As a guiding needle in obtaining core biopsy samples from soft tissue such as liver, kidney, spleen, lymph nodes and various soft tissue lesions.
Device Story
Gangi-SoftGuard and Gangi-HydroGuard Coaxial Needles are sterile, single-use, manually operated introducer needles for soft tissue biopsy. The device consists of a cannula, a trocar stylet, and a spring-loaded blunt-tip stylet. During insertion, the blunt tip shields the sharp cannula tip to prevent trauma. Upon encountering resistance, the blunt tip retracts, exposing the sharp cannula for tissue penetration. Once resistance decreases, the blunt tip automatically springs back to shield the cannula. The Gangi-HydroGuard variant includes a hollow blunt stylet with a distal hole and a Luer hub, allowing fluid injection without removing the stylet. Used in clinical settings under imaging guidance (excluding MRI) by trained physicians. The device facilitates biopsy procedures by providing a protected path for biopsy instruments to reach targeted lesions.

#### 5.4 Device Description
Gangi-SoftGuard Coaxial Needle together with Gangi-HydroGuard Coaxial Needle forms the Gangi Coaxial Needle family. Gangi-SoftGuard Coaxial Needle and Gangi-HydroGuard Coaxial Needle are manually operated, sterile, single use coaxial guiding needles with a spring loaded blunt-tip stylet, to be used as a guiding needle for biopsy instruments in procedures in soft tissue. Gangi-SoftGuard Coaxial Needle and Gangi-HydroGuard Coaxial Needle has the same intended use.
Coaxial Needle and Gangi-SoftGuard Gangi-HydroGuard Coaxial Needle are gastroenterological, manually operated, sterile, single use coaxial introducer needles. Both Gangi-SoftGuard Coaxial Needle and Gangi-HydroGuard Coaxial Needle consists of three parts: a needle (cannula) provided with a trocar stylet, and a spring-loaded blunt tip stylet. The difference from Gangi-SoftGuard Coaxial Needle is that Gangi-HydroGuard Coaxial Needle has a Luer hub located on the blunt stylet housing and the blunt stylet is hollow and has a distal tip hole. This enables injection of fluid without the need to remove the blunt stylet.
#### Technological Characteristics ર્સ્ટ
Gangi-SoftGuard Coaxial Needle and Gangi-HydroGuard Coaxial Needle are delivered with the trocar stylet inserted in the needle (cannula). When the trocar is exchanged to the blunt stylet, the blunt tip protrudes out from the distal end of the needle (cannula) which makes the coaxial needle tip non-traumatic. shielding the surroundings from the sharp needle (cannula tip).
The position of the coaxial needle is monitored using imaging technique. If resistance or hard surface is met when using the device, the blunt tip retracts into the needle (cannula), exposing the sharp needle (cannula) tip and enabling cutting through tissue. The retraction of the blunt tip can be prevented by pressing the proximal part of the stylet (covered by a plastic cap) or the proximal Luer hub on the housing.
After cutting through the tissue with the sharp needle (cannula) and the resistance is reduced, the hollow blunt stylet tip springs back i.e., the non-traumatic tip will once again shield the surrounding tissue from the sharp needle (cannula tip).
When the targeted lesion has been reached, Gangi-SoftGuard Coaxial Needle and Gangi-HydroGuard Coaxial Needle enables biopsy to be performed per normal hospital routines.
The materials used for construction of the needles are typical for this type of medical device. The only material in direct patient contact is stainless steel AISI 304 and stainless steel AISI 302. The needles are designed in accordance with ISO 7864 - Sterile hypodermic needles for single use.

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.
