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 available 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. {1}------------------------------------------------ Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Device Description Both the CEREGLIDE™ 42 Intermediate Catheter and CEREGLIDE™ 57 Intermediate Catheter (hereafter referred to as the CEREGLIDE™ 42 and CEREGLIDE™ 57 Intermediate Catheters) are variable stiffness, single lumen catheters designed to be introduced over a steerable guide wire or microcatheter into the neuro vasculature. The catheter shaft is composed of a stainlesssteel 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 catheter hub which can be used to attach accessories for flushing. 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.

Prior to aging, all samples were exposed to standard transportation conditioning. Results of shelf-life performance testing all met established acceptance criteria. ### Biocompatibility Testing A biological safety evaluation was conducted for the CEREGLIDE™ 42 and CEREGLIDE™ 57 Intermediate Catheters in accordance with the FDA biocompatibility guidance, "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process"" (issued September 2023). Additionally, biocompatibility testing conducted on the CEREGLIDE™ 71 Intermediate Catheter (K221930), per ISO 10993-1 and applicable regulatory requirements, adequately evaluates the biocompatibility profile of the CEREGLIDE™ 42 and CEREGLIDE™ 57 Intermediate Catheters for endpoints recommended by the FDA biocompatibility guidance for an externally communicating device with limited (≤24 hours) duration of contact with circulating blood. The CEREGLIDE™ 42 and CEREGLIDE™ 57 Intermediate Catheters have met the requirements of biocompatibility assessments, for their intended use. Continued on the next page {8}------------------------------------------------ IX. Conclusion Based upon the intended use, design, materials, function, and side-by-side in-vitro testing, it is concluded that the subject devices, the CEREGLIDE™ 42 and CEREGLIDE™ 57 Intermediate Catheters, are substantially equivalent to the predicate device, AXS Vecta 46 Intermediate Catheter (K202752). The differences in materials and design do not raise new questions regarding the safety and effectiveness of the devices. The subject devices, as designed, manufactured, packaged, and sterilized, are substantially equivalent to the primary predicate device currently marketed under the Federal Food, Drug and Cosmetic Act.
