NCT03509142

Brief Summary

The study is a pilot clinical trial for Sirolimus-eluting Iron Bioresorbable Coronary Scaffold System(IBS). The main purpose of this study is to evaluate the feasibility, preliminary safety and efficacy of IBS. To provide the basis for subsequent large-scale, multi-center, randomized controlled clinical trials of IBS.

Outcome Measures

Primary Outcomes (2)

  • Study Device related Composite Endpoint (Target Lesion Failure)

    Target Lesion Failure is defined as the composited endpoints of including cardiac death, Target vessel related myocardial infarction (TV-MI) and clinical indicated target lesion revascularization (CI-TLR), also known as MACE (major adverse cardiac events).

  • Visual assessment of target lesion stenosis ≥70%, TIMI blood flow≥ 1;
  • Subject who understand the purpose of testing, voluntary and informed consent, patients undergoing invasive imaging follow-up.

You may not qualify if:

  • Patients will be excluded if any of the following conditions apply:
  • General:
  • Within 1 week of any acute myocardial infarction or myocardial enzymes did not return to normal;
  • Implantation of stent in target vessel within 1 year, patients with planned intervention again within six months;

  • Patients had ischemic stroke half a year before implantation, patients had transient ischemic attack 3 months before implantation, patients have high coagulation tendency judged by investigator or laboratory examination;
  • Bleeding, active gastrointestinal ulcers, brain hemorrhage or subarachnoid hemorrhage, contraindications on antiplatelet agents and anticoagulant therapy; patients would not allow to undergoing antithrombotic therapy;
  • Aspirin, clopidogrel, heparin, contrast agent, poly lactic acid polymer, rapamycin and metal allergies;
  • Patients who have a history of disease related to iron overload or iron disorder, such as hereditary hemochromatosis, etc;
  • The patient's life expectancy is less than 12 months;
