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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
