The goal of this pilot study is to evaluate the safety and efficacy of the Toro 88 Super Bore Aspiration Catheter in acute ischemic stroke patients.

This is a prospective, open-label, single-arm, single-center clinical investigation evaluating the safety and efficacy of the Toro 88 Super Bore Aspiration Catheter in mechanical thrombectomy for acute ischemic stroke. The study is being conducted at the Hôpital Fondation Adolphe de Rothschild in France.

Inclusion Criteria:

• Patients aged ≥ 18 and ≤ 90 years at the time of consent

• Presenting with an acute ischaemic stroke for which symptoms (or last time seen as normal) are < 24h

• With occlusion of the ICA / the M1 segment of the MCA / a vertebral artery diameter ≥3.5mm / the basilar artery, defined by eTICI≤1

• Requiring endovascular treatment (mechanical thrombectomy) with or without intravenous thrombolysis

• For whom the experimental device is the first-line treatment

• Without pre-existing disability (mRS ≤3 and 6≤ NIHSS ≤30 before stroke)

• Informed consent signed :

  • By the patient
  • Or consent by a family member/trusted support person if the patient's condition does not allow them to express their consent in writing (L1111-6)

Exclusion Criteria:

• Arterial dissection
