Device Story
AR1000 Ultrasonic Wound Therapy System uses low-frequency (35kHz) ultrasonic energy to promote wound healing. System comprises a generator, handheld converter, and distal probe (Qurette). Generator converts wall power to ultrasonic signal; converter transforms signal into mechanical displacement at probe tip. Energy applied via direct contact or non-contact techniques, often coupled with liquid medium (e.g., sterile saline) to lavage wound bed. Used in hospital, clinic, home, or intra-operative settings by clinicians. Ultrasonic energy facilitates selective/non-selective tissue dissection, fragmentation, and debridement of necrotic tissue, slough, eschar, and bacteria. Cleansing irrigation removes debris and exudates. Clinicians use device to prepare wound beds for grafts or subsequent procedures. Benefits include efficient removal of nonviable tissue and wound bed preparation, potentially accelerating healing. Device is prescription-only.

#### Device Description
The AR1000 Ultrasonic Wound Therapy System and its variants use ultrasonic energy from a generator delivered by a conductive cable to a hand held converter through the converter's distal end probe and liquid coupling medium: to perform wound therapy; to perform ultrasonic surgical, excisional, and or sharp-edge selective dissection procedures; with the intended end result to promote healing.
The AR1000 Ultrasonic Wound Therapy System generator utilizes commonly available wall outlet power (85 -260VAC, 50/60Hz) to produce the ultrasonic signal. A conductive cable connects the generator to the hand held converter. The hand held converter converts the signal into ultrasonic mechanical displacement in the distal end probe or Qurette. The ultrasonic mechanical displacement energy is applied to the treatment site by the distal end probe or Qurette through direct contact or noncontact techniques. The ultrasonic mechanical displacement energy is also transmitted as ultrasonic energy to the treatment site via the liquid coupling medium.
The AR1000 Ultrasonic Wound Therapy System distal end probe or Qurette is used with contact or non-contact modes to achieve intended wound therapy modalities to promote wound healing. This is achieved through the use of the low-frequency, controlled-intensity, ultrasonic energy to perform ultrasonic dissection and fragmentation of tissues, debridement of wound tissue (acute and chronic wounds, burns, diseased or necrotic tissue), and surgical, excisional or sharp-edge incisions.
The AR1000 Ultrasonic Wound Therapy System distal end probe or Qurette is used with contact or non-contact modes to achieve wound therapy and promotes wound healing through the ultrasonic dissection and fragmentation of tissues, debridement of wound tissue (acute and chronic wounds, burns, diseased or necrotic tissue) through the use of the low-frequency, controlled-intensity, non-thermal ultrasonic energy.
The AR1000 Ultrasonic Wound Therapy System ultrasonic energy, via the liquid coupling medium to the treatment site, promotes wound healing through the lavage of wound tissue (acute and chronic wounds, burns, diseased or necrotic tissue) and cleansing irrigation of the site for the removal of debris, exudates, fragments, bacteria, and other matter.
The AR1000 Ultrasonic Wound Therapy System uses continuous ultrasonic energy to propel the liquid medium (e.g. sterile saline, or other appropriate US FDA cleared medium) into a solution stream and couples the delivery of ultrasonic energy to the treatment site. This is accomplished by the ultrasonic energy application to the

