Abstract:
1. An in vivo medical stimulation probe, comprising: an elongate lead having a length and at least one stimulation electrode disposed on a distal portion thereof, at least one axially exending conductor coupled to the at least one stimulation electrode, and an axially extending shielding layer surrounding the at least one conductor over at least a major length of the lead and terminating at a lead location that is in advance of the at least one stimulation electrode; a plurality of RF chokes axially spaced apart along the length of the lead and disposed on and/or in the shielding layer in advance of the at least one electrode to inhibit induced RF current from forming and/or traveling along the shielding layer; and an MRI antenna that is configured to collect and transmit signal data in response to an applied RF excitation pulse in an MRI scanner system, wherein the lead is MRI-compatible.
