Indications for Use
BD Surgiphor™ Antimicrobial Irrigation System is intended to mechanically loosen and remove debris, and foreign materials, including microorganisms, from wounds.
Device Story
BD Surgiphor Antimicrobial Irrigation System is a 2-step wound irrigation and debridement system. It consists of two 450 mL bottles: one containing 0.5% povidone iodine solution (Surgiphor Solution) to loosen debris, and one containing sterile saline (SurgiRinse Solution) to rinse the wound. The device is used by clinicians in a clinical setting. The mechanism of action is purely mechanical: the user squeezes the bottle to dispense fluid, and the pressure of the fluid moving across the wound surface physically removes debris, foreign materials, and microorganisms. The povidone iodine acts as a preservative to prevent microbial growth within the solution bottle. The system is provided terminally sterile and is intended for single use. By facilitating the removal of wound contaminants, the device aids in wound cleansing, potentially supporting the healing process.
Clinical Evidence
Bench testing only. Evidence includes USP <51> antimicrobial effectiveness, USP <85>/<161> endotoxin/pyrogen testing, ISO 10993-1 biocompatibility, fluid pressure testing, and nonclinical wound healing studies. Sterilization validation performed per ANSI/AAMI/ISO 11137 and TIR13004. Packaging and shelf-life validated per ISO 11607, ASTM F1980, ASTM F2096, and ASTM D4169. Stability testing conducted per ICH Q1A(R2).
Technological Characteristics
Two-part system: 0.5% povidone iodine solution and 0.9% sterile saline. Applicator: Polycarbonate cap with spike on polypropylene bottle. Sterilization: Gamma irradiation (SAL 10^-6) per ANSI/AAMI/ISO 11137/TIR13004. Biocompatibility: ISO 10993-1 compliant. Preservative: 0.5% Povidone Iodine. Storage: Room temperature, avoid freezing/excessive heat.

#### Device Description:
The BD Surgiphor™ Antimicrobial Irrigation System is a 2-step system of aqueous solutions for irrigation and debridement of wounds. The 2-step process includes one bottle of Surgiphor™ Solution (0.5% Povidone Iodine) which is used first to loosen wound debris, and one bottle of SurgiRinse™ Solution (saline solution, USP 99.95%) which is used second to rinse the loosened debris from the wound. The mechanical action of fluid moving across the wound provides the mechanism of action and aids in the removal of debris, and foreign materials, including microorganisms, from wounds. The BD Surgiphor™ Antimicrobial Irrigation System is provided as a two-part terminally sterilized system with 450 mL of each solution. The povidone in the Surgiphor™ Solution serves as a preservative to ensure that no unwanted microbial growth occurs in the solution after the bottle is open.
### Indications for Use:
BD Surgiphor™ Antimicrobial Irrigation System is intended to mechanically loosen and remove debris, and foreign materials, including microorganisms, from wounds.
## Comparison of Technological Characteristics:
The subject BD Surgiphor™ Antimicrobial Irrigation System is substantially equivalent to its secondary predicate, predecessor Surgiphor Wound Irrigation System (K202071), primary predicate Irrisept® Antimicrobial Wound Lavage (K210536) and reference device, Atteris Antimicrobial Skin and Wound Cleanser (K160192).
The Surgiphor solution comprises 0.5% povidone iodine in sterile saline while the Irrisept solution comprises 0.05% chlorhexidine gluconate and the Atteris solution, polyaminopropyl biguanide (PHMB) in purified water. The composition of all three solutions acts as a preservative to inhibit microbial growth in the respective solutions.
The mechanism of action is the same between the proposed and the predicates, specifically, the mechanical action of fluid across the wound removes wound debris, including microorganisms. The mechanism of action is defined by the fluid pressure of the solution, dispensed upon a wound. which is demonstrated by testing provided in this 510(k).
The BD Surgiphor™ Antimicrobial Irrigation System is unchanged from the legally marketed predicate Surgiphor™ Wound Irrigation System (K202071) in its intended use, performance, and technological characteristics except as noted in subsequent comparison of technological characteristics table. The removal of wound debris and foreign materials, including microorganisms, is consistent with the primary predicate Irrisept® Antimicrobial Wound Lavage (K210536) and reference predicate device Atteris Antimicrobial Skin & Wound Cleanser (K160192). All three predicate devices have intended use and apply a solution to the wound for removal of wound debris and foreign materials, including microorganisms.
This 510(k) is to specify the removal of microorganisms through mechanical cleansing action within the indications for use statement of the BD Surgiphor™ Antimicrobial Irrigation System consistent with predicates Irrisept Antimicrobial Wound Lavage and the Atteris Antimicrobial Skin & Wound Cleanser.

## Performance Testing
There are no technological differences between the two versions of the Surgiphor System. The change to the BD labeled indication for use to include removal of "microorganisms" as a type of wound debris does not change the intended use of the device and does not raise new safety and effectiveness concerns. Substantial equivalence has been confirmed through performance testing as summarized below.

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.
