Indications for Use
Assistance in the delivery of local anaesthetic after hamstring harvest during ligament reconstruction procedures.
Device Story
GRAFTSITE is a catheter-based device used to deliver local anesthetic bolus injections into the femoral gutter following hamstring harvest during ligament reconstruction. The device consists of a 28.25 cm catheter (4.0 mm OD, 2.6 mm ID) with lateral eyes at the patient end, a rounded/blocked tip, and a 6% female luer hub. A rigid stainless steel buttoned stylet is inserted into the lumen to provide stiffness during placement. The device is used by clinicians in a surgical setting. Unlike nerve-stimulating needles, GRAFTSITE does not require tissue puncture or electrical nerve localization; it is inserted through the existing surgical access site. By delivering anesthetic directly to nerve endings within and surrounding the femoral gutter, the device provides regional anesthesia, potentially reducing post-operative pain for the patient.
Clinical Evidence
No clinical data was required to establish substantial equivalence. Evidence consists of bench testing (pressure, tensile, flow, radio-opacity, corrosion) and a cadaveric usability investigation.
Technological Characteristics
Catheter length 28.25 cm, 4.0 mm OD, 2.6 mm ID. Materials: stainless steel stylet, catheter with lateral eyes. Connectivity: 6% female luer hub (ISO 594-2). Sterilization: Gamma irradiation (VDmax25, SAL 10^-6). Standards: EN 1618, ISO 594-1/2, BS 6196, ASTM F640-12, ISO 10993-1 (biocompatibility).
Indications for Use
Indicated for patients undergoing hamstring ligament reconstruction procedures to assist in the delivery of local anesthetic after hamstring harvest.
Regulatory Classification
Identification

| Classification | Classification - II<br>Product Code - BSP<br>Classification name – Anesthesia conduction needle<br>Classification Rule - 868.5150<br>Device Panel – 73 - “Anesthesiology” |
| Predicate device(s) | Pajunk® “Unipolar Needles”, initially cleared under K000722 and<br>subsequently cleared under part of Special 510(k) K053283<br>(under new trade name UniPlex NanoLine cannula). |
| Indications for use | GRAFTSITE Indications for Use Statement - "Assistance in the<br>delivery of local anaesthetic after hamstring harvest during<br>ligament reconstruction procedures."<br><br>The Indications for Use statement of GRAFTSITE is different to<br>that of the predicate device - "The PAJUNK needles are used to<br>puncture the tissue in order to gain entry and locally inject<br>anesthetics to induce regional anesthesia. An electrical stimulus<br>may be applied to the needle via a cable and connector to assist<br>the physician pinpoint the area of application." due to<br>GRAFTSITE having a more limited depiction of use compared to<br>that of the predicate.<br><br>GRAFTSITE has a catheter round and blocked at the patient end<br>as is not required to puncture tissue to gain entry, due to the |
| | |
| | method of access being through the already present femoral<br>gutter, compared to the predicate that requires a puncturing tip<br>at the end of the cannula in order to pierce the skin for nerve<br>access. Therefore, this difference does not raise different<br>questions of safety and effectiveness. |
| | GRAFTSITE is used for inducing regional anesthesia by<br>assisting in the injection of anesthetics like the predicate, it just<br>has a more limited depiction of use to only after hamstring<br>harvest during ligament reconstruction procedures. In<br>subsequent clearance K053283 it states that PAJUNK Unipolar<br>needles (initially cleared under K000722) are marketed as single<br>shot needles under the trade name UniPlex and that the<br>anesthesia conduction catheter allows for bolus injections or<br>continuous infusion of local anesthetics. This shows the<br>predicate can be used for the same intended purpose as<br>GRAFTSITE, assisting in delivery of a bolus of anesthetic,<br>therefore this does not raise different questions of safety or<br>effectiveness. |
| | GRAFTSITE does not require the physician to pinpoint the area<br>of application via electrical stimulus, as it fulfils its intended use<br>through localization of anesthetic directly to nerve endings<br>within, and surrounding, the comorbidities at the already femoral<br>gutter, compared to the predicate which utilizes nerve stimulation<br>to localize the more proximal nerve sheath. Therefore, this<br>difference does not raise different questions of safety and<br>effectiveness. |
| Device description | GRAFTSITE is 28.25 cm in length with an inner diameter of 2.6<br>mm and an outer diameter of 4.0 mm, sized to fit down the<br>hamstring harvest site. It is rounded and blocked at the patient<br>end and has a 6% female luer at the user end. There are lateral<br>eyes over a length at the patient end of the catheter. A buttoned<br>stylet consisting of a rigid stainless steel rod of diameter slightly<br>less than the bore of the catheter, functions to stiffen the device.<br>GRAFTSITE can be used to directly administer a bolus of the<br>users chosen local anesthetic, via injection down the lumen of<br>the catheter, into the terminus of the gutter at the site of<br>comorbidity. |
