What It Is

The Penumbra System ACE 68 Reperfusion Catheter is a specialized catheter designed for mechanical thrombectomy, a procedure to remove blood clots from the brain's blood vessels in cases of acute ischemic stroke. It works by aspirating the clot through a large-bore catheter, allowing for rapid restoration of blood flow. The device is part of the ADAPT (A Direct Aspiration First Pass Technique) approach, which emphasizes direct aspiration as the first-line treatment.

FDA-Cleared Indications

  • Removal of thrombus from the neurovasculature in patients experiencing acute ischemic stroke.
  • Use in patients who are candidates for mechanical thrombectomy or thrombus removal according to the device labeling and applicable treatment guidelines.

Clinical Applications

  • Endovascular aspiration thrombectomy for acute ischemic stroke caused by an occluding blood clot.
  • Direct aspiration as part of an ADAPT-style approach for eligible cerebral large-vessel occlusions.
  • Clot aspiration through the intracranial arterial circulation under fluoroscopic guidance.
  • Use with compatible aspiration and guide-catheter systems during a hospital-based neurointerventional procedure.

Reported off-label uses

  • Aspiration thrombectomy for selected noncerebral arterial thrombi, such as peripheral arterial occlusion, has been described for this device type but is outside the neurovascular indication and should not be assumed to be FDA-cleared.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

  • The ACE 68 is a large-bore catheter; the operator must confirm compatibility with the access sheath, guide catheter, intermediate catheter, and the patient's vascular anatomy.
  • The catheter is advanced under fluoroscopic guidance, generally through femoral or radial arterial access, and is used with an aspiration source such as a vacuum pump.
  • It is intended for use by clinicians trained in neuroendovascular procedures. Tortuous anatomy, vessel size, vasospasm, dissection, perforation, and bleeding are important procedural considerations.
  • MRI safety depends on the exact device and whether it remains in the patient. A temporary catheter used during a procedure is normally removed before MRI; the manufacturer's current labeling should be checked for any retained component or specific MRI conditions.
  • It is a single-use catheter and is not intended to remain permanently implanted. Contraindications, warnings, and compatibility requirements should be reviewed in the current instructions for use.

Related Literature

The linked study explored the use of the Penumbra ACE and 3MAX reperfusion system in treating patients with symptomatic M2 and M3 occlusions in acute ischemic stroke. The study found that mechanical thrombectomy could be beneficial even in distal vessel occlusions, expanding the potential applications of the device. However, the study's limitations include its initial experience nature and the need for further research to confirm these findings across larger populations.
