#### F. Purpose of Submission
This submission requests the addition of the Baha 5 Power Sound Processor to the series of sound processors offered by Cochlear Bone Anchored Solutions (CBAS). The Baha 5 Power Sound Processor functions by combining the external sound processor with an abutment (the Connect system) or with a magnet (the Attract system) and small titanium implant that is placed in the skull behind the ear during a simple surgical procedure. The sound processor transmits acoustic signals into electrical signals which then causes mechanical action in the transducer to transmit sound transcranially to the functioning auditory system.
The subject of this Special 510(k): Device Modification is a modification to the Cochlear™ Baha® BP110 sound processor, which was cleared under 510(k) K110996 on May 10th, 2011 for unilateral or bilateral use with conductive and mixed hearing losses, or for single-sided deafness (SSD). The modified device will have the same indication as the primary predicate device. The secondary predicate is the Baha 5 Sound Processor, cleared under 510(k) K142907 on 3/25/2015. The Baha 5 Sound Processor is also cleared for unilateral use with conductive and mixed hearing losses, or for single-sided deafness (SSD). The secondary predicate device shares many features with the proposed modified device. and is included to allow comparison of those features. The subject of this submission, the modified sound processor, will be called the Baha 5 Power Sound Processor.
#### G. Device Description
The technology base for the Baha implant was originally derived from the 1952 discovery by Dr. Per-Ingvar Brånemark that titanium was biocompatible with bone, leading to the term "osseointegration". The Branemark System, as it would later be known, formed the basis for the rapid development and widespread implementation of root form endosseous dental implants. now safely and effectively used by many hundreds of thousands of people worldwide. Root form dental implants share many characteristics with the Baha implant component including material. conformation, and surgical implantation procedures.
Unlike hearing aids, the Baha hearing system utilizes a natural bone conduction pathway to send sound directly to a cochlea with residual functionality. The Baha system combines an external sound processor, in this application the Baha Power Sound processor, with small titanium implant placed into the bone through a simple surgical procedure. The implant is either attached to the sound processor via an abutment or internal titanium-encased magnet paired with an external magnet. The implant subsequently forms an osseointegrated bond with the surrounding bone, allowing transmission of high-quality sound directly to the inner ear, bypassing a damaged
{5}------------------------------------------------
outer or middle ear. The Baha system provides an alternate pathway for patients who may not benefit from wearing an air-conduction hearing aid.
The changes introduced in this 510(k) are specific only to the sound processor. There are no changes to the abutment/implant or magnet.
The modified sound processor, the Baha 5 Power Sound Processor is an upgrade to the currently marketed BP110 Sound Processor (which it will replace on the US market) and the Baha 5 Sound Processor. The Baha 5 Power Sound Processor provides gain sufficient to match the Indications for Use of the currently marketed BP110 Sound Processor. As the modified device utilizes the same fundamental scientific principles, the same intended use and indications for use as the current legally marketed primary predicate device it will replace, and merely represents improvements in features that are the same as those used in another Cochlear Baha sound processor that has already been cleared for marketing for a less hearing-impaired population (the model Baha 5 Sound Processor, cleared under K142907), we believe these modifications are appropriate for the Special 510(k) process.
The Baha 5 Power Sound Processor does not modify the intended functionality or fundamental operating principles of the implant/abutment system.
#### H. Intended Use
The new Baha 5 Power Sound Processor will be used as an external sound processor option (in the Cochlear Baha family of sound processors) to conduct sound energy directly to the cochlea via a Baha auditory osseointegrated implant, or via transcutaneous transmission with a Baha headband or Softband.
This is the same intended use as the current legally marketed, unmodified BP110 Sound Processor (the primary predicate device that it will replace) and the Baha 5 Sound Processor (the secondary predicate).
#### I. Indications for Use
The Cochlear Baha® 5 Power Sound Processor is intended for the following patients and indications for use:
- . Patient of any age for use with the Baha Softband or headband. Patients aged 5 and older for use with the Baha auditory osseointegrated implant system.
- . Patients who have a conductive or mixed hearing loss and can still benefit from sound amplification. The pure tone average bone-conduction hearing threshold (measured at 0.5, 1, 2, and 3kHz) should be better than or equal to 55 dB HL.
- . Bilateral fitting is intended for patients who meet the above criterion in both ears, with bilaterally symmetric moderate to severe conductive or mixed hearing loss. Symmetrical bone-conduction thresholds are defined as less than a 10 dB average difference between ears (measured at 0.5, 1, 2, and 3 kHz), or less than a 15 dB difference at individual frequencies.
- Patients who suffer from unilateral sensorineural deafness in one ear with normal hearing . in the other ear (i.e. Single-sided deadness: SSD). Normal hearing is defined as a pure
{6}------------------------------------------------
tone average air-conduction hearing threshold (measured at 0.5, 1. 2. and 3 kHz) of better than or equal to 20 dB HL.
- Baha for SSD is also indicated for any patient who is indicated for an air-conduction ● contralateral routing of signals (AC CROS) hearing aid, but who for some reason cannot or will not use an AC CROS.
### J. Technological Characteristics
The Baha 5 Power Sound Processor has the same intended use, the same mechanical design, the same functional characteristics, the same fundamental operating principles, and is made of biocompatible materials like the predicate devices.
The modified sound processor will still be compatible with the currently marketed Softband/headband (cleared under K002913 and letters to file under this clearance), and the currently marketed auditory osseointegrated implants (BIA300 system, cleared under K100360 and BA400 cleared under K121317 as well as the Baha Attract cleared under K131240), and will also be backward compatible with the original auditory osseointegrated implant (cleared under K955713).
#### K. Materials
The Baha 5 Power Sound Processor is made of medical grade plastics and metals that have been shown to be biocompatible and safe for human use.
#### L. Performance Data
Bench testing was conducted to compare the Cochlear Baha® 5 Power Sound Processor with the predicate implant / abutment systems. Substantial equivalence to the predicate devices was accomplished through environmental testing, reliability testing, electrical interface testing, and functional testing. The results demonstrated the Cochlear Baha 5 Power Sound Processor is functionally equivalent to the predicate devices.
#### M. Conclusion
Based on the indications for use, technological characteristics, and substantial equivalence comparison to the predicate devices, the Baha 5 Power Sound Processor has been shown to be safe and effective for its intended use.

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.