#### 807.92(b)
#### Safety and Effectiveness
There have been no changes to the AR1000 Ultrasonic Wound Therapy System cleared under 510(k) K062544 as a result of the proposed labeling changes.
This 510(k) submission supports an expansion of the device's Indications For Use. with respect to K062544, to incorporate expanded patient results and laboratory findings.
The expansion of the device's Indications For Use, with respect to K062544, do not raise any new issues of safety or effectiveness.
For safety and effectiveness purposes the AR1000 Ultrasound Wound Therapy System and its variants is substantially equivalent to the previously cleared AR1000 Ultrasound Wound Therapy System (K062544), the Misonix SonicOne (K112782) system, Celleration MIST (K122246) system, the Soring Sonoca (K072904) systems, and the Ethicon (K002906) system.
#### 1.0 Efficacy
This device, like the predicates, is directed for single (1) treatment, and total recommended treatments shall be no more than three (3) times per week or as directed on the order of the physician. A typical treatment regimen is approximately two (2) weeks or more, depending on the size and nature and or condition of the treated area as well as other subject dependent factors, but may be prescribed for more or less frequent use and or for shorter or longer treatment regimen durations on the order of a physician.
This device also compares with the predicates, as follows:
1.1. Controlled ultrasonic delivery with 0.9% sterile saline solution, or other approved medium, to lavage the wound tissue (e.g. acute and chronic wounds, burns, diseased or necrotic tissue), like the Arobella AR1000 (K062544) system and the Celleration (K122246) predicate ultrasonic wound system.
1.2. Maintenance debridement of the treatment site for the removal of loose fragments, debris, exudate, bacteria, and other matter, like Arobella AR1000 (K062544) system, the Misonix SonicOne (K112782) system, the Celleration (K122246) system, and the Soring Sonoca (K072904) predicate ultrasonic wound system.
Section 005 510(k) Summary
Page 005-11 of 005-13
{11}------------------------------------------------
1.3. Ultrasonic selective dissection and debridement of tissue through the use of the probe (aka Qurette), including parallel to the wound bed surface for shallow separation of tissue lavers, like the predicate Arobella AR1000 (K062544) system and the Misonix SonicOne (K112782) system.
#### 2.0 Safety
The AR1000 Ultrasonic Wound Therapy System and its variants consists of an ultrasonic power supply (hereto after referred to as a generator), an ultrasonic converter hand piece (or just converter), and distal end probe tip (Qurette), a liquid supply reservoir and delivery tubing. Substantial equivalence has been previously established between the AR1000 Ultrasonic Wound Therapy System (K062544) and the Celleration Mist, and the Misonix SonicOne predicate ultrasonic wound cleanser devices as outlined under K062544.
#### 2.1 Electrical Safety & Electromagnetic Compatibility
Similar to the relevant predicates, this device complies with the following standards:
· IEC 60601-1 Medical electrical equipment, Part 1: General requirements for basic safety and essential performance
· UL 60601-1 Medical Electrical Equipment, Part 1: General Requirements for Safety
• IEC 60601-1-2 Medical electrical equipment, Part 1-2: Electromagnetic compatibility
- Requirements and tests
· IEC 60601-1-4 Medical electrical equipment, Part 1-4: Programmable electrical medical svstems
· FCC Part 18 - EMC Requirements
#### 2.2 Ultrasonic Safety
Similar to the relevant predicates, this device complies with the following standards:
- · 21 CFR 1050.10 Ultrasonic therapy products
- · IEC 61847 Ultrasonics Surgical systems Measurement and declaration of the basic output characteristics
Section 005 510(k) Summary
{12}------------------------------------------------
#### 2.3 Biocompatibility
Similar to the relevant predicates, this device was tested for and complies with the standard ISO 10993-1:2003 - Biological evaluation of medical devices, Part 1: Evaluation and testing and its relevant annexes (based on nature and duration of patient contact). All testing was conducted in compliance to 21 CFR. Part 58 Good Laboratory Practice for Nonclinical Laboratory Studies.
The AR1000 system is routinely used with 0.9% sterile saline solution, which is widely available for purchase from medical suppliers in bottle or bag form and is to be supplied by the user, as well as the tubing and the valve (for saline flow control). In the alternate, the AR1000 can also be used with other appropriate sterile mediums and US FDA-approved irrigation liquids. This is substantially equivalent to all of the predicate devices and irrigation solutions.
#### 2.4 Transportation/Storage
Packaging systems for the non-sterile device and for the non-sterile accessories of the device (e.g. the converter, tips, shroud, et al) keep the product without deterioration and without a specific level of sterility stipulated, as do the predicate devices. Those accessories used specifically for treatment (e.g. converter, tip, shroud, etc) are to be sterilized prior to use to minimize the risk of microbial contamination, as established with the AR1000 K062544 device clearance.
As the device and the accessories are durable goods with little or no notable deterioration, the shelf life is the product lifecycle, barring storage or transportation damage, and/or use under extremes of environmental conditions (e.g. temperature, humidity, moisture, etc).
#### 2.5 Reprocessing
The AR1000 system, as well as the AR1000 ultrasonic converter hand piece, is the wound debridement device cleared under K062544 for which reprocessing instructions have been previously validated and cleared.
The variant AR1000 ultrasonic converter hand piece allows for steam sterilization (autoclave) in addition to the previously cleared and validated reprocessing methodology. This variant may therefore be reprocessed by steam sterilization (autoclave), as well as the previously cleared and validated reprocessing methodology.

Dear Mr. Berscheid:
We have reviewed vour Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
