The Aveir Retrieval Catheter is intended to be used in the peripheral vasculature and the cardiovascular system to retrieve and manipulate an Abbott Medical leadless pacemaker (LP). Retrieval and manipulation includes removing the LP from the heart or peripheral vasculature.
Device Story
The Aveir Retrieval Catheter is a single-use, sterile, steerable catheter system designed for the retrieval of leadless pacemakers (LP). It consists of a valve bypass tool, a steerable/deflectable catheter, an integrated guiding catheter with a protective sleeve, and a tri-loop snare. Operated by a physician in a clinical setting, the device is advanced through the femoral vein using minimally invasive techniques under fluoroscopic guidance. The operator steers the catheter to the LP, snares the docking button, docks the catheter to the LP, and rotates the device to unscrew the LP helix from the endocardium. The protective sleeve shields the helix and electrode during extraction through the vasculature. This device enables the removal of previously implanted leadless pacemakers, providing a safe method for device retrieval and potentially reducing risks associated with leaving non-functional implants in situ.
Clinical Evidence
No clinical data. Evidence consists of bench testing and animal studies. Bench testing included biocompatibility (ISO 10993-1), physical/dimensional characteristics, tensile/torsional strength, deflection, simulated use, and packaging/shelf-life. A 182-day chronic GLP ovine study demonstrated a 100% retrieval success rate for Aveir Leadless Pacemakers. Pathological evaluation confirmed atraumatic removal with no significant injury to the IVC, right heart, or tricuspid valve. Usability validation confirmed acceptable usability and residual risk.
Technological Characteristics
Single-use, steerable/deflectable catheter system. Components: valve bypass tool, steerable catheter, integrated guiding catheter, tri-loop Nitinol snare. Effective length: 105 cm; snare loop diameter: 16.5 mm. Radiopaque markers for fluoroscopic visibility. Sterilized via ethylene oxide. Materials include Pebax and Nitinol. Operates via manual mechanical manipulation (advancement, retraction, rotation, deflection).
Indications for Use
Indicated for use in the peripheral vasculature and cardiovascular system to retrieve and manipulate Abbott Medical leadless pacemakers (LP) in patients requiring LP removal from the heart or peripheral vasculature.

#### PREDICATE DEVICE IV.
The Aveir™ Retrieval Catheter is substantially equivalent in intended use and method of operation to the predicate devices listed below:
- · 510(k) K092343: Merit Medical, EN Snare® Endovascular Snare System
- 510(k) K122088: Merit Medical, One Snare® Endovascular Snare System
- · 510(k) K133681: Volcano Corporation, Crux® Snare Filter Retrieval Set
#### DEVICE DESCRIPTION V.
The Aveir™ Retrieval Catheter, model LSCR111 comprised of a valve bypass tool, a steerable/deflectable catheter, an integrated guiding catheter with a protective sleeve, and a tri-loop snare, assembled into a single catheter. The tri-loop snare, secured to a shaft, is used to grasp the docking feature on the proximal end of an Abbott Medical Leadless Pacemaker (LP), mate the LP to the Retrieval Catheter, unscrew the LP and retrieve the LP, thereby removing the LP from the patient's heart or peripheral vasculature. The Retrieval Catheter is supplied in a sterile pouch (sterilized via ethylene oxide), is intended for single-use only, and may not be re-sterilized.
This device is an accessory designed to be used with both the Aveir Leadless System and the previous Nanostim Leadless Pacemaker (LP), model number S1DLCP. The Nanostim LP device has not been manufactured or implanted since November 02, 2016. However, the Nanostim LP (model S1DLCP) is currently implanted in patients and in the event these devices need to be retrieved, the Aveir Retrieval Catheter can be used.
The Aveir Retrieval Catheter is intended to be used to retrieve an LP and to be manipulated by a single operator that allows the operator to perform these actions:
- . Advance the Retrieval Catheter from an access site in the groin (utilizing minimally invasive techniques) through the femoral vein into the heart.
- Steer and position the snare towards the docking button of the LP. .
- Snare the docking button of the LP. ●
- Dock the Retrieval Catheter to the LP.
- o Rotate the LP to unscrew the LP helix from the endocardium.
- Protect the LP helix and electrode during retrieval. ●
- Extract the LP through the access site in the groin. o

Image /page/5/Picture/1 description: The image shows the logo for Abbott Laboratories. The logo consists of a stylized letter "A" in blue, positioned above the word "Abbott" in black, sans-serif font. The "A" is designed with rounded corners and a gap in the upper right, giving it a modern and distinctive appearance.
Apart from the docking mechanism, the Retrieval Catheter and its control system (handle) have the same operating principle as a conventional steerable catheter and control system, while the snare mechanism and dimensions are similar to commercially available snares systems. The Retrieval Catheter is intended to be used with the compatible Aveir Introducer.
The Retrieval Catheter effective length is 105 cm (41.3 in) and the snare loop inner diameter is 16.5mm (0.65 in). The technical details and materials used in this product can be found in the Instructions for Use.
#### INDICATIONS FOR USE / INTENDED USE VI.
The Aveir™ Retrieval Catheter is intended to be used in the peripheral vasculature and the cardiovascular system to retrieve and manipulate an Abbott Medical leadless pacemaker (LP). Retrieval and manipulation includes removing the LP from the heart or peripheral vasculature.
The proposed indications for the Aveir Retrieval Catheter are not identical to the predicate devices; however, the differences do not alter the intended therapeutic use of the device relative to the predicates. Both the subject and the predicate devices share the same intended purpose of retrieving and manipulating foreign objects from the cardiovascular system (Primary Predicate Device EN Snare® Endovascular Snare System (K092343)), including the peripheral vascular (ONE Snare™ (K122088) ) and femoral vein (Crux Snare Filter Retrieval Set (K133681)).
### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS VII. WITH THE PREDICATE DEVICE
Retrieving and manipulating foreign objects from the cardiovascular system is the technological principle for both the subject and predicate devices. It is based on manipulation of a snare (opening, closing, rotating) from within an outer catheter. The snare can be positioned near the object and closed to manipulate or retrieve the object.
The subject and predicate devices are based on the following technological elements that are the same:

