Annular Reshaping of the Mitral Valve for Patients With Mitral Regurgitation Using the Millipede IRIS System
Annular Reshaping of the Mitral Valve for Patients With Mitral Regurgitation Using the Millipede IRIS System
Multi center evaluation of the Millipede IRIS for treatment of clinically significant mitral
 regurgitation in subjects determined appropriate for mitral valve surgery.
Multi center evaluation of the Millipede IRIS for treatment of clinically significant mitral
 regurgitation in subjects determined appropriate for mitral valve surgery.

 This trial is designed in accordance with the 2014 ACC/AHA guidelines for valvular heart
 disease, and the consensus statement of MVARC 2015.

 Subjects will undergo transcatheter implantation of the Millipede IRIS implant.
