简要总结
Evaluate the safety and efficacy of the Timing Carotid Stent for the treatment of carotid artery stenosis in patients.
详细描述
This is a prospective, randomized, concurrent controlled, multi-center study. Patients with carotid artery stenosis will be assigned to either the Timing Carotid Stent or Carotid Wallstent. Each treated patient will be followed and assessed for 12 months after randomization. The hypothesis to be tested is that the safety and effectiveness of the Timing Carotid Stent is not inferior to the Carotid Wallstent.
