Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Successful Revascularization

    Successful revascularization was defined as achieving a final modified thrombolysis in cerebral infarction (mTICI) score of 2b or greater in target vessel. Revascularization was measured by an independent adjudicating imaging core laboratory and were reported using expanded treatment in cerebral infarction (eTICI) scale. eTICI was a 7-point grading system for determining response of thrombolytic therapy for ischemic stroke: 0=No reperfusion; 0 percent(%) filling of downstream territory; 1=Thrombus reduction without any reperfusion of distal arteries; 2a=Reperfusion in less than half (1-49%) of the territory; 2b=2b50 (reperfusion in \[50-66%\] of downstream territory) and 2b67 (reperfusion in (67-89%) of downstream territory); 2c=Reperfusion in \[90-99%\] of downstream territory; 3=Complete and 100% reperfusion where higher score indicated more successful revascularization.

Interventions

The EMBOVAC Aspiration catheter is used to treat acute ischemic stroke. The catheter can be used to facilitate introduction of diagnostic or therapeutic agents and is also intended for use in removal/aspiration of emboli and thrombi from selected blood vessels in the neuro vasculature.

Sampling MethodNon-Probability Sample
Study Population

Acute Ischemic Stroke patients with confirmed intracranial large vessel occlusion.

You may qualify if:

  • Subject ≥ 18 years old.
  • Subject experiencing acute ischemic stroke with angiographic confirmation of Large Vessel Occlusion of the distal intracranial internal carotid artery, middle cerebral artery or anterior cerebral artery
  • A clinical decision has been made to use the EMBOVAC™ aspiration catheter prior to enrollment in the research
  • EMBOVAC™ Aspiration Catheter is attempted to be used for the first 3 clot removal passes for the target intracranial occlusion
  • Pre-stroke mRS ≤ 1
  • NIHSS ≤ 30
  • Informed Consent has been provided by the subject or the subject's legally authorized representative.

You may not qualify if:

  • Potential study candidate has already undergone standard of care assessments or treatment that deviate from the clinical research protocol requirements
  • All patients with severe hypertension on presentation. All patients, in whom intravenous therapy with blood pressure medications is indicated, with hypertension that remains severe and sustained despite intravenous antihypertensive therapy
  • Known cerebral vasculitis.
  • Known cancer with life expectancy less than 12 months.
  • Stenosis, or any occlusion, in a vessel proximal to the target occlusion that requires treatment or prevents access to the site of occlusion.
  • Computed tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage on presentation.
  • Baseline computed tomography (CT) or MRI showing mass effect or intracranial tumor (except small meningioma).
  • Evidence of dissection in the extra or intracranial cerebral arteries.
  • Occlusions in multiple vessels.
  • Confirmation of positive pregnancy test according to site specific standard of care (e.g. test, verbal communication).
  • Currently participating in an investigational clinical trial that may confound study endpoints.
