Abstract:
Various embodiments concern shielding an implantable lead from RF energy associated with MRI scans. The lead can include a distal region, a proximal region, an intermediate region between the distal region and the proximal region, at least one electrode disposed on the distal region, and at least one conductor extending from the proximal region to the at least one electrode. Implanting of the lead can include coiling a portion of the intermediate region to define one or more loops and selectively shielding the one or more loops of the lead with a RF shield. The RF shield can comprise metallic material and can be configured to reduce RF signal coupling to the at least one conductor along the one or more loops.
