Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
All participants will be treated with the Angioshield
The Angioshield wrap provides external structural support for the saphenous vein graft used in CABG surgery and is intended to prevent over distention of the graft under arterial pressure, potentially improving graft patency and reducing the likelihood of graft failure.

Primary Outcomes

time frame: 30 days

Secondary Outcomes

MACE and Graft Patency
time frame: 30, 90 and 365 Days

Eligibility Criteria

All participants from 18 years up to 80 years old.

Inclusion Criteria: Subject will be eligible for inclusion in the investigation if he/she: - is between the ages of 18 and 80 years of age, inclusive - requires Coronary Atery Bypass Graft (CABG) surgery with minimum of one SVG used to bypass a stenosis in the Right Coronary, the Circumflex, a Diagonal, or an Obtuse Marginal artery, due to atherosclerotic coronary artery disease - is able to give their informed written consent - is willing and able to complete all follow-up visits and procedures Exclusion Criteria: Subject will be excluded from participation in the investigation if he/she: - is currently enrolled in another clinical investigation - is unable to tolerate or comply with required post-surgical medications or imaging (e.g., anticoagulation regimen; or known allergy to contrast agent) - is or may be pregnant or is lactating, or plans to become pregnant in the next 12 months - shows a presence of hypercoagulable state or history of idiopathic venous or arterial thrombosis - has had an acute MI within the last 21 days - has had a previous CABG - requires emergency surgery - has a left ejection fraction (LEF) less than 20% - has a target vessel stenosis of less than 70% - has a transmural infarct of the target artery territory - currently requiring dialysis - is having concomitant-surgery of any kind - has varicose veins - has had previous saphenectomy
