Indications for 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.

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.
{2}------------------------------------------------
## 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.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
