About this study

The WeFlow-Arch Moduler Embedded Aorta Arch Stent Graft System first in man study is a prospective, single center, single arm trial, which will enroll a total of 20 patients. The goal of this study is to evaluate the safety and efficacy of WeFlow-Arch Moduler Embedded Aorta Arch Stent Graft System in the treatment of patients with lesions of the aortic arch.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Experienced systemic infection during past three months;
  • History of aortic valve repair or replacement;
  • History of aortic surgery or endovascular repair surgery;
  • Carotid artery is severely narrowed, calcified, clotted, twisted;
  • Right axillary artery is severely narrowed, calcified, thrombosis, twisted;
  • Heart transplant;

Treatment and study plan

WeFlow-Ach Moduler Embedded Branch Stent Graft System

Device

The modular embedded aortic arch stent graft system consists of the embedded ascending aorta stent graft system, the arch aorta stent graft system and the branch stent system.

Primary outcomes

  1. Rate of no major adverse events related to device or surgery

    Time frame: 30 days after surgery

    Major adverse events related to device or surgery include: stroke, respiratory failure, pericardial tamponade, dissection or aneurysm rupture, paraplegia, stent occlusion, stent bend, stent displacement, thrombosis or rupture of the approach vessel, switch to open surgery, death, etc.

Secondary outcomes

  1. Technical success rate

    Time frame: immediately after the surgery

    Successful delivery of the stent graft conveyors to their predetermined positions, accurate positioning and successful deployment of the stent, safe removal of the delivery device outside the body.

  2. Immediate surgery success rate

    Time frame: immediately after the surgery

    Successful delivery of the stent graft, no major adverse events related to devices or surgery.

  3. The clinical success rate

    Time frame: 12 months after the surgery

    Clinical success rate:12 months after the operation, there was no displacement of the stent, I and III endoleak requiring treatment, aneurysm enlargement or rupture, and branch stent occlusion.

  4. The incidence rate of secondary operations within 12 months after surgery

    Time frame: 12 months after surgery

    The incidence rate of secondary operations within 12 months after surgery.

  5. Adverse event rate within 12 months after surgery

    Time frame: 12 months after surgery

    Adverse event rate within 12 months after surgery.