Below the symbol, the word "Abbott" is written in a bold, sans-serif font in black. The logo is simple, modern, and easily recognizable.
- Single-use devices ●
- Snare introduced via conventional venous access through Pebax catheters ●
- Snare comprised of Nitinol cable loop(s) secured to a shaft
- Radiopaque features on snare and catheter provide physician with visibility during ● fluoroscopy
- The snare is controllable by advancing and retracting, or rotating, the snare or ● catheter to a position close to the object to be retrieved
- When the snare is appropriately positioned, the snare can be closed onto object by ● advancing a sheath, catheter or tube over the snare
- Ability to torque snare ●
- Ability to manipulate a foreign body ●
- Ability to retrieve snared foreign body into a guide catheter or sheath for removal ● through the vasculature
- Catheter length of subject device within range established by the predicates ●
- Pre-formed snare loop size of subject device within range established by the ● predicates
The following technological differences exist between the subject and the predicate devices:
- . The predicate devices are comprised of individual components (snare, catheter/sheath, snare introducer, torque device) that are assembled into a system by the user at time of use, while the Aveir Retrieval Catheter subject device is comprised of similar components (snare, steerable/deflectable catheter, valve bypass tool (snare introducer), integrated guide catheter) pre-assembled into a single catheter.
- The catheter of the Primary Predicate device (EnSnare) is pre-shaped with an ● angled tip, while the Aveir Retrieval Catheter can be deflected during use per the user's needs.
# VIII. PERFORMANCE DATA
The Aveir™ Retrieval Catheter is substantially equivalent to the predicate devices based on comparisons of the intended use, device functionality, and technological characteristics. The following performance testing was conducted to demonstrate that the device meets its design specifications and is as safe and effective for its intended use.
{7}------------------------------------------------
Image /page/7/Picture/1 description: The image contains the logo for Abbott, a healthcare company. The logo features a stylized, rounded letter 'a' in a bright blue color.

## Animal Testing and Human Factors
Usability validation testing including the Aveir Retrieval Catheter was conducted. The usability acute study was conducted for the intended use workflows where the Aveir Retrieval catheter is utilized along with an Introducer to retrieve an LP via femoral vein. Based on the results of usability validation testing, the Aveir Retrieval Catheter possesses acceptable usability and acceptable residual usability risk based on the observed difficulties and use errors of the participants. All acceptance criteria were met under the conditions of the study. There were no observed use errors that could result in serious patient harm.
In addition, a 182-day Chronic GLP Retrieval Study was performed to demonstrate the safety of retrievability of Aveir Leadless Pacemaker devices at least 182 days post-implant. This GLP study were performed as defined by 21 CFR Part 58 "Good Laboratory Practice for Nonclinical Laboratory Studies" at a USDA registered facility, which is also accredited by AAALAC International.
The ovine subjects were implanted with Aveir Leadless Pacemakers. The subjects had their Aveir Leadless Pacemaker devices successfully retrieved (100% retrieval success rate) using the Aveir Retrieval Catheter by physician operators. All physicians evaluated the safety and performance of the Aveir Retrieval Catheter rated it as good and acceptable or very good and acceptable. Per the board-certified veterinary study pathologist, the gross changes seen at the implant sites in chronically-implanted animal after Leadless Pacemaker retrieval were consistent with atraumatic removal by unscrewing of the device in a counterclockwise manner from the implant site in all animals. All implant sites remained intact following retrieval with an absence of significant trauma and injury to the IVC, right heart, and tricuspid valve apparatus. No retrieval procedure-related or device-related gross changes were seen in draining lymph nodes (pericardial, subaortic, mediastinal, and tracheobronchial).
In summary, these studies demonstrated that the Aveir Retrieval Catheter can safely manipulate and retrieve a foreign object (Aveir LP) from the cardiovascular system.
## Clinical Testing
Clinical evaluation is not required for the Aveir Retrieval Catheter.
{9}------------------------------------------------
Image /page/9/Picture/1 description: The image shows the logo for Abbott. The logo consists of a stylized, rounded letter "a" in blue, positioned above the word "Abbott" in a bold, sans-serif font. The blue color of the "a" and the bold font of the company name give the logo a modern and recognizable appearance.
#### CONCLUSIONS IX.
The resulting evidence obtained from the non-clinical data support the safety of the device and that the Aveir Retrieval Catheter should perform as intended in the specified conditions. The design verification and validation testing demonstrated that the Aveir Retrieval Catheter device performs comparably to the primary predicate device that is currently marketed with the same design features.
Based on the indications for use, technical characteristics, safety, and performance testing, the Aveir Retrieval Catheter is substantially equivalent to the primary predicate EN Snare Endovascular Snare System (K092343), and reference devices Merit ONE Snare System (K122088) and Crux Snare Filter Retrieval Set (K133681). Any differences in the technological characteristics between the devices do not raise any new issues of safety or effectiveness as compared to the predicate device.
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.
