This device is designed to obtain tissue samples for diagnostic analysis, not to treat a disease or condition.
No
The device is a biopsy system used to obtain tissue samples for diagnostic analysis. The diagnostic analysis itself is performed on the tissue samples, not by the device directly.
No
The device description clearly outlines physical hardware components including a reusable Holster (electro-mechanical vacuum-assisted device with battery and charging base) and a single-patient use, sterile Probe with mechanical parts (trocar shaft, cutter, cannula, etc.). While software verification and validation testing is mentioned, the device is fundamentally a hardware system with integrated software, not a software-only device.
Based on the provided information, the Mammotome elite® Biopsy System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body in vitro (outside the body) to provide information for diagnostic purposes. This typically involves tests performed on blood, urine, tissue samples, etc., in a laboratory setting.
- The Mammotome elite® Biopsy System is a device used to obtain tissue samples from the breast or axillary lymph nodes. It is a tool for performing a biopsy procedure, which is an in vivo (within the body) process.
- The intended use clearly states that the system is indicated to "obtain tissue samples... for diagnostic analysis". The diagnostic analysis itself is performed after the tissue is obtained, likely using IVD methods in a laboratory. The Mammotome elite® is the instrument for acquiring the sample, not for performing the diagnostic test on the sample.
In summary, the Mammotome elite® Biopsy System is a medical device used for tissue acquisition, which is a step that precedes in vitro diagnostic testing. It is not an IVD device itself.
N/A
Intended Use / Indications for Use

Device Description
The Mammotome elite® Biopsy System consists of a reusable Holster (MEH1) and a single-patient use, sterile Probe (MEP10 and MEP13) that is used with ultrasound imaging guidance to excise and collect diagnostic samples with a single insertion of the Probe. Introducer Stylets (MEI10 and MEI13) are also available as optional accessories that can be used with the Mammotome elite® Biopsy System. 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 electro-mechanical vacuum-assisted biopsy device that consists of a rechargeable lithium-polymer battery and includes a charging base with AC power adapter. 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. The Probe body also contains two locking tabs to secure the Probe into the Holster. 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 at the proximal end of the Probe. The integrated coaxial cannula may be detached either after the biopsy and remain in the breast to retain a track to the biopsy site when placing a biopsy site identifier or prior to the procedure when used in conjunction with the Introducer Stylet. The Introducer Stylet/integrated coaxial cannula combination is an option that is available for those physicians who are trained in percutaneous needle techniques for tissue collection.

Summary of Performance Studies
Animal testing was conducted to validate the performance of the Mammotome elite® Biopsy System for acquisition of tissue, specifically for tissue sample weight, tissue transport reliability, and sample quality. An in vivo porcine animal model was used, which has historically been used to evaluate the ability for Mammotome biopsy devices for this purpose, and was used for both the predicate and proposed Mammotome elite® Biopsy Systems. All animal studies were conducted in compliance with 21 CFR Part 58, Good Laboratory Practices.
In these studies, acquisition of tissue samples from a single insertion site was evaluated against the following criteria and requirements:
- Tissue sample weight: The Mammotome elite® Biopsy System should acquire tissue sample weights that are comparable to the predicate device.
- Tissue transport efficiency: The Mammotome elite® Biopsy System should deliver similar performance as the predicate system in terms of the percent of samples acquired to the number of samples attempted.
- Sample quality: The Mammotome elite® Biopsy System should not alter the characteristics of the acquired tissue in such a way as to affect the ability to achieve optimal histological assessment and is comparable to the predicate device.
Additionally, bench testing was done to evaluate force to penetrate for the Mammotome elite® Biopsy System compared to the predicate System.
The animal and bench testing results confirm that the Mammotome elite® Biopsy System performed comparable to that of the identified predicate device.

Indications for Use

Device Name Mammotome elite® Biopsy System
Indications for Use (Describe)
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 the 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.
