摘要： Decoupling circuits are provided which transfer energy induced from an MRI pulsed RF field to an energy dissipating surface. This is accomplished through broadband filtering or by resonant filtering. In a passive component network for an implantable leadwire of an active implantable medical device, a frequency selective energy diversion circuit is provided for diverting high-frequency energy away from a leadwire electrode to a point or an area spaced from the electrode, for dissipation of high-frequency energy.

摘要： Decoupling circuits are provided which transfer energy induced from an MRI pulsed RF field to the housing for an active implantable medical device (AIMD) which serves as an energy dissipating surface. This is accomplished through broadband filtering or by resonant filtering. In a passive component network for an AIMD, a frequency selective energy diversion circuit is provided for diverting high-frequency energy away from an AIMD lead to the AIMD housing for dissipation of said high-frequency energy.

摘要： A bandstop filter includes a capacitance in parallel with an inductance and is placed in series with the implantable lead of an active implantable medical device, wherein values of capacitance and inductance are selected such that the bandstop filter attenuates RF current flow at a selected center MRI RF pulsed frequency or across a range of frequencies. The Qi of the inductor and the Qc of the capacitor are controlled to reduce the overall Q of the bandstop filter to attenuate current flow through the implantable lead along a range of selected frequencies. In a preferred form, the bandstop filter is integrated into a Tip and/or Ring electrode for the active implantable medical device.

摘要： Medical lead systems utilizing electromagnetic bandstop filters are provide which can be utilized in a magnetic resonance imaging (MRI) environment for patients who have implanted medical devices. The medical lead system includes an implanted lead having at least one bandstop filter associated therewith, for attenuating current flow through the lead over a range of frequencies. The bandstop filter has an overall circuit Q wherein the resultant 3 dB bandwidth is at least 10 kHz. The values of capacitance and inductance of the bandstop filter are selected such that the bandstop filter is resonant at a selected center frequency. Preferably, the bandstop filter has an overall circuit Q wherein the resultant 10 dB bandwidth is at least 10 kHz. Such bandstop filters are backwards compatible with known implantable deployment systems and extraction systems.

摘要： 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.

摘要： A shielded three-terminal flat-through EMI/energy dissipating filter includes an active electrode plate through which a circuit current passes between a first terminal and a second terminal, a first shield plate on a first side of the active electrode plate, and a second shield plate on a second side of the active electrode plate opposite the first shield plate. The first and second shield plates are conductively coupled to a grounded third terminal. In preferred embodiments, the active electrode plate and the shield plates are at least partially disposed with a hybrid flat-through substrate that may include a flex cable section, a rigid cable section, or both.