| Non-clinical testing | Based on the characteristics identified as relevant from<br>performance standards, GRAFTSITE was directly compared to<br>the predicate in comparative performance tests. |
| | Testing performed in order to verify substantial equivalence<br>included: |
{4}------------------------------------------------
{5}------------------------------------------------
Pressure testing of the catheter/hub for resistance to ● liquid leakage (in accordance with EN 1618 and ISO 594-2) Tensile bond performance of the catheter/hub and . stylet/button (in accordance with BS 6196 and EN 1618) Corrosion resistance of the stylet (as per EN 1618) ● . Flow rate of the catheter (in accordance with EN 1618) Radio-opacity of the catheter (in accordance with ASTM ● F640-12) Human factors/usability validation of the device ● GRAFTSITE performed equally well in all performed tests necessary to demonstrate that it is substantially equivalent to the predicate. The catheter luer hub is manufactured in accordance with EN1707/ISO 594-2 and BS EN 20594-1/ISO 594-1. Further testing specific to ISO 594-1/ISO 594-2 was not required due to the following; Gauging testing - no axial force applied during intended ● use . Air leakage during aspiration - no aspiration during intended use . Separation force - no axial force applied during intended use . Stress cracking - limited stress applied during intended duration of use (≤1 minute) Unscrewing torque - no unscrewing torque applied during . intended use Ease of assembly - no axial or rotational force applied . during intended use . Resistance to overriding - no torque applied during intended use In addition, the requirement for a compliant 6% luer syringe, in accordance with ISO 594-2, to be used in conjunction with the device is indicated to users in the IFU. Biocompatibility testing on the fully finished device demonstrated that GRAFTSITE is biocompatible in relation to its intended use in accordance with ISO 10993-1 and the FDA guidance document on that standard, and is therefore determined to be
{6}------------------------------------------------
| | biocompatible within a risk management process. This test<br>process included cytotoxicity, sensitization, irritation/<br>intracutaneous reactivity, acute systemic toxicity, material-<br>mediated pyrogenicity, particulate analysis, hemolysis, and<br>endotoxin testing. |
|----------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | Gamma irradiation validation using the VDmax25 method, in<br>accordance with ISO 11137-1 and ISO 11137-2, was successful<br>in eliciting no growth for a routine processing dose of 25-40kGy<br>and giving a SAL of 10-6 (in accordance with EN 556). |
| Clinical testing | Clinical data was not required to establish substantial<br>equivalence between GRAFTSITE and the predicate device. |
| Physical differences | Both GRAFTSITE and the predicate are constructed of<br>established, clinically used materials, with confirmatory<br>biocompatibility testing verifying this. |
| | The catheter being rounded and blocked at the patient end is<br>due to the method of access being through the already present<br>femoral gutter, compared to the predicate that requires a<br>puncturing tip at the end of the cannula in order to pierce the<br>skin to access the femoral nerve. |
| | The length of the catheter is significantly longer due to the<br>requirement for placement at the terminus of the proximal<br>femoral gutter compared to the predicate, which typically only<br>requires access 2 – 3cm below the skin. |
| | The stainless steel stylet assembly of GRAFTSITE provides<br>rigidity to the catheter upon insertion compared to the predicate<br>which has a rigid stainless steel cannula for insertion |
| | The presence of a stimulator cable with the predicate is due to<br>the indications for use (i.e. for the localization of peripheral nerve<br>bundles through nerve stimulation). GRAFTSITE is not indicated<br>for peripheral nerve stimulation. |
| | Comparative in vitro testing was performed, with the results for<br>GRAFTSITE compared to the predicate, which showed that<br>there were no different questions of safety and effectiveness<br>raised. |
| Handling<br>differences | Whilst the predicate is of a clinically standard technique,<br>GRAFTSITE was proven to be usable in a cadaveric usability<br>investigation, and did not raise different questions of safety and<br>effectiveness when compared to the predicate |
| Chemical<br>differences | Both GRAFTSITE and the predicate are constructed of<br>established, clinically used materials, with confirmatory<br>biocompatibility testing verifying this. Comparative in vitro testing<br>was performed, with the results for GRAFTSITE compared to the<br>predicate. |
| Substantial<br>equivalence | Based on the similarities in design, function, indications for use<br>and fundamental scientific technology, the subject devices of this<br>submission is similar to the predicate device and does not raise<br>different questions of safety and effectiveness. Therefore,<br>Summit Medical concludes that the subject device, GRAFTSITE,<br>is substantially equivalent to the predicate device. |

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.
