• Attributes: Therapeutic

Intended Use

The product (FineCross M3) is intended to be percutaneously introduced into blood vessels and support a guide wire while performing PCI (percutaneous coronary intervention). The product is also intended for injection of radiopaque contrast media for angiography. The product should not be used in cerebral and peripheral vessels.

Device Story

FineCross M3 is a single-use microcatheter used during percutaneous coronary intervention (PCI). It features a three-layer construction: stainless steel mesh braid between polyester elastomer and polytetrafluoroethylene layers, with a hydrophilic coating. Operated manually by a physician in a clinical setting, the device is introduced percutaneously into coronary blood vessels to support a guidewire (up to 0.014") and facilitate the injection of radiopaque contrast media for angiography. The device assists the physician in navigating coronary vasculature, improving guidewire placement and procedural visualization. It is sterilized via ethylene oxide.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing, including radio-detectability, tensile force, leakage, flow rate, torque strength, kink resistance, coating integrity, and simulated use usability testing. Biocompatibility was verified per ISO 10993-1.

Technological Characteristics

Three-layer catheter shaft: stainless steel mesh braid, polyester elastomer, and polytetrafluoroethylene. Hydrophilic polymer coating. Distal 1.8 Fr / Proximal 2.5 Fr. Max guidewire 0.014". Sterilized via ethylene oxide (ISO 11135:2018).

Indications for Use

Indicated for patients undergoing percutaneous coronary intervention (PCI) requiring guide wire support and radiopaque contrast media injection. Contraindicated for use in cerebral and peripheral vessels.

Regulatory Classification

Identification

Dear Vaibhav Sivaramakrishan:

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/cfpmp/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 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
