Indications for Use
The MITEK TIGHT-N™ Tendon Docking Anchor is indicated for use for reattachment of soft tissue to bone for the following procedures: Shoulder: Biceps tenodesis Knee: Medial patellofemoral ligament repair/reconstruction (MPFL), posterior oblique ligament repair (POL), medial collateral ligament (MCL) repair, lateral ligament (LCL) repair, anterolateral ligament (ALL) reconstruction, Iliotibial (IT) Band Tenodesis
Device Story
The MITEK TIGHT-N™ Tendon Docking Anchor is a sterile, single-use implant designed for reattaching soft tissue to bone. It is provided preloaded on a disposable inserter shaft with a handle, secured by a stay suture. The device is available in 5.5 mm, 7.0 mm, and 8.5 mm sizes. During surgery, the surgeon threads the suture tails of a pre-stitched soft tissue graft through the anchor; the anchor is then inserted into the bone to secure the graft. Used in orthopedic surgical settings, the device provides mechanical fixation to facilitate tissue healing. It benefits patients by restoring soft tissue-to-bone attachment in ligament and tendon repair procedures.
Clinical Evidence
Bench testing only. Verification activities included biocompatibility, shelf-life, pyrogenicity, and endotoxin testing. Performance testing assessed fixation strength and fatigue strength. Sterilization validated per ANSI/AAMI/ISO 11135:2014; EO residuals tested per AAMI/ANSI/ISO 10993-7:2008; non-pyrogenicity confirmed per ANSI/AAMI ST-72:2011.
Technological Characteristics
Material: PEEK (Polyetheretherketone). Design: Suspensory push-in anchor. Sizes: 5.5 mm, 7.0 mm, 8.5 mm. Sterilization: Ethylene Oxide (EO) per ANSI/AAMI/ISO 11135:2014. Single-use. No software or electronic components.
Indications for Use
Indicated for reattachment of soft tissue to bone in shoulder (biceps tenodesis) and knee (MPFL, POL, MCL, LCL, ALL reconstruction, IT Band tenodesis) procedures.
Regulatory Classification
Identification
A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

| Substantial<br>Equivalence | The MITEK TIGHT-NT™ Tendon Docking Anchor is substantially<br>equivalent to:<br>• K201749 Arthrex Biocomposite 3.9mm SwiveLock Anchor | |
| Device<br>Classification | The MITEK TIGHT-NTM Tendon Docking Anchor is classified as:<br>Fastener, Fixation, Nondegradable, Soft Tissue, classified as Class II,<br>product code MBI, regulated under 21 CFR 888.3040. | |
| Device Panel | Orthopedic Devices | |
| Device<br>Description | The MITEK TIGHT-NTM Tendon Docking Anchor is designed to<br>reattach soft tissue to bone when used in conjunction with suture<br>(provided separately). The anchor is preloaded on a disposable inserter<br>shaft with handle, held in place by a non-absorbable "stay suture". The<br>proposed anchor will be offered in three sizes: 5.5 mm, 7.0 mm, and 8.5<br>mm and is molded from PEEK (Polyetheretherketone) material. The<br>proposed anchor is provided sterile via Ethylene Oxide (EO)<br>sterilization and is for single use only. | |
| Technological<br>Characteristics | The anchor design, principal of operation and intended use on MITEK<br>TIGHT-NTM Tendon Docking Anchor are similar when compared to the<br>predicate Arthrex 3.9mm SwiveLock Anchor (K201749). Both devices<br>are implantable anchors used to secure soft tissue to bone. Suture tails<br>of a pre-stitched soft tissue graft (suture provided separately) are<br>threaded through the anchors, thus securing the graft to the anchor.<br><br>The proposed MITEK TIGHT-NTM Tendon Docking Anchor is<br>designed as a suspensory push-in anchor, while the predicate<br>SwiveLock is designed as an interference thread-in anchor. While there<br>exists differences in the means of insertion style (thread-in vs. push in)<br>and mechanism of tissue retention, the proposed and predicate devices<br>are ultimately securing soft tissue to bone to achieve the device's<br>therapeutic benefit.<br><br>Both predicate and proposed devices are provided with sutures<br>facilitating placement of the anchor (stay sutures for both the proposed<br>and the predicate device and an additional axillary suture for the<br>proposed MITEK TIGHT-NTM Tendon Docking Anchor).<br><br>The proposed anchor is constructed from PEEK material, the predicate<br>Arthrex SwiveLock is composed of both PEEK and PLLA/βTCP<br>materials. The PEEK material, of the proposed anchor implant, is<br>identical to the PEEK material of existing Mitek implantable anchors –<br>Versalok Anchors (K100532)<br><br>Any differences between the proposed device and the predicate are<br>considered non-significant and do not raise different questions of safety<br>or effectiveness, supported by testing. | |
| Indications for<br>Use | The MITEK TIGHT-NTM Tendon Docking Anchor is indicated for use<br>for reattachment of soft tissue to bone for the following procedures:<br>Shoulder: Biceps tenodesis Knee: Medial patellofemoral ligament repair/reconstruction<br>(MPFL), posterior oblique ligament repair (POL), medial collateral<br>ligament (MCL) repair, lateral collateral ligament (LCL) repair,<br>anterolateral ligament (ALL) reconstruction, Iliotibial (IT) Band<br>Tenodesis | |
| Non-clinical<br>Testing | Verification activities were performed on the proposed device and / or<br>its predicates. Biocompatibility, shelf-life, pyrogenicity, endotoxin and<br>performance testing conducted on representative products was presented<br>to support determination of equivalence. Performance testing included<br>assessment of fixation strength and fatigue strength. | |
| | Ethylene Oxide Sterilization was validated according to<br>ANSI/AAMI/ISO 11135: 2014 to a SAL of 1 x 10-6. | |
| | EO residuals were tested per AAMI/ANSI/ISO 10993-7:2008 | |
| | The proposed device has been determined to be non-pyrogenic per the<br>requirements set forth in ANSI/AAMI ST-72:2011, United States<br>Pharmacopeia (USP), and European Pharmacopeia (EP) using the<br>bacterial endotoxin testing (BET) method. | |
| Safety and<br>Performance | Results of performance testing have demonstrated that the proposed<br>devices are suitable for their intended use. | |
| | Based on similarities in the intended use, technological characteristics,<br>and performance in comparison to the predicate devices, the proposed<br>MITEK TIGHT-NTM Tendon Docking Anchor has shown to be<br>substantially equivalent to the predicate device under the Federal Food,<br>Drug and Cosmetic Act. | |

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.
