Intended Use

The Micro Catheter and Guidewire System is intended for the infusion of contrast media into the peripheral vessels. The Micro Catheter and Guidewire system is also infusion in intra-arterial therapy and the infusion of embolic materials for hemostasis. The system should not be used in cerebral vessels.

Device Story

System comprises catheter, guidewire, and accessories (flushing device, shaping mandrel, insertion tool, torque device, peel-able tube). Used by clinicians in peripheral vascular procedures. Catheter features PTFE inner layer, stainless steel wire reinforcement, platinum-iridium radiopaque marker, polyamide outer layer, and hydrophilic coating. Guidewire features nitinol core, polymer jacket with PVP hydrophilic coating, and distal spring coil. Device facilitates targeted delivery of contrast, therapeutic drugs, or embolic agents to peripheral vasculature. Clinician navigates system to target site; output is delivery of therapeutic/diagnostic agents. Benefits include precise vessel access and agent delivery.

Clinical Evidence

Bench testing only. No clinical data provided. Performance verified via biocompatibility testing (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemolysis, PTT, complement activation, thrombogenicity) and mechanical bench testing (tensile force, leakage, torque, kink resistance, radiopacity, burst pressure, simulated use, tip flexibility).

Technological Characteristics

Catheter: PTFE inner, stainless steel wire reinforcement, platinum-iridium radiopaque marker, polyamide outer layer, hydrophilic coating. Guidewire: Nitinol core, polymer jacket, PVP hydrophilic coating, distal spring coil. Sterile, single-use. Mechanical sensing/delivery principle.

Indications for Use

Indicated for infusion of contrast media, drugs for intra-arterial therapy, and embolic materials for hemostasis in peripheral vessels. Contraindicated for use in cerebral vessels.

Regulatory Classification

Identification

A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping.

Dear Wang Peipei:

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

{1}------------------------------------------------

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 https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) 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.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
