Brief Summary:
The purpose of this study is to determine whether or not the Angioshield device can be safely applied to support saphenous vein grafts used in standard coronary bypass surgery.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Angioshield Not Applicable

Detailed Description:
\This is a first in human study which is intended to determine if a larger pivotal study is justified.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 13 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: First-In-Human Study to Demonstrate the Preliminary Safety and Efficacy of the Angioshield System to Provide Mechanical Support for Vein Grafts Used in CABG Surgery
Study Start Date : February 2014
Actual Primary Completion Date : September 2014
Actual Study Completion Date : July 2015

Arm Intervention/treatment
Experimental: Device Applied
All participants will be treated with the Angioshield
Device: 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 Outcome Measures :
  1. MACE [ Time Frame: 30 days ]
    The primary objective of this study is to provide acute and subacute (up to 30 days) safety outcomes to support expansion to a pivotal study involving a larger subject population. All Major Adverse Cardiac Events (MACE), defined as the composite of cardiac death, myocardial infarction (Q-wave and non-Q wave), and target vessel revascularization, will be evaluated at 30 days post-operative.

Secondary Outcome Measures :
  1. MACE and Graft Patency [ Time Frame: 30, 90 and 365 Days ]
    The secondary objective of this study is to assess long term (up to 1 year) safety outcomes and vein patency for additional safety and preliminary efficacy information. All MACE, defined as the composite of cardiac death, myocardial infarction (Q-wave and non-Q wave), and target vessel revascularization will be evaluated at 90 and 365 days and to assess patency of the treated saphenous vein graft at 30, 90 and 365 days
