Intended Use

The CenterFlow Molding Balloon Catheter is intended to assist in the dilatation of self-expanding endoprostheses in large-diameter vessels.

Device Story

The CenterFlow Molding Balloon Catheter is a single-use, over-the-wire device designed to assist in the dilatation of self-expanding endoprostheses within large-diameter vessels. It features two elongated, non-compliant nylon balloons constrained in a zig-zag arrangement within a nitinol support frame. Upon inflation, the balloons straighten, expanding the device head while creating a central orifice that maintains hemodynamic flow during the molding procedure. The device is inserted over a 0.035" guidewire through a transfemoral introducer sheath. Platinum-iridium markers allow for angiographic visualization for precise placement. The catheter connects to a Y-connector for inflation/deflation and guidewire access. It is intended for use by clinicians in a procedural setting to facilitate endoprosthesis expansion without completely obstructing blood flow, potentially reducing hemodynamic instability during the procedure.

Clinical Evidence

No clinical data provided. Evidence consists of benchtop performance testing, biological safety evaluation, biocompatibility testing, in vivo safety evaluation, packaging validation, and shelf-life validation.

Technological Characteristics

Dear Robert Packard:

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 (the 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 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.

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).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

3. Device Description Summary

The CenterFlow Molding Balloon Catheter is intended to assist in the dilatation of self-expanding endoprostheses in large diameter vessels. When used in its indications for use, it is a low-permissive, over-the-wire, single-use device comprised of two elongated non-compliant nylon balloons that are attached to and within a nitinol support frame. The two elongated balloons are constrained in a zig-zag arrangement by the nitinol support frame. Upon inflation, this configuration enables expansion of the device head through balloon straightening, to assist the dilatation of self-expanding endoprostheses in large diameter vessels. Expansion of the zig-zag balloon configuration creates a central orifice permitting maintained hemodynamic flow during the molding procedure.

The inflation lumen is 9 Fr and is made of PEBAX 72D. A co-axial PEBAX 72D guidewire lumen runs through the inflation lumen and device head and terminates into a distal polycarbonate tip. Two platinum-iridium markers provide angiographic visualization of the distal and proximal balloon edges to facilitate intravascular balloon placement prior to inflation. The catheter has a working length of 110 cm and it connects proximally to a standard Y-connector at the proximal end. The Y-connector allows for separation of two lumens - an angled luer-lock hub to inflate and deflate the balloon and a straight luer-lock hub which accepts a 0.035" guidewire. The device is deflated and inserted over the guidewire through the hemostasis valve of a transfemoral introducer sheath.
