Cangqian Sub-District, Yuhang District Hangzhou, Zhejiang 311121 China Re: K260416 Trade/Device Name: ZYLOX Hippo PTA Balloon Dilatation Catheter Regulation Number: 21 CFR 870.1250 Regulation Name: Percutaneous Catheter Regulatory Class: Class II Product Code: LIT Dated: August 17, 2026 Received: August 18, 2026 Dear Siran Wu: 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. U.S. Food & Drug Administration 10903 New Hampshire Avenue Silver Spring, MD 20993 www.fda.gov {1} K260416 - Siran Wu Page 2 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 Management System Regulation (QMSR) (21 CFR Part 820), which includes, but is not limited to, ISO 13485 clause 7.3 (Design controls), ISO 13485 clause 8.3 (Nonconforming product), ISO 13485 clause 8.5.2 (Corrective action), and ISO 13485 clause 8.5.3 (Preventative action). Please note that regardless of whether a change requires premarket review, the QMSR requires device manufacturers to review and approve changes to device design and production (ISO 13485 clause 7.3 and ISO 13485 clause 7.5) and document changes and approvals in the Medical Device File (ISO 13485 clause 4.2.3). 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 Management System Regulation (QMSR) (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.

Predicate Device Information | Identification | Manufacturer | Device Name | 510(K) Number | | --- | --- | --- | --- | 1 / 4 {5} K260416 | Predicate Device | Boston Scientific Corporation | Athletis™ PTA Balloon Dilatation Catheter | K201170 | | --- | --- | --- | --- | | Reference Device | C.R. Bard, Inc. | Conquest™ 40 PTA Dilatation Catheter | K212588 | ## 6. Device Description The ZYLOX Hippo PTA Balloon Dilatation Catheter is a high performance over-the-wire (OTW) balloon catheter consisting of distal tip, radiopaque markers, balloon, catheter, catheter hub and catheter hub strain reinforcement. The proprietary non-compliant, low profile balloon is designed to provide consistent balloon diameters and lengths even at high pressures. The catheter features a dual-lumen shaft ending in a Y-connector catheter hub with luer lock fittings. One of the port connects to a balloon inflation device for balloon inflation and deflation, while the other port is used to deliver the catheter over a 0.035 inch (0.89 mm) guidewire. Two radiopaque marker bands, in conjunction with fluoroscopy, aid in the visualization of the balloon. The catheter includes a soft and tapered distal tip to facilitate advancement of the catheter to and through the treatment site. The balloon catheter is available in working lengths of 50 cm, 75 cm, and 135 cm to accommodate various anatomical requirements. ## 7. Indications for Use The ZYLOX Hippo PTA Balloon Dilatation Catheter is indicated for Percutaneous Transluminal Angioplasty in the peripheral vasculature including upper extremity, renal, iliac, and infra-inguinal vessels and the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.
