Dear Kimberly Jacob-Paredes:

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.

# NON-CLINICAL TESTS

## Performance

Performance testing was conducted to verify the safety and effectiveness of the Midline Catheter. This device is intended for short-term use (less than 30 days) for blood sampling or intravenous fluid administration. It is suitable for all patient populations, with consideration given to the adequacy of vascular anatomy and appropriateness of the procedure. The Midline catheter is compatible with power injectors throughout its shelf life. Testing was performed to confirm compliance with relevant internal and external standards, demonstrate MR Conditional status, and establish substantial equivalence to the predicate device. Performance tests were carried out on both non-aged and accelerated-aged samples. Table 4 below outlines the specific performance tests conducted on the Midline Catheter.

# MRI Compatibility Testing

MRI compatibility testing was conducted on the finished Midline Catheter, excluding the needle component. To remove the needle, the device's safety mechanism must be activated; therefore, only the catheter and catheter hub were included in the evaluation. Testing was performed in accordance with the recommendations outlined in the FDA Guidance Document for Industry and FDA Staff, "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment." The objective was to determine MR Conditional safety information for the device. Table 5 below summarizes the MRI tests performed on the Midline Catheter.

Table 5: Summary of MRI Tests Performed

| Test Items | Applicable Standards |
| --- | --- |
| Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the Magnetic Resonance Environment | ASTM F2052-21 |
| Standard Test Method for Measurement of Magnetically Induced Torque on Medical Devices in the Magnetic Resonance Environment | ASTM F 2213-2017 |
| Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants | ASTM F2119-07(2013) |

Performance testing for $t = 0$ and $t = 36AA$ (3-year accelerated age) and the MRI Compatibility testing confirmed that all predetermined acceptance criteria were met. The results support that the Midline Catheter is suitable for clinical use throughout its labeled shelf life and meets the criteria for MR Conditional.
