## D. DEVICE DESCRIPTION
The BC Reflex Uni™ Knee System is a patient-specific unicompartmental knee system that consists of femoral and tibial implants for replacement of the medial tibiofemoral compartment of the knee. The patient-specific femoral and tibial implants and single-use instruments are manufactured from CAD and CAM files generated from Bodycad software that are based on MRI or CT images of the patient's knee and surgeon input.
The main purpose of this traditional 510(k) Notification is to advise the FDA of Bodycad's use of low temperature hydrogen peroxide sterilization (VH2O2) for terminal sterilization of BC Reflex Uni patient kits. Secondary purposes of this 510(k) notification are validation of cleaning and steam sterilization of BC Reflex Uni Knee System components in case of breach of sterile packaging in transit or handling, and minor design updates to single use instrumentation and software. BC Reflex Uni components are supplied sterile (SAL of 10-6 via gamma radiation or VH2O2).
Materials: Femoral component: ASTM F1537-11 wrought CoCrMo. Tibial baseplate and locking pin: ASTM F136 titanium alloy (ELI). Tibial insert: F648-14 UHMWPE.
## E. INTENDED USE
The patient-specific BC Reflex Uni is indicated for unicompartmental knee arthroplasty (UKA) in patients with advanced knee osteoarthritis (OA) of the medial compartment with evidence of adequate healthy bone to support the implanted components. Candidates for unicompartmental knee replacement include those with:
- joint impairment due to osteoarthritis or traumatic arthritis of the knee,
- varus deformity of the knee, and
- as an alternative to tibial osteotomy in patients with unicompartmental OA.
The patient-specific BC Reflex Uni components fit within an envelope of dimensions that are specific to each patient. The BC Reflex Uni femoral component and tibial baseplate are intended for cemented fixation.
## F. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The BC Reflex Uni Knee System described in this 510(k) notification is essentially the same as the primary predicate device cleared by FDA in K203697. Commonalities shared by both the subject and primary predicate devices include:
- Patient specific knee implants and instruments designed and manufactured from MRI or CT images of the patient's knee.
- · Patient specific components including CoCr femoral and Ti allov locking pin and tibial baseplate, polyethylene inserts, and single use Nylon-12 bone models and guides.
- · The clinical indications for use and intended use are identical.
- · The CoCrMo, titanium alloy, UHWMPE, and Nylon-12 materials are identical.
- · The manufacturing processes are identical.
- · Single use, patient specific kit provided sterile with SAL of 10-6.
{5}------------------------------------------------
The differences between the subject and primary predicate devices are:
- Addition of a second option for terminal sterilization of BC Reflex Uni patient kits using low temperature vapor hydrogen peroxide sterilization (VH2O2) using the STERIS V-PRO maX (K102330).
- · Addition of ability to perform one-time, point of use cleaning and steam sterilization of BC Reflex Uni components in case of breach of sterile packaging in transit or handling.
- Two minor updates to the single use instruments and two minor updates to the software to better facilitate surgical procedure and patient specific design.
# G. PERFORMANCE DATA
The followinq verification and validation (V&V) activities were performed:
- . Validation of terminal sterilization with SAL of 10-6 for worst-case BC Reflex Uni kits using the STERIS V-PRO maX (K102330) per the applicable clauses of ISO 14937.
- Validations of shelf life, biocompatibility per ISO 10993-1, packaging per AAMI/ANSI/ISO . 11607, and verification of acceptable levels of residual hydrogen peroxide per ISO 10993-17.
- . Validation that BC Reflex Uni components meets pyrogen limit specifications (e.g., bacterial endotoxins test (BET), also known as the Limulus amebocyte lysate (LAL) test).
- . Validation of point of use cleaning and steam sterilization applicable to BC Reflex Uni components using the partial cycle validation approach outlined in ANSI/AAMI/ISO 17665-1:2006/(R)2013, Annex D, and the validation approach outlined in ANSI/AAMI/ISO 14937:2009/(R)2013, Annex D (Approach 3).
The results of V&V testing and engineering review, risk analysis, and design control activities demonstrated no new issues affecting safety or effectiveness resulting from the new methods of cleaning and sterilization of the BC Reflex Uni Knee System and the two minor updates to the single use instruments and update to software.
# H. CONCLUSION
The results of V&V testing and engineering review, risk analysis, and design control activities demonstrated substantial equivalence of the subject BC Reflex Uni Knee System sterilized by low temperature hydrogen peroxide vapor to the primary predicate device, the BC Reflex Uni Knee System sterilized by gamma radiation.

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.
