About this study
The purpose of this registry is to assess clinical outcomes, and different factors that may affect these clinical outcomes such as systems of care, associated with the use of Covidien market-released neurothrombectomy devices intended to restore blood flow in patients experiencing acute ischemic stroke due to large intracranial vessel occlusion.
Read the detailed description
This is a prospective, multi-center, non-randomized, observational registry of acute ischemic stroke patients that have or will undergo treatment with the use of a Covidien market-released neurothrombectomy device (as the initial device used to remove the thrombus) within 8 hours of stroke symptom onset, at the discretion of the investigator and independent of participation in this registry. This registry may enroll up to 1000 patients.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Medtronic NV market-released device | Patients experiencing an acute ischemic stroke due to a large vessel occlusion treated with a Medtronic Neurovascular market-released neurothrombectomy device. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Assessed for Revascularization With mTICI Grades 2b-3
Assess revascularization using modified Thrombolysis in Cerebral Infarction (mTICI) score at the end of the procedure. This scale determines the response of therapy for ischemic stroke based on angiographic appearances of the treated occluded vessel and the distal branches.
Classification:
grade 0: no perfusion grade 1: antegrade reperfusion past the initial occlusion, but limited distal branch filling with little or slow distal reperfusion grade 2a: antegrade reperfusion of less than half of the occluded target artery previously ischemic territory grade 2b: antegrade reperfusion of more than half of the previously occluded target artery ischemic territory grade 3: complete antegrade reperfusion of the previously occluded target artery ischemic territory, with absence of visualized occlusion in all distal branches (higher values represent better outcomes)
Measured: Day 0-At the completion of the thrombectomy procedure
Secondary outcomes (1)
Incidence of Neurological Events of Interest
Evaluate events causing neurological deterioration (defined as ≥ 4 worsening points from baseline on the NIHSS scale)
Measured: up to 90 days post index procedure

Questions about this trial
What is this clinical trial studying?
An observational study of Ischemic Stroke, run by Medtronic Neurovascular Clinical Affairs at 55 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 55 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 7 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Assessed for Revascularization With mTICI Grades 2b-3 (time frame: Day 0-At the completion of the thrombectomy procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02239640, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jun 2019.
