Device Story

Variable stiffness, single-lumen catheter; stainless steel braid with PTFE liner; polymer-encapsulated shaft; hydrophilic coating; radiopaque marker band. Used in neurovasculature for aspiration of thrombi in acute ischemic stroke. Operated by physicians in clinical settings (e.g., neuro-interventional suites). Input: manual navigation over guidewire/microcatheter; vacuum pressure from external aspiration pump. Output: mechanical aspiration of thrombus. Benefits: revascularization of occluded intracranial vessels. Connects to aspiration pump via Aspiration Tubing Set; user controls fluid flow via tubing switch.

Clinical Evidence

Bench testing only. Performance testing included static flow rate and aspiration flow rate verification. All samples met established acceptance criteria. No clinical or animal studies were required.

Technological Characteristics

Variable stiffness single-lumen catheter; stainless steel braid; PTFE inner liner; polymer outer jacket; platinum/iridium (90/10) marker band; hydrophilic coating. Dimensions: 125-135 cm length, 0.071 inch ID, 0.081 inch distal OD. Sterilization: Ethylene Oxide. Connectivity: mechanical connection to external aspiration pump.

Indications for Use

Indicated for revascularization in patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (internal carotid, M1/M2 middle cerebral, basilar, vertebral arteries) within 8 hours of symptom onset. Candidates include patients ineligible for or failing IV t-PA therapy.

## Dear Ryan Rivera:

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).

| Device<br>Description | The Cerenovus Large Bore Catheter is a variable stiffness, single lumen catheter<br>designed to be introduced over a steerable guide wire or microcatheter into the neuro<br>vasculature. The catheter shaft is composed of a stainless steel variable pitch braid with<br>a PTFE inner liner to facilitate movement of guide wires and other devices. The<br>exterior of the catheter shaft is covered with polymer materials, which encapsulate the<br>stainless steel braid construction. The catheter has a stiff proximal shaft which<br>transitions into the flexible distal shaft to facilitate the advancement of the catheter in<br>the anatomy. The distal end of the catheter has a radiopaque marker band to facilitate<br>fluoroscopic visualization and has a hydrophilic coating to provide lubricity for<br>navigation of vessels. The proximal end of the catheter has a luer fitting located on the<br>end of the catheter hub which can be used to attach accessories for flushing and<br>aspiration. An ID band is placed at the distal end of the hub over a strain relief. The<br>catheter is packaged with a hemostasis valve with a side port and two peel-away<br>introducers as accessories. The hemostasis valve with side port is used for flushing,<br>insertion of catheters, and connection to an external aspiration system. The peel away<br>introducer sheaths are designed to protect the distal tip of the catheter during insertion<br>into the hemostasis valve.<br>The Cerenovus Large Bore Catheter can be connected to a compatible aspiration pump<br>using the Cerenovus Aspiration Tubing Set. |

| Indications for<br>Use | The Cerenovus Large Bore Catheter, with the Cerenovus Aspiration Tubing Set and a<br>compatible aspiration pump, is indicated for use in the revascularization of patients<br>with acute ischemic stroke secondary to intracranial large vessel occlusive disease<br>(within the internal carotid, middle cerebral - M1 and M2 segments, basilar, and<br>vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for<br>intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are<br>candidates for treatment.<br>The Cerenovus Aspiration Tubing Set is intended to connect the Cerenovus Large Bore<br>Catheter or the CEREGLIDE™ 71 Intermediate Catheter to the canister of a compatible<br>aspiration pump and to allow the user to control the fluid flow. |
