Intended Use

The CerusEndo Microcatheter (027) is intended to deliver therapeutic devices within the neurovasculature.

Device Story

The CerusEndo Microcatheter (027) is a percutaneous, neurovascular catheter designed to deliver therapeutic devices (e.g., occlusion coils) to discrete locations within the neurovasculature. The device features a polymer tapered shaft, stainless steel reinforcement, a Teflon-lined inner lumen, and a hydrophilic coating. The distal segment is flexible for navigation through tortuous anatomy, and the distal tip is steam-shapeable by the physician at the point of use. The device is operated by a physician in hospital interventional neuroradiology suites; it is advanced over a guidewire through a guide catheter. The device is supplied sterile for single use. By providing a trackable, shapeable conduit, the catheter facilitates the precise placement of therapeutic implants, potentially improving clinical outcomes in neurovascular interventions.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including tensile strength, shaft flexibility, shape retention, kink resistance, static burst pressure, simulated use, particulate assessment, coating durability, and torque testing. Biocompatibility was confirmed per ISO 10993-1, including cytotoxicity, hemocompatibility (hemolysis, complement activation), and canine carotid thrombogenicity studies.

Technological Characteristics

Percutaneous catheter; 150/160 cm lengths; 0.027 in ID. Materials: Pebax outer/inner layers, stainless steel braid/coil, PTFE liner, platinum/iridium marker, nylon hub. Features: hydrophilic coating, steam-shapeable distal tip. Sterilization: Ethylene oxide. Biocompatibility: ISO 10993-1 compliant. Connectivity: None (manual).

Indications for Use

Indicated for patients undergoing vascular procedures requiring delivery of therapeutic devices within the neurovasculature.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

Dear Lori Adels:

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.

## VIII. CONCLUSION

After a comparison of the subject CerusEndo Microcatheter (027) intended use, technological characteristics, and expected performance to the legally marketed predicate, the Headway 27 Microcatheter (K142449), Cerus Endovascular concludes that the CerusEndo Microcatheter (027) is substantially equivalent to the legally marketed predicate device. The differences between the subject device and the predicate do not raise different questions of safety and effectiveness.
