摘要:
A medical device lead includes a conductor and one or more band stop filters. The conductor extends through a lead body and includes a proximal end and a distal end. The one or more band stop filters each have a first end and a second end and include a conductive coil. At least one of the first end and second end of each band stop filter is coupled to the conductor. A length of each band stop filter is such that, at magnetic resonance imaging (MRI) frequencies, the band stop filter phase shifts an MRI-induced signal on the conductor by 180° to attenuate the MRI-induced signal on the conductor.
