- Adult, Older adult
Who may be able to join

Who cannot join
- Severe comorbidity and/or shortened life expectancy that will likely prevent improvement or follow up or that will render the procedure unlikely to benefit the patient.

- Severe sustained hypertension (systolic pressure >185 mm Hg or diastolic pressure >110 mm Hg). Note: If blood pressure can be successfully reduced and maintained at an acceptable level by administering the medication recommended by the ESO (European Stroke Organisation) in its guidelines (also IV infusion of antihypertensives), the subject may be included.
- Known or suspected cerebral vasculitis.
- Known renal insufficiency with creatinine ≥3 mg/dl or Glomerular Filtration Rate (GFR) <30 mL/min.
- Current participation in an interventional drug or device study that may confound the results of this study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Thromboaspiration catheterDevice
Patients to undergo thromboaspiration with iNstroke 5F
| Study group | Role | What they receive |
|---|---|---|
| Thromboaspiration using iNstroke 5F aspiration catheter | Other | No comparator will be used as this is a traditional feasibility clinical investigation. The objective is to capture preliminary clinical performance, effectiveness and safety information to adequately plan an appropriate pivotal clinical investigation. Receives: Device: Thromboaspiration catheter |
What is being measured
The primary outcome is the main question the study is designed to answer.
Recanalization Rate
Recanalization rate with mTICI ≥2b in ≤3 revascularization passes using iNstroke Thrombus Extraction Aspiration Device aspiration catheter alone, or in conjunction with Stent Retriever
Measured: Intra-procedure

Questions about this trial
What is this clinical trial studying?
A study testing Thromboaspiration catheter in people with Acute Ischemic Stroke, run by iVascular S.L.U. at 7 sites in 2 countries.
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 8 inclusion and 15 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: opening soon, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in Spain, France. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recanalization Rate (time frame: Intra-procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 5 Nov 2026.
