简要总结
Feasibility Study to Demonstrate the Safety of the Angioshield System to Provide Mechanical Support for Vein Grafts Used in CABG Surgery.
详细描述
The study is designed to investigate the feasibility of using an applied support (Angioshield) to a saphenous vein to be used in Coronary Artery Bypass Surgery. It is a feasibility to determine safety prior to launching a larger pivotal study. The primary endpoint, 30-day safety, will be assessed by recording and reporting of adverse events during surgery and throughout the investigation until the 30-day follow-up visit. The secondary endpoints, long term safety and patency, will be assessed by recording and reporting of adverse events and graft patency (via serial CT angiograms) at the 30, 90, and 365 day follow-up visits.

结局指标
主要结局
Safety-reported MACE
时间窗: 30 days
The primary endpoint, 30 day safety, (MACE) will be assessed by recording and reporting of adverse events during surgery and throughout the investigation until the 30-day follow-up visit
次要结局
- Safety, (MACE) will be assessed by recording and reporting of adverse events at the 30, 90, and 365 day follow-up visits.(90 and 365 days)
- Patency: Graft patency (via serial CT angiograms) will be measured at the 30, 90, and 365 day follow-up visits.(30, 90 ,and 365 days)
