#### Predicate Device
Edwards Lifesciences Pressure Monitoring Kit with TruWave Disposable Pressure Transducer has been chosen as the predicate device for this pre -market application.
The filing of the 510(k) associated with this pre dicate device is K832907, filed by American Pharmaseal, a Baxter Edwards company, for a blood pressure transducer including a continuous flush device, marketed by Edwards Life sciences .
## Description of the Device
Sentra's 'TruePulse' Invasive Pressure Mon itoring Kits are indicated for use in physiological, invasive pressure measurement, and are for use with patients requir ing intravascular pressure monitoring.
The True Pulse Disposable Blood Pressure Kit from Sentra medical d evices LLC consists of a Arterial extension line (available in various standard lengths) is attached via a luer connection to the catheter that is inserted into the patient, (the male portion of the lumen is a part of the kit and the female portion of the lumen is a part of the catheter is not a part of this device) a stopcock, a monitoring line, to another stopcock, a transducer, a continuous flow flush device, and an IV set all connected by standard luer connections.
The device functions by continuously monitoring changes in blood pressure from the function of the heart. The pressure waves generated in the heart are transmitted through the vacult of system, to the catheter and then through the saline fluid - filled tubing to a transducer. Up on reaching the transducer, pressure waves from the fluid pathway depress a diaphragm, changing the resistance to the flow of current through a circuit. The change in resistance produces an electrical event that creates a signal that is then transmitted t o a monitor through a cable and displaying pressure reading and a wave form on a monitor. (The cather and monitor are not parts of this kit).

### Intended Use
Usually patients who require this type of monitoring have one of two major common factors. failure of the heart to pump effectively or a major disturbance of the circulatory system. The heart failure can be the result of several diseases such as acute myocardial infarction, long-standing valve disease, and cardio-myopathy. Major disturbances of the circulatory system may be major blood loss due to trauma, major surgery, or excessive fluid shifts within the body.
#### Comparison of the True Pulse Disposable Blood Pressure Kit to the predicate device.
The True Pulse Disposable Blood Pressure Kit is being compared to the Edwards Life sciences Pressure Monitoring Kit with TruWave Disposable Pressure Transducer ( Ref: PX260). Components of each kit are described in the table below.

Edwards TruWave transducer housing has integrated in it, a stop-cock and flush device while in Sentra's design these items are stand-alone. The reason for integration in Edwards design is cost savings and the two kits were found to be substantially equivalent in function.
The two kits were found to be substantially equivalent based on the following functional tests performed on 4 samples each of the two devices.
- . Luer inspection per ISO 594
- . De-bubbling and leak
- Output flow .
- Transducer Zero setting
- Square wave response .
- Prolonged exposure dwell with 300 mmHg saline pressure, and pressure accuracy during . and after prolonged exposure
- . Volume of kit CC
This bench testing of the Sentra Kits as compared to the Edward's Kits showed that the Sentra Kit served the same functions with the same degree of safety as the Edward's Kits.
## Design
Specifications for components and packaging including materials used, functions required were developed. Kits were built and sterilized with production intent methods and processes. These kits were then used for functional and predicate device comparison testing.
Sentra has utilized Failure Modes and Effects Analysis to estimate and mitigate risks.
Materials for the kits components were chosen with careful analysis of material properties. Detailed material properties, and the list of materials used are discussed in the Sentra's 510(k) sections and exhibits.
Drawings of the components, assembly have been provided in the 510(k).

Sentra will market standard variants of the base design. The variation is only in the presence or absence of some of the components, variations in lengths of the tubes, while utilizing the same materials and base design verified in testing. A matrix showing these variants is discussed in the 510(k).
#### Testing and verification
The Sentra Kit has passed sterilization tests, bio-compatibility requirements, and product performance standards set forth by Sentra as proven in bench tests. International standards have been adopted in several areas, deemed important. The tests conducted, flow, procedures, acceptance criteria and results are discussed elsewhere in the 510(k).
All tests were designed in a test flow, with detailed test procedures and tests were executed in 2 legs, one was for functional verification of the kits and second for proof of substantial equivalence.
The transducer complies with the industry consensus standard AAMI BP22: 1995 R 2001 tested by our transducer supplier. Results are provided in the 510(k) Exhibit 1.
Detailed discussion and results on all of these topics are available in Sentra's 510(k) sections and exhibits.

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.
