Frequency selective passive component networks for active implantable medical devices utilizing an energy dissipating surface
Abstract:
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.
