An AIMD includes a conductive housing, an electrically conductive ferrule with an insulator hermetically sealing the ferrule opening. A conductive pathway is hermetically sealed and disposed through the insulator. A filter capacitor is disposed on a circuit board within the housing and has a dielectric body supporting at least two active and two ground electrode plates interleaved, wherein the at least two active electrode plates are electrically connected to the conductive pathway on the device side, and the at least two ground electrode plates are electrically coupled to either the ferrule and/or the conductive housing. The dielectric body has a dielectric constant less than 1000 and a capacitance of between 10 and 20,000 picofarads. The filter capacitor is configured for EMI filtering of MRI high RF pulsed power by a low ESR, wherein the ESR of the filter capacitor at an MRI RF pulsed frequency or range of frequencies is less than 2.0 ohms.

An implantable pulse generator system includes a stimulation unit delivering vagal nerve stimulation pulses, an activity sensor determining an exertion level of the user and generating a signal representing metabolic demand, an autonomic tone sensor determining an autonomic status of the user and generating a signal representing autonomic status, and a control unit in communication with the foregoing components, and which is adapted to control the stimulation unit depending on both the signal representing metabolic demand and the signal representing autonomic status.

A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.

A load-carrying body for reducing torsional and tensile loading on electrical components in an implantable medical electrical lead includes an electronic component disposed in-line with the implantable medical electrical lead, and a casing for the electronic component. The electronic component has a proximal end conductively coupled to a lead conductor and a distal end conductively coupled to a lead electrode. The casing is mechanically coupled to the lead so as to isolate the electrical component from torque or tensile loads applied to the lead, the lead electrode, or both.

A nerve cuff stimulation electrode for cervical VNS is provided and configured to be arranged so as to at least partially surround or enclose one of the vagus nerves. The cuff stimulation electrode has at least two contacts configured to deliver electric stimulation pulses to a vagus nerve. The cuff stimulation electrode further has or may be attached or connected to a tilt sensor, a kinematic sensor, and/or a pulsation sensor configured to generate a signal representative of arterial and venous pressures. The implantable tilt sensor is configured to output a posture signal indicating a patient's posture, thus allowing discrimination between supine and semi-recumbent or erect postures.

A composite RF current attenuator for a medical lead includes a conductor having a distal electrode contactable to biological cells, a bandstop filter in series with the lead conductor for attenuating RF currents flow through the lead conductor at a selected center frequency or across a range of frequencies about the center frequency, and a lowpass filter in series with the bandstop filter and forming a portion of the lead conductor. The bandstop filter has a capacitance in parallel with a first inductance. In a preferred form, the lowpass filter includes a second inductance in series with the bandstop filter, wherein the values of capacitance and inductances for the composite RF current attenuator are selected such that it attenuates MRI-induced RF current flow in an MRI environment.

A TANK filter is provided for a lead wire of an active medical device (AMD). The TANK filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the TANK filter is resonant at a selected frequency. In a preferred form, the TANK filter reduces or even eliminates the use of ferro-magnetic materials, and instead uses non-ferromagnetic materials so as to reduce or eliminate MRI image artifacts or the force or torque otherwise associated during an MRI image scan.

A hermetic terminal for an active implantable medical device (AIMD), includes an RF distance telemetry pin antenna, a capacitor conductively coupled between the antenna and a ground for the AIMD, and an inductor electrically disposed in parallel with the capacitor and conductively coupled between the antenna and a ground for the AIMD. The capacitor and the inductor form a band pass filter for attenuating electromagnetic signals through the antenna except at a selected frequency band. Values of capacitance and inductance are selected such that the band pass filter is resonant at the selected frequency band. In an alternative form, the band pass filter is coupled in series with the telemetry pin antenna for attenuating MRI signals of a selected frequency band.
