Abstract:
1. An implantable medical device, comprising: a housing defining an interior cavity; a feedthrough assembly joined to the housing, the feedthrough assembly including at least one conductor to define an energy delivery path; a pulse generator adapted to generate an energy pulse; a control module, within the interior cavity, to regulate the delivery of the energy pulse along the energy delivery path; an EMI filter, located along the energy delivery path, to attenuate electromagnetic interference; and a bypass unit joined to the EMI filter, the bypass unit switching to a closed circuit state, during delivery of the energy pulse, to direct the energy pulse to at least partially bypass the EMI filter, the bypass unit switching to an open circuit state, when the energy pulse is not delivered, to direct EMI signals received at the feedthrough assembly from the at least one conductor through the EMI filter.
