Intended Use

Raptor Aspiration Catheter: The Raptor Aspiration Catheter with a compatible aspiration pump and Balt Aspiration Tubing Set is indicated 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. Balt Aspiration Tubing Set: The Balt Aspiration Tubing Set is intended to connect the Raptor Aspiration Catheter to the canister of a compatible aspiration pump and to allow the user to control the fluid flow.

Device Story

Raptor Aspiration Catheter is a single-lumen, variable stiffness composite catheter used for thrombus removal from neurovasculature. Device inputs include vacuum pressure from a compatible aspiration pump, delivered via the Balt Aspiration Tubing Set. The catheter features a distal markerband, hydrophilic coating, and luer fitting for navigation and fluid infusion. Used in clinical settings by physicians, the device is navigated to the occlusion site; aspiration is applied to remove thrombus. Output is the physical removal of the clot, facilitating revascularization. Benefits include restoration of blood flow in acute ischemic stroke patients. The tubing set allows user control of fluid flow and vacuum connection to the pump canister.

Clinical Evidence

No clinical data. Substantial equivalence is based on non-clinical bench testing, including dimensional verification, tensile strength, kink resistance, leakage, burst pressure, torque strength, particulate matter, radiopacity, and clot retrieval in clinically relevant anatomical models.

Technological Characteristics

Single-lumen composite catheter; variable stiffness; hydrophilic coating. Materials: medical-grade plastics and metals. Dimensions: 0.038"-0.054" ID; 0.051"-0.074" OD. Sterilization: Ethylene Oxide (EO) to SAL 10^-6. Standards: ISO 10555-1 (mechanical), ISO 10993-1 (biocompatibility), ISO 80369-7 (hub), ASTM F1980 (aging).

Indications for Use

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

Dear Catherine Chiou:

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.

A determination of substantial equivalence is based upon successful completion of non-clinical bench testing.

## Performance Data – Clinical:

A determination of substantial equivalence is based upon successful completion of non-clinical bench testing.

## Conclusion:

Based on the same intended use, similar technological characteristics, and the results of the non-clinical testing, the Raptor Aspiration Catheter and Balt Aspiration Tubing Set is found to be substantially equivalent to the predicate device. The differences in technological characteristics do not raise new questions of safety and effectiveness. Testing was conducted to demonstrate that the subject device meets the specifications and performs as intended.
