Outcome Measures

Primary Outcomes (1)

  • Restenosis rate of the target lesion

    Subjects receive Digital Subtraction Angiography (DSA) / Computed Tomography Angiography (CTA) examination in 180 days to analyze whether the degree of stenosis is greater than or equal to 50%, if so, the target lesion restenosis happens.

    180+60 days

Secondary Outcomes (3)

  • Average stenosis degree of the target lesion

    180+60 days

  • Success rate of device

    Intraoperation

  • Success rate of surgery

    Intraoperation

Other Outcomes (5)

  • Incidence of device deficiency

    within 180+60 days

  • Incidence of stroke events

    7 days or at discharge / 30±7 days / 180+60 days

  • Rate of death

    7 days or at discharge / 30±7 days / 180+60 days

  • +2 more other outcomes

Study Arms (1)

Group A

EXPERIMENTAL

Neurovascular Drug-Eluting Balloon Dilatation Catheter

Device: Neurovascular Drug-Eluting Balloon Dilatation Catheter

Interventions

The neurovascular drug-eluting balloon dilatation catheter consists of a tip, a drug-coated balloon, markers, a catheter and a catheter hub. The main component of the drug coating is sirolimus, and the coating is evenly distributed on the effective length surface of the balloon.

Group A

  • Creatinine\>250 umol/L;
  • International Normalized Ratio (INR)\>1.5;
  • Female subject who is pregnant or breast-feeding, or who has a pregnancy plan within 12 months;
  • Expected life \<12 months;
  • Unable to cooperate with or tolerate the interventional surgery;
  • Subject who has participated in other drug or device clinical trials or hasn't reached the primary end point;
  • +3 more criteria
