We have created an active MRI-compatible delivery cable incorporating a loopless antenna that enables greater visualization of the occlusion device during percutaneous delivery and deployment of the device under MRI. During in vivo use, deployment and positioning of the occlusion device in the ventricular septum was apparent with the increased signal provided by the active delivery system. The device appearance provided by this active delivery cable combined with the superior soft-tissue visualization of MRI makes the treatment of a wide range of structural heart disease under MRI guidance feasible and promising.
