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 After the thrombectomy, the thrombectomy instrument can be withdrawn back into the guide catheter, which is considered as a success.Ewata balloon guide catheter should be used at least once during thrombectomy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
Study Arms (1)
balloon
EXPERIMENTALTo 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.
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.
