Device Story
Bactiseal catheters are silicone drainage tubes used in CSF shunt systems to treat hydrocephalus; they divert excess CSF from brain ventricles to other body cavities (e.g., peritoneal) for reabsorption. Catheters are impregnated with rifampicin and clindamycin hydrochloride to reduce gram-positive bacterial colonization. Features include barium sulfate for radiopacity and tantalum dots for positioning; endoscopic version includes a tip slit for endoscopic placement. Used by neurosurgeons in clinical settings. Output is physical drainage of CSF. Benefits include reduced risk of shunt-related infection and effective intracranial pressure management.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including MRI safety (ASTM F2052, F2213, F2182, F2119), drug equivalency (USP standards), and drug effectiveness testing.

#### 807.92(a) (4) Device Description
The Bactiseal Catheters, Bactiseal Barium Striped Catheters and Bactiseal Endoscopic Ventricular Catheter include a ventricular and/or distal (peritoneal) drainage catheter that are used as part of a CSF shunting system to treat hydrocephalus. Both catheters are attached to the valve portion of a shunting system, which is then implanted in the patient's brain. The ventricular catheter diverts the excessive CSF from the ventricles of the brain through the valve. After passing through the valve, the excessive CSF is drained through the distal (peritoneal) drainage catheter into another part of the body, such as the peritoneal cavity, where it is reabsorbed into the bloodstream. The catheters are subjected to a treatment process by which the silicone is impregnated with two antimicrobials, rifampicin and clindamycin hydrochloride. Bactiseal silicone catheters have been shown in laboratory studies to reduce the colonization of gram-positive bacteria on the tubing surface. The catheters contain barium sulfate for radiopacity and have tantalum "dots" incorporated onto the silicone tubing to aid in positioning of the catheter. The Bactiseal Catheters and Bactiseal Endoscopic Ventricular Catheter are made of radiopaque silicone tubing, and the Bactiseal Barium Striped Catheters are made of clear silicone tubing with radiopaque striping. The Bactiseal Endoscopic Ventricular Catheter has a slit in the tip of the ventricular catheter in order for the catheter to be placed with the use of an endoscope.
#### 807.92(a) (5) Indications for Use
The Bactiseal Catheters and Bactiseal Barium Striped Catheters are indicated for use in the treatment of hydrocephalus as a component of a shunt system when draining of cerebrospinal fluid is indicated.
{5}------------------------------------------------
The Bactiseal Endoscopic Ventricular Catheter is designed for use in the treatment of hydrocephalus when shunting cerebrospinal fluid (CSF) from the ventricles of the brain.
#### 807.92(a) (6) Technological Characteristics Compared to Predicate
The proposed Bactiseal Catheters, Bactiseal Barium Striped Catheters and Bactiseal Endoscopic Ventricular Catheter have the same intended use, design, materials, sterility, and fundamental operation as the predicate devices. The proposed changes to labeling and the supplier of the clindamycin hydrochloride do not impact the technological characteristics of the devices. The changes do not raise any new questions of safety and/or effectiveness.
| Component Affected | Proposed Modification | Rationale |
|------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| Bactiseal Catheter Silicone Tubing | Integra is proposing a new supplier for clindamycin hydrochloride. The clindamycin hydrochloride is impregnated into the Bactiseal catheter silicone tubing. | Integra has made the decision to change the supplier for the clindamycin hydrochloride. Testing has been executed to confirm that the clindamycin hydrochloride from the new supplier is considered equivalent to the clindamycin hydrochloride from the current supplier based on material specification and drug efficacy. This testing |
{6}------------------------------------------------
{7}------------------------------------------------
| verified that the new source |
|----------------------------------|
| |
| does not raise any questions of |
| safety and effectiveness and |
| supports that the new source is |
| equivalent to the clindamycin |
| hydrochloride used in the |
| predicate devices as it has the |
| same characterizations based on |
| identity, formulation, |
| concentration of the |
| antimicrobial agent, method of |
| application to the device, |
| mechanism of drug release and |
| continues to meet the same drug |
| specifications. A |
| Biocompatibility Assessment |
| was performed which |
| determined that the introduction |
| of the new supplier for |
| clindamycin hydrochloride does |
| not introduce any new issues |
| related to biocompatibility and |
| additional testing would not be |
| necessary. |
### 807.92(b) 1-2: Summary of Nonclinical and Clinical Testing Performed
The following performance testing has been conducted in support of the substantial equivalence determination. The testing utilized well-established methods, including those from FDA consensus standards. All testing was performed on production equivalent devices.
| Performance Bench Test Results | |
|-----------------------------------------------------------------------------------------------|------------|
| Test | Conclusion |
| MRI Safety Testing per ASTM F2052, ASTM F2213,<br>ASTM F2182 and ASTM FF2119 | Pass |
| Drug Equivalency Testing per USP standards and USP<br>Monograph for Clindamycin Hydrochloride | Pass |
| Drug Effectiveness Testing per USP<81> and internal<br>test methods. | Pass |
## Sterilization/Cleaning
There are no changes in sterility as a result of the proposed changes. A sterilization equivalency assessment was performed comparing the predicate devices to the proposed device, using clindamycin hydrochloride from the new supplier, and the results were deemed acceptable.
## Shelf Life
There are no changes in shelf life as a result of the proposed changes.
## Animal Studies
No animal studies were required as appropriate verification of the subject devices was achieved based on the comparison to the predicate devices and from the results of the bench testing and engineering analysis.
{8}------------------------------------------------
## Clinical Studies
No clinical studies were required as appropriate verification of the subject devices was achieved based on the comparison to the predicate devices and from the results of the bench testing and engineering analysis.
#### 807.92(b) (3) Conclusion
Based upon the intended use, design, comparison to the predicate device, and testing performed, Integra LifeSciences believes that the proposed modifications to the Bactiseal Catheters, Bactiseal Barium Striped Catheters and Bactiseal Endoscopic Ventricular Catheter do not raise any new questions of safety and effectiveness, and is therefore, substantially equivalent to the predicate Bactiseal Catheters, Bactiseal Barium Striped Catheters and Bactiseal Endoscopic Ventricular Catheter.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
