摘要： An energy management system that facilitates the transfer of high frequency energy induced on an implanted lead or a leadwire includes an energy dissipating surface associated with the implanted lead or the leadwire, a diversion or diverter circuit associated with the energy dissipating surface, and at least one switch for diverting energy in the implanted lead or the leadwire through the diversion circuit to the energy dissipating surface. In alternate configurations, the switch may be disposed between the implanted lead or the leadwire and the diversion circuit, or disposed so that it electrically opens the implanted lead or the leadwire when diverting energy through the diversion circuit to the energy dissipating surface. The switch may comprise a single or multi-pole double or single throw switch. The diversion circuit may be either a high pass filter or a low pass filter.

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： The invention describes a system, method, and means for an MRI transseptal needle that can be visible on an MRI, can act as an antenna and receive MRI signals from surrounding subject matter to generate high-resolution images and can enable real-time active needle tracking during MRI guided transseptal puncture procedures.
