Outcome Measures

Primary Outcomes (1)

  • technical success rate of ewata

    When the balloon guiding catheter arrives at the desired location, the thrombectomy instrument can enter the balloon guiding catheter smoothly, which can be opened successfully when needed to form a local blockage of blood flow. After the thrombectomy, the thrombectomy instrument can be withdrawn back into the guide catheter, which is considered as a success.Ewata balloon guide catheter should be used at least once during thrombectomy

    intraoperative

Secondary Outcomes (9)

  • Rate of Vascular recanalization

    postoperative

  • Rate of intraoperative adverse events

    intraoperative

  • The time from the successful puncture to the expected location of ewata

    intraoperative

  • The time from successful puncture to recanalization

    intraoperative

  • Rate of symptomatic intracranial hemorrhage within 24 hours

    24 hours

  • +4 more secondary outcomes

EXPERIMENTAL

To evaluate the efficacy and security of Ewata combined with a stent device in the treatment of acute ischemic stroke within 8 hours To prove whether the clinical efficacy and safety of Ewata r is not inferior to other guidings.

Device: Ewata balloon guiding

Interventions

The balloon guide catheter is coaxial cavity and reinforced braided catheter with varying stiffness echelon.The distal end is marked by an impermeable ray, the proximal end has a bifurcated ruhr interface, and the end is embedded with a compliance balloon.The product label indicates the size of the balloon guide catheter and the maximum volume of the balloon.
