The purpose of this study is to evaluate the safety and feasibility of the Bio Refine Coriofix System and determine if it might help in treatment of functional mitral regurgitation. The study will include patients with symptomatic secondary mitral regurgitation in whom mitral surgery cannot and/or will not be offered as a treatment option (the risk is prohibitive). Potential patients will be screened to confirm that all inclusion/exclusion criteria are met, with final eligibility confirmation on day of procedure. All enrolled subjects who went through the procedure will be followed during the procedure to hospital discharge. Additional follow up time points are scheduled at 30 days, 6 months and 12 months post procedure.
