cutting performance.

Clinical Evidence

Bench testing only. Preclinical testing demonstrated satisfactory performance in breast tissue biopsy.

Technological Characteristics

Mechanical biopsy system with vacuum-assisted radial cutting. Components: disposable probe, holster/cable, remote control module. Features microprocessor-based closed-loop control for cutter speed and vacuum management. Independent axial and lateral vacuum control. Ergonomic hand-held form factor.

Indications for Use

Indicated for incisional breast biopsy in patients presenting with microcalcifications, masses, spiculated masses, asymmetric densities, multifocal disease, or diffused tissue. Diagnostic use only; not for therapeutic use.

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.

#### Device Description

The Mammotome® Hand-Held System is a mechanical breast biopsy device used in incisional breast biopsy including microcalcifications, masses, spiculated masses, asymmetric densities, multi-focal disease, and diffused tissue.

The Mammotome® Hand-Held System consists of three major components, a disposable trocar tipped needle-like probe, a reusable holster/cable assembly, and a remote, reusable control module. The following accessories are also provided with the system: a disposable vacuum tubing set and canister, a footswitch, a support arm and a cart.

#### Intended Use

The Mammotome® Hand-Held System is indicated for use for incisional breast biopsy including microcalcifications, masses, spiculated masses, asymmetric densities, multifocal disease, and diffused tissue.

The Mammotome® Hand-Held System is for diagnostic use only and is not indicated for therapeutic use.

#### Technological Characteristics

The Mammotome® Hand-Held System is a modification of the currently marketed Mammotome Biopsy System. While it represents a refinement over the first generation Mammotome with design, software and ergonomic enhancements for ease of use, the overall configuration, technology, materials and principles of operation of the proposed and marketed devices are equivalent.

The hand-held biopsy device, used with or without imaging modalities, provides for the diagnostic removal of tissue with fluid management through a combination of vacuum and radial cutting functions. The proposed and marketed devices contain the same primary components to achieve these functions: a probe, housing/holster, and a control module. The probe needle and cutter, which interface directly with the patient, are identical in both new and marketed devices.

In the proposed device, the housing is replaced by a holster and cable assembly and the motor resides in the control module. These physical changes make the probe lighter and more portable and facilitate user and patient interface.

The addition of a microprocessor and software allows the Mammotome® Hand-Held System to provide semi-automatic and automatic modes of operation for cutter advancement, vacuum, and specimen retrieval. Microprocessor control also provides closed-loop control to reduce dependence of cutter rotation and translation speed on user interaction or tissue variability.

In the marketed device, axial and lateral vacuum cannot be independently controlled. In the new device, axial and lateral vacuum can be controlled independently.

#### Performance Data

Preclinical testing was performed to ensure the device performs as intended. Testing demonstrated satisfactory performance in breast tissue biopsy.

Dear Dr. Itani:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition. FDA may publish further announcements concerning your device in the Federal Register.
