摘要：

An implantable medical device includes a coil which is configured for transmission and/or reception of RF fields for communication with external devices. The coil has a conductor that is wound around a core. The core is adapted to saturate in the presence of a static magnetic field or a B0-field generated by an MRI machine thereby reducing the voltage induced in the coil by an RF field and/or by a gradient field generated by the MRI machine.
