An interventional study of Adaptive Tip Catheter in Ischemic Stroke, sponsored by Neuravi Limited. Recruiting at 13 sites in 4 countries. Open to participants aged 18 Years to 90 Years. Per ClinicalTrials.gov, last updated 2026-11-05.
Sponsored by Neuravi Limited (part of Johnson & Johnson) · Not applicable, Interventional, and Treatment
The purpose of this study is to assess the safety and the effectiveness of the Adaptive Tip Catheter (ATC) used as a first line direct aspiration thrombectomy technique for patients suffering of an acute ischemic stroke.
2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.
This study's planned enrollment of 74 is below the median of 120 across 1,776 interventional studies indexed under Ischemic Stroke.

Exclusion criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

INR, PT and aPTT (clotting tests)
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

The ATC will be used alone (direct aspiration) as the first attempted device/technique for mechanical thrombectomy in the anterior circulation in patients during the first three passes or until final reperfusion, if less than three passes are needed. Patients will be followed over 90 days post procedure.
Procedure: Adaptive Tip Catheter
Patients will undergo mechanical thrombectomy using ATC.
Third Pass Reperfusion Assessed by Independent Imaging Core Lab
Successful achievement of the third pass reperfusion is defined as achieving an Expanded Thrombolysis in Cerebral Infarction (eTICI) score of 2b50 or greater using no more than three passes with the study device in the target vessel, and without any rescue therapy.
Time frame: Intraoperative
First Pass Reperfusion
Successful achievement of the first pass reperfusion is defined as achieving an eTICI score of 2c or greater, as determined by the independent imaging core lab, with one pass of the study device in the target vessel, and without any rescue therapy.
Time frame: Intraoperative
Final Procedural Reperfusion
Successful achievement of the final procedural reperfusion is defined as achieving a final (end of procedure) eTICI score of 2b50 or greater in the target vessel as determined by the independent imaging core lab.
Time frame: Intraoperative
Modified Rankin Scale (mRS) Score of 0-2 at 90 days Post-Procedure
Percentage of patients with mRS score of 0-2 at 90 days or no change from baseline if pre-ictal mRS greater than (\>) 2 will be reported.
Time frame: At 90 days post-procedure
Vessel Damage
Number of patients with perforation or dissection in the blood vessel known to be related to or possibly related to the study device will be reported.
Time frame: At 90 days post-procedure
All-Cause Mortality
All mortality regardless of causes at 90 days post-procedure will be reported.
Time frame: At 90 days post-procedure
Symptomatic Intracranial Hemorrhage (sICH) at 24 hours
sICH is defined as a new intracranial hemorrhage as detected by brain imaging, measured 24 hours after intervention associated with any of the following: greater than or equal to (\>=) 4 points total National Institutes of Health Stroke Scale (NIHSS) at the time of diagnosis compared to immediately before worsening; \>= 2 point in one NIHSS category; leading to intubation/hemicraniectomy/external ventricular drain (EVD) placement or other major medical/surgical intervention or absence of alternative explanation for deterioration.
Time frame: At 24 hours after intervention

Started Feb 2026 (actual). Primary completion is estimated for Apr 2027, 14 months after the start.
Of 81 industry-sponsored interventional studies with no phase under Ischemic Stroke, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 46. This study's planned 14 months is below that.
Counting every sponsor, half of 653 studies reached it within 27 months; a quarter within 14 and three quarters within 48.
