Abstract:
1. An implantable medical device which reduces the effects of MRI induced signals, comprising: a canister housing electronic components of the implantable medical device; a medical device electrical lead coupled to at least one of the electronic components of the implantable medical device, wherein an electrically conductive path is defined from the electronic components of the implantable medical device, through the medical device electrical lead and back to the canister housing through a body of a patient; and at least one coil that generates a voltage due to a changing MRI electromagnetic field opposite to a voltage induced on the electrically conductive path from the electronic components of the implantable medical device, through the medical device electrical lead and back to the canister housing through the body of the patient by the changing MRI electromagnetic field so as to reduce the voltage induced on the electrically conductive path from the electronic components of the implantable medical device, through the medical device electrical lead and back to the canister housing through the body of the patient by the changing MRI electromagnetic field.
