Intended Use

The Riptide™ Aspiration System is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for thrombolytic drug therapy or who failed thrombolytic drug therapy are candidates for treatment.

Device Story

Riptide Aspiration System restores blood flow in acute ischemic stroke patients. System components: React 68/71 catheters, large bore aspiration tubing, aspiration pump, and collection canister. Physician inserts catheter into intracranial vasculature; pump provides continuous aspiration to remove thrombus. Output is collected in canister. Used in clinical settings (e.g., neurointerventional suites). Device aids in revascularization, potentially improving patient outcomes by restoring cerebral perfusion.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

System includes aspiration catheters (hydrophilic coated medical grade plastics/metals), aspiration pump (0-29 inHg vacuum), tubing, and collection canister. Pump is Type CF applied part. Complies with IEC 60601-1 (Ed 3.2), IEC 60601-1-2 (Ed 4.1), ISO 10079-1, and ISO 10079-4. Sterilization via ethylene oxide (SAL 10-6) for catheters.

Indications for Use

Indicated for patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (internal carotid, middle cerebral M1/M2, basilar, vertebral arteries) within 8 hours of symptom onset. Candidates include those ineligible for or who failed thrombolytic drug therapy.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

Dear Tony Rizzardi:

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.

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

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 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-reportingcombination-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-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

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

## Performance Data – Animal

The determination of substantial equivalence is based upon non-clinical bench testing as there is no change to the intended use, fundamental scientific technology, or materials of construction.

# Performance Data - Clinical

The determination of substantial equivalence is based upon non-clinical bench testing as there is no change to the intended use, fundamental scientific technology, or materials of construction.

# Conclusion

There is no change to the intended use, fundamental scientific technology, principle of operation, and materials of construction of the subject Riptide™ Aspiration System in comparison to the legally marketed predicate Riptide™ Aspiration System (K201689). The design and labeling changes for Type CF applied part classification, meeting latest electrical safety and medical suction equipment standards (including IEC 60601-1, IEC 60601-1-2, ISO 10079-1, and ISO 10079-4), and addition of shorter length sizes of the React™ 71 Catheter (REACT-71-115 & REACT-71-125) to the system do not raise new questions of safety and effectiveness and have been tested through non-clinical bench testing using established scientific methods. The information provided in this submission supports a determination of substantial equivalence for the subject Riptide™ Aspiration System.
