The device description and performance testing sections focus on the physical characteristics and mechanical performance of a catheter, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The "Mentions AI, DNN, or ML" and "Description of the training set, sample size, data source, and annotation protocol" sections are explicitly marked as "Not Found".
No.
This device is an intermediate catheter used to facilitate the insertion and guidance of other interventional devices, or for retrieving devices, not to directly treat a medical condition.
No
Explanation: The device is a catheter designed to facilitate the insertion and guidance of interventional devices and for use as a conduit for retrieval devices. Its described functions are all related to delivery or retrieval of other instruments within the neurovascular system, not to diagnosing conditions.
No
The device description clearly details a physical catheter with various material components, a lumen, a radiopaque marker band, and accessories like a Tuohy Borst valve and slit introducers. This is a hardware medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used to facilitate the insertion and guidance of interventional devices into blood vessels and as a conduit for retrieval devices. This is a therapeutic or interventional use, not a diagnostic one.
- Device Description: The description details a catheter designed for physical manipulation within the neurovascular system. This aligns with an interventional device, not a device used to examine specimens from the body.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, tissue, etc.) to provide diagnostic information. IVDs are typically used in laboratories or point-of-care settings to detect or measure substances in these samples.
The device is a medical device used for interventional procedures within the neurovascular system.

QJP
Device Description
The CEREGLIDE™ 71 Intermediate Catheter is a variable stiffness, single lumen catheter designed to be introduced over a steerable guide wire or microcatheter into the neuro vasculature. The catheter shaft is composed of a stainless steel variable pitch braid with a PTFE inner liner to facilitate movement of guide wires and other devices. The exterior of the catheter shaft is covered with polymer materials, which encapsulate the stainless steel braid construction. The catheter has a stiff proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. The distal end of the catheter has a radiopaque marker band to facilitate fluoroscopic visualization and has a hydrophilic coating to provide lubricity to reduce friction during navigation in the vasculature. The proximal end of the catheter has a luer fitting located on the end of the catheter hub. An ID band is placed at the distal end of the hub over a strain relief.
The catheter is packaged with a Tuohy Borst rotating hemostasis valve (RHV) with a side port and two slit introducers as accessories. The RHV with side port is used for flushing and insertion of catheters. The slit introducers are designed to introduce the catheter into the base catheter and protect the distal tip of the catheter during insertion into the RHV of the base catheter.

Dear Ariell Joiner:
We have reviewed your 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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
1
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

activation fragment, SC5b-9, which in turn contributes to the
inflammatory immune response in humans. | PASS |
| ASTM Heparinized
Platelet and
Leukocyte Count | Determination if medical materials exposed to human whole
blood would adversely affect the platelet and leukocyte ratios in
whole blood. | PASS |
| ASTM Partial
Thromboplastin
Time (PTT) | Screening for detection of coagulation abnormalities in the
intrinsic coagulation pathway. The PTT indirectly measures the
formation of thrombin by its action on fibrinogen, forming the
fibrin clot through a method compliant with ISO 10993-4. | PASS |
| In Vivo
Thromboresistance | Evaluate the thrombogenic potential of a blood contacting
medical device in comparison to a predicate device. | PASS |

IX. Conclusion
Based upon the intended use, design, materials, function, and side-by-side in-vitro and in-vivo testing, it is concluded that the subject device, CEREGLIDE™ 71 Intermediate Catheter is substantially equivalent to the predicate device, CERENOVUS Large Bore Catheter (K191237). The differences in materials and design do not raise new questions regarding the safety and effectiveness of the device. The device, as designed, manufactured, packaged and sterilized, is substantially equivalent to the primary predicate and reference devices currently marketed under the Federal Food, Drug and Cosmetic Act.
