• Intracranial hemorrhage confirmed by imaging
• Any other condition that precludes the performing of mechanical thrombectomy procedure
• Subjects who are allergy to the contrast agent
• Any other condition that, according to the investigator's judgement, not suitable for using of balloon guide catheter
• Known or suspected pre-existing (chronic) large vessel occlusion in the symptomatic territory
• Excessive vascular access tortuosity disables the use of balloon guide catheter
• Intracranial stent implanted in the same vascular territory that precludes the safe deployment/removal of the neuro-thrombectomy device
• Occlusions in multiple vascular territories confirmed by Computed Tomography Angiography(CTA) or Magnetic Resonance Angiography(MRA)
• Subjects who are pregnant
• Subjects who refuse to cooperate or unable to tolerate interventional operation
• Subjects whose expected lifetime are less than 90 days
• Subjects who are unlikely to participate in follow-up assessments according to the investigator's judgement
