Abstract: A filter feedthrough is described. The filter feedthrough includes a conductive ferrule supporting a dielectric substrate having a body fluid side and a device side. At least one via hole provided with a conductive fill is disposed through the dielectric substrate from the body fluid side to the device side. At least one MLCC-type capacitor is supported by the dielectric substrate. A first circuit trace couples from an active metallization connected to the active electrode plates of the capacitor to conductive fill in the via hole. A second circuit trace couples from the ground electrode plate of the capacitor to a metallization contacting an outer surface of the dielectric substrate. Then, a conductive material couples from the ground metallization to the ferrule to thereby electrically couple the capacitor to the ferrule.

A conductor is hermetically sealed to and disposed through the insulator. A filter capacitor has an active electrode plate and a ground electrode plate which are disposed within and supported by a capacitor dielectric in an interleaved, partially overlapping relationship. A first passageway is disposed through the capacitor dielectric having a capacitor internal metallization which is connected to the active electrode plate. A capacitor external metallization electrically connects to the ground electrode plate. An oxide-resistant metal addition includes a conductive core with a conductive cladding of a different material. A first electrical connection is between the oxide-resistant metal addition and the capacitor external metallization. A second electrical connection is between the oxide-resistant metal addition and the ferrule.

Abstract: An implantable cardioverter defibrillator (ICD) includes a communication interface operable to receive a communication signal from an external programmer. With the ICD not being in the presence of an MRI field generated by an MRI scanner, a communication signal is sent precharging a high energy storage capacitor before the patient undergoes the MRI scan. The signal also switches the ICD into an MRI mode which turns off the ICD's sensing functions detecting a dangerous ventricular arrhythmia. An operator monitors the patient's vital signs with sensors connected to the patient. If the patient does require the defibrillation shock, the operator sends a second communication signal delivering the defibrillation shock from the precharged high energy storage capacitor of the ICD. The patient can then be removed from the MRI scanner and the RF and gradient fields of the MRI scanner turned off.

Abstract: A shielded component or network for an active medical device (AMD) implantable lead includes (1) an implantable lead having a length extending from a proximal end to a distal end, all external of an AMD housing, (2) a passive component or network disposed somewhere along the length of the implantable lead, the passive component or network including at least one inductive component having a first inductive value, and (3) an electromagnetic shield substantially surrounding the inductive component or the passive network. The first inductive value of the inductive component is adjusted to a account for a shift in its inductance to a second inductive value when shielded.
