Inclusion criteria

  1. The consent process has been completed with the subject, Legally Authorized Representative, or two physician best interest and consent is documented
  2. Age >18 years
  3. Clinical signs consistent with an acute ischemic stroke
  4. Baseline National Institutes of Health Stroke Scale (NIHSS) score >= 6
  5. Pre-stroke modified Rankin Score (mRS) \<= 2
  6. Acute occlusion of the M1 segment of the middle cerebral artery (MCA), internal carotid artery (ICA), vertebral or basilar arteries confirmed via computed tomography angiography (CTA) and/or magnetic resonance angiography (MRA)
  7. The Investigator estimates that at least one delivery of the Route 92 Medical Reperfusion System can be completed within 24 hours of time last known well
  8. In the opinion of the Investigator, reperfusion of the ischemic territory will result in clinical benefit
  9. Angiographic confirmation of an occlusion of the M1 segment* of the middle cerebral artery, internal carotid artery, vertebral or basilar arteries with a modified Thrombolysis In Cerebral Infarction (mTICI) scale score of 0-1

Exclusion criteria

Exclusion Criteria:

  1. Known pregnancy or breast feeding
  2. Known comorbidity that may complicate treatment or prevent improvement or follow-up
  3. Known life expectancy \< 12 months
  4. Known history of severe allergy to contrast medium
  5. Subject known to have suffered a stroke in the past 90 days
  6. Subject participating in another study involving an investigational device or drug.
  7. Known connective tissue disorder affecting the arteries (e.g. Marfan syndrome, fibromuscular dysplasia, Ehlers-Danlos syndrome)
  8. Any known pre-existing hemorrhagic or coagulation deficiency
  9. Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage
  10. Baseline CT or MRI showing intracranial tumor (except small meningioma)
  11. Angiographic evidence of dissection in the extracranial or intracranial arteries
  12. Angiographic evidence of carotid dissection
  13. Angiographic evidence of multiple vascular occlusions (e.g., bilateral anterior circulation, anterior/posterior circulation). Note: tandem occlusions may be included at the discretion of the operating physician.

Study arms

  • Experimental
    Thrombectomy

    Aspiration of clot with large bore catheter in acute ischemic stroke patients

    Device: Thrombectomy

Interventions

  • DeviceThrombectomy

    The Route 92 Medical Reperfusion System 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, basilar and vertebral arteries.

What researchers measure

Primary outcomes

  1. Effectiveness

    The primary effectiveness endpoint is arterial revascularization as measured by a modified Thrombolysis in Cerebrovascular Infarction (mTICI) score of 2b or greater at the end of angiography after all endovascular treatments.

    Time frame: Procedure

  2. Device-related peri-procedural complications

    dissection or perforation

    Time frame: Procedure

  3. Symptomatic Intracranial Cerebral Hemorrhage (SICH)

    defined as type 2 parenchymal hemorrhage with a deterioration in National Institutes of Health Stroke Scale \[NIHSS\] score of \>=4 points

    Time frame: 24 hour

  4. Embolization to a previously uninvolved territory

    Embolization to a previously uninvolved territory

    Time frame: Procedure

Secondary outcomes

  1. NIHSS score

    The National Institutes of Health Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke

    Time frame: 24 hours after treatment

  2. Modified Rankin Score

    The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or who have other causes of neurological disability

    Time frame: 90 days after treatment

  3. Procedure Time

    Total procedure time from insertion of Route 92 Reperfusion System to final angiogram

    Time frame: Procedure

  4. Procedure-Related SAEs

    Serious Adverse Events related to the interventional procedure

    Time frame: Procedure
