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.
