The eSVS® Mesh Post-Marketing Trial

June 28, 2016 updated by: Kips Bay Medical, Inc.

Post-market Study to Evaluate Post-implant Patency Rates of the eSVS Mesh in the Treatment of Saphenous Vein Graphs During Coronary Artery Bypass Grafting Versus Saphenous Vein Grafts Without the eSVS Mesh Via Coronary Angiography and Duplex Ultra-Sonography Results

The purpose of this study is to evaluate patency rates of the eSVS Mesh Saphenous Vein Graph (SVG) and control SVG at six and twenty-four months via coronary angiography and analyses of Duplex Sonography Results and coronary angiography and major cardiovascular or cerebrovascular event (MACCE)-Rate as well as analysis of preoperative great saphenous vein (GSV) duplex sonography and intra-operative GSV harvesting findings and procedure.

Detailed Description

This Study will enroll up to 100 patients total. Patients will be enrolled upon meeting certain inclusion criteria, including GSV duplex-sonography results and consent. They will be enrolled based on their clinically indicated requirement for coronary artery bypass grafting with use of their saphenous vein graft. The study will be prospective, randomized repeated measure controlled trial based on the patient's ability to receive both control and eSVS Mesh treatment. Graft patency, MACCE at 6 and 24 months after meshed and non meshed GSV graft implantation will be measured and the findings and qualification of GSV in preoperative duplex sonography will be compared with intraoperative findings while GSV harvesting in order to evaluate the safety of the eSVS mesh and the role of preoperative GSV duplex sonography.

  • Patient with approximately sized and accessible target coronary arteries, with a minimal diameter of 1.5mm and a lack of severe calcification at the anastomotic site
  • On-pump, off-pump and beating heart (beating heart with cardiopulmonary bypass) CABG.
  • SVG's (eSVS Mesh treated AND non-meshed control vein graft) complying with the size requirements as outlined in the eSVS Mesh "Instructions for Use"
  • CABG operational procedure must allow an eSVS Mesh implant procedure as to the eSVS Mesh Instructions for Use
  • Patients equal to or greater than 21 years of age

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: SVG + eSVS Mesh vs Control SVG
Either the Circumflex Coronary Artery or the Right Coronary Artery will receive the mesh supported vein graft and the native saphenous vein as second and control graft.
Device: eSVS Mesh
Patients with multi-vessel coronary artery disease who require SVG CABG of the Right Coronary Artery and the Circumflex Artery due to atherosclerotic Coronary Artery Disease will serve as their own control. They will be randomized to either an SVG+eSVS Mesh to the RCA and an SVG to the Cx or an SVG to the RCA and an SVG+eSVS Mesh to the Cx.
Other Names:
  • eMesh
  • external saphenous vein support mesh
