Abstract

See full text

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. A novel L-C input trap filter is provided which has a dual function. The L-C trap acts as a broadband low pass EMI filter while at the same time also acts as an L-C trap in order to divert induced RF energy from the lead to the housing of the AIMD.
