# Description of Device
The PharmaJet, Inc. PharmaJet Needle-free Injector System (PharmaJet System) is a compact, spring-loaded needle-free hypodermic injector system. The PharmaJet System consists of two (2) injectors (One is the light injector suitable for infants up to two years old, geriatric adults or locations with thin skin and minimal adipose tissue and one is the heavy injector suitable for adults and children two years and older, or locations with thicker skin and more adipose tissue.), a cocking device, a single use, sterile, disposable filling adapter, and a single use, sterile, disposable needle-free svringe.
An iniector is placed in the cocking device and the lid is depressed to cock the spring in the injector. The healthcare worker puts a filling adapter into a vial of liquid medicine or vaccine. A needle-free syringe is placed into the filling adapter and the liquid is drawn into the needle-free syringe and is slightly over filled. The plunger is broken off and discarded. With the adapter, needle-free syringe, and vial still engaged the needle-free syringe is placed into the injector with a ¼ turn to the right, this returns excess medicine or vaccine back into the vial and positions the plunger to deliver a 0.5ml dose. The adapter and filled needle-free syringe can now be separated. The needle-free syringe is placed against the injection site, which displaces the safety interlock. By depressing the trigger the spring is released and the plunger moves forward into the needle-free syringe barrel discharging the contents. As the medicine or vaccine passes through the orifice under high pressure, it forms a jet of fluid that penetrates the skin.
# Iniector
The Injector is a reusable compact spring-actuated needle-free hypodermic injector consisting of the body, inner body/safety collar, trigger, and spring. The injector is made with stainless steel and injection molded amorphous thermoplastic polyetherimide.

# Needle-free Syringe
The Needle-free syringe is a single use, transparent, disposable, polypropylene container consisting of the barrel to hold 0.5ml of medicine or vaccine, a plunger to discharge the medicine or vaccine through a small diameter orifice at the forward end of the barrel, and a silicone seal on the plunger to prevent leakage of the medicine or vaccine rearward.
### Cocking Device
The cocking device is used to prepare (cock) the spring, within the injector, for injection. The cocking device is made with stainless steel and injection molded amorphous thermoplastic polvetherimide.
#### Filling Adapter
The filling adapter allows the needle-free syringe to be filled with medicine or vaccine from medicine or vaccine storage vials.
The filling adapter material, which does not contact the patient, is injection-molded polycarbonate.
## Intended Use
The PharmaJet Needle-free Injection System is intended to deliver various medications and vaccines either intramuscularly or subcutaneously by means of a narrow, high velocity fluid jet, which penetrates the skin and delivers the medicine or vaccine to the body. Healthcare providers who routinely administer injections may use the PharmaJet Needle-free Injection System. It may be used for adults and children. It can also be used by patients authorized by their physicians to self inject, or have other individuals administer injections of prescribed medication.

# Discussion of the Non-clinical Tests
Pigs have been determined to be predictive models for depth of penetration studies for healthy adults and children two years and older, or locations with thicker skin and more adipose tissue for injection into the deltoid, lateral thigh, or buttocks. Lambs have been determined to be predictive models for depth of penetration studies in infants up to two years old, geriatric adults or locations with thin skin and minimal adipose tissue. Preclinical animal testing using these two animal models have been completed for intramuscular and subcutaneous delivery to demonstrate substantial equivalence to a predicate device. It was found in these tests that the variability in the PharmaJet Injector's depth of penetration is equal to or less than the variability of the Bioject B2000 iniector's depth of penetration. Overall there is no difference in accuracy of the two injectors and for subcutaneous injections the PharmaJet injector is more accurate than the Bioject injector.
Bench testing has been completed to establish that the system meets customer requirements for performance and robustness by meeting the essential requirements of ISO21649:2006 Needle-free iniectors for medical use -Requirements and test methods. These include operating temperature, storage temperature, free-fall, vibration, shock, dose accuracy, life cycle, performance profile upper and lower acceptance limits, and emitted noise.
Maximum irradiated sterility dose test was done on the needle-free syringe to demonstrate material robustness, and microbial ingress testing on the Filling Adapter was done to demonstrate that the Filling Adapter can be disinfected using common disinfection techniques.
Biocompatibility testing conducted demonstrate that the PharmaJet Needle-free Syringe and Filling Adapter meet the requirements for safe short-term exposure.

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.
