Intended Use

The Mammotome® elite Biopsy System is indicated to obtain tissue samples from the breast or axillary lymph nodes for diagnostic analysis of breast abnormalities. The Mammotome® elite Biopsy System is intended to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality. The Mammotome® elite Biopsy System is intended to provide breast tissue for histologic examination with partial removal of a palpable abnormality. The extent of a histologic abnormality cannot always be readily determined from palpation or imaged appearance. Therefore, the extent of removal of the palpated or 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. In instances when a patient presents with a palpable abnormality that has been classified as benign through clinical and/or radiological criteria (e.g., fibroadenoma, fibrocystic lesion), the Mammotome® elite Biopsy System may also be used to partially remove such palpable lesions. Whenever breast tissue is removed, histological evaluation of the tissue is the standard of care. 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

Mammotome® elite Biopsy System is a handheld, vacuum-assisted biopsy device; used by physicians for diagnostic tissue sampling of breast or axillary lymph nodes. System consists of a reusable electromechanical holster (containing rechargeable lithium-polymer battery) and a single-patient use, sterile probe. Probe features an outer trocar shaft, telescoping inner hollow coaxial cutter, and integrated coaxial cannula. During operation, vacuum pulls tissue into a distal needle aperture; sharpened inner cutter rotates at high speeds to excise tissue; vacuum transports sample to a proximal collection cup. Integrated cannula may remain in the breast to mark the biopsy site. Device eliminates need for external control modules found in predecessors by miniaturizing components into the holster. Output is a tissue sample for histologic examination. Benefits include ergonomic design, ease of use, and ability to collect diagnostic samples with a single probe insertion.

Clinical Evidence

Bench testing only. Side-by-side comparison of the subject device and predicate devices performed using ex vivo and in vivo models. Evaluated criteria included tissue sample weight, tissue transport reliability, and sample quality. Results confirmed the subject device retrieves tissue samples comparable to the predicate devices.

Technological Characteristics

Handheld electromechanical vacuum-assisted biopsy system. Components: reusable holster (rechargeable lithium-polymer battery, AC power) and single-use sterile probe (trocar shaft, coaxial cutter, coaxial cannula). Sensing/Actuation: vacuum-assisted tissue acquisition and high-speed rotational/translational cutting. Connectivity: standalone. Sterilization: sterile probe. Software: integrated firmware for cutter advancement, specimen retrieval, and transport.

Indications for Use

Indicated for patients requiring tissue sampling of breast or axillary lymph nodes for diagnostic analysis of imaged or palpable breast abnormalities, including partial or complete removal of imaged abnormalities and partial removal of palpable benign lesions.

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 Mammotome® elite Biopsy System is composed of a reusable Holster and a single-patient use, sterile Probe that may be used with ultrasound imaging guidance to excise and collect diagnostic samples with a single insertion of the Probe. The components of the system are designed to operate safely when used together for diagnostic sampling of tissue during a biopsy procedure. The Holster is a self-contained, handheld, reusable electromechanical vacuum-assisted biopsy device that consists of a rechargeable lithium-polymer battery and includes AC power cord and accessories. The Probe consists of an outer trocar shaft, a telescoping inner hollow coaxial cutter and an integrated coaxial cannula. The Probe incorporates a distal needle aperture and a proximal specimen collection cup with a tissue sample basket and specimen collection cap. The Holster contains one alignment tab that inserts into the holster notch located on the body of the Probe body also contains two locking tabs to secure the Probe into the Holster creates vacuum inside the device to assist in pulling tissue into the aperture while the sharpened inner cutter rotates at high speeds and extends across the aperture to acquire targeted tissue. The tissue sample is transported by vacuum to the specimen collection cup. The integrated coaxial cannula may be detached after the biopsy and remain in the breast to the biopsy site when placing a biopsy site identifier.

Intended Use: The Mammotome® elite Biopsy System is intended to provide breast or axillary lymph node tissue samples for diagnostic analysis of imaged or palpated breast abnormalities.

## Technological Characteristics:

The Mammotome® elite Biopsy System, used with or without imaging modalities, facilitates the diagnostic removal of tissue through a combination of vacuum and rotational/translational cutting functions. The Mammotome® elite Biopsy System utilizes the same primary components as identified in predicate devices to achieve its intended use: a Probe and housing/Holster and control module componentry.

The Probe needle and cutter are similar in both the Mammotome®elite Biopsy System and predicate devices. The need for the stand alone control module in the predicate device (Mammotome® EX Hand Held System) has been removed through the miniaturization of the components now self-contained in the Mammotome® elite Biopsy System Holster. These physical changes make the Probe/Holster more ergonomic and facilitate ease of use by physicians.

Software was created and integrated into the device (firmware) to eliminate the need for a stand-alone control module and provide the Mammotome®elite Biopsy System the capability for cutter advancement and specimen retrieval, transport and harvesting.

Supplied vacuum is used in the harvesting and transporting of acquired tissue samples, obviating the need for the mechanical specimen transport.

#### Performance testing:

To demonstrate substantial equivalence of the proposed device to the two identified predicate devices, side-by-side comparison of tissue sample collection, using both ex vivo and in vivo models, was performed. These models have historically been used to evaluate the ability for Mammotome® breast biopsy devices to collect tissue samples.

The Mammotome elite Biopsy System and the two identified predicate devices were each used to obtain tissue sample was evaluated against the following criteria:

- Tissue sample weight
- . Tissue transport reliability
- . Sample quality

Testing results confirmed that the Mammotome elite Biopsy System would retrieve a tissue sample comparable to that of the identified predicate devices.

Conclusion: The claim of substantial equivalence of the Mammotome® elite Biopsy System to the predicate devices is based on the comparison of the intended use, product technical characteristics, and performance characteristics.
