Indications for Use
PICO is indicated for patients who would benefit from a suction device (negative pressure wound therapy) as it may promote wound healing via removal of low to moderate levels of exudate and infectious materials. Appropriate wound types include: Chronic, Acute, Traumatic, Subacute and dehisced wounds, Partial-thickness burns, Ulcers (such as diabetic or pressure), Flaps and grafts, Closed Surgical incisions. PICO Single Use Negative Pressure Wound Therapy System is suitable for use both in a hospital and homecare setting.
Device Story
PICO is a portable, battery-operated negative pressure wound therapy (NPWT) system. It consists of an electric motor-driven, twin-diaphragm vacuum pump connected to a super-absorbent adhesive dressing. The system is applied to the wound site, with secondary fixation strips securing the dressing. Upon activation, the pump creates negative pressure, drawing excess fluid and infectious materials from the wound into the dressing. The device is intended for use in hospital or homecare settings by patients or clinicians. It operates for a fixed duration of 168 hours (7 days) before automatically ceasing function. By maintaining negative pressure at the wound site, the device aims to promote healing. The system is single-use and supplied sterile.
Clinical Evidence
Bench testing only. Wound model testing evaluated fluid management and negative pressure maintenance (-60 to -100 mmHg) for various dressing sizes and configurations at low (0.6 g/cm²/24h) and moderate (1.1 g/cm²/24h) flow rates. Results demonstrated that dressings maintained required pressure for at least 95% of test time. Biocompatibility assessed per ISO 10993-1 (cytotoxicity, sensitization, irritation, sub-acute toxicity, genotoxicity). Ethylene oxide residuals confirmed compliant with ISO 10993-7.
Technological Characteristics
Powered suction pump (21 CFR 878.4780). System includes twin-diaphragm vacuum pump, super-absorbent adhesive dressing, and PVC tubing. Powered by two AA lithium batteries. Operates at -60 to -100 mmHg. Single-use, sterile. Biocompatibility per ISO 10993-1; EO sterilization residuals per ISO 10993-7. Fixed 168-hour service life.
Indications for Use
Indicated for patients requiring negative pressure wound therapy to promote healing via removal of low to moderate exudate and infectious materials. Applicable to chronic, acute, traumatic, subacute, dehisced wounds, partial-thickness burns, ulcers (diabetic/pressure), flaps, grafts, and closed surgical incisions. Suitable for hospital and homecare use.

#### Device Description
PICO Single Use Negative Pressure Wound Therapy System is a small, lightweight, portable suction device consisting of an electric motor driven, twindiaphragm, vacuum pump connected to a super-absorbent, gentle adhesive dressing. The pump, dressing and secondary fixations strips are supplied sterile and single use. The dressing is applied to the wound and secondary fixation strips are placed over the outside edges to help hold the dressing in place. When the suction pump is turned on, air is pulled out of the dressing creating negative pressure and drawing excess fluid from the wound into the dressing. The pump is battery operated and is supplied with two AA lithium batteries which provide up to 168 hours (7 days) of battery life depending upon leak rate. The batteries can be replaced if required. The pump is programmed to stop working after 168 hours (7 days) of use and will not re-start after this time, even with new batteries. Negative pressure will not be applied at this point. PICO Single Use Negative Pressure Wound Therapy System is suitable for use in both a hospital and homecare setting. A carry bag is not provided with the system however will be available to order separately.

### Biocompatibility and Sterilization Testing
The biocompatibility of PICO Single Use Negative Pressure Wound Therapy System has been demonstrated through assessment according to ISO 10993-1 Biological Evaluation of Medical Devices. Appropriate tests have been conducted using PICO with Soft Port Dressing or representative samples that had been packaged and sterilised. These tests included cytotoxicity, sensitization, irritation, a sub-acute dermal toxicity study (wound healing), sub-acute toxicity and genotoxicity which assessed the PICO with Soft Port Dressing or representative materials. In addition, further endpoints have been assessed with reference to FDA quidance 'Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The secondary fixation strips, PVC tubing, connector, pump body and button are the same as previously cleared under 510(k) K151436 and 510(k) K112127. The test reports submitted in these 510(k)s are still valid and have not been included in this 510(k) notice. The results of the studies listed above confirm that the PICO Single Use Negative Pressure Wound Therapy System is safe for its intended use. In addition, ethylene oxide residual testing has been performed in accordance with ISO 10993-7 which confirms that PICO with Soft Port Dressing and fixation strips comply with the allowable residual limits for ethylene oxide (EO) and ethylene chlorohydrin (ECH).
### Electrical Safety and Electromagnetic Compatibility (EMC)
There are no changes made to the pump cleared under 510(k) K151436 Jan 28, 2016. All the electrical safety compliance certificates previously submitted are still valid.

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.
