Patent ID: 8326436

Claim:
An electrical lead, comprising: a flexible body having a proximal region with a proximal end, and a distal region; a connector coupled to the proximal end of the flexible body of the lead to electrically and mechanically connect the lead to an implantable pulse generator; an inner conductor coil formed from one or more generally cylindrically wound filars having a filar thickness, a pitch and a mean coil diameter configured such that the inner conductor coil has a first inductance value greater than or equal to 0.2 μH/inch when the inner coil conductor lead is subjected to a range of radio frequencies; and a high-voltage multi-filar outer coil having a proximal section, a distal section, and a length, the high-voltage multi-filar outer coil with a direct current (DC) resistance below approximately ten ohms and formed from two or more generally cylindrically wound filars each having a filar thickness, the high-voltage multi-filar outer coil having a pitch, and a mean coil diameter configured such that in the high-voltage multi-filar outer coil has a second inductance value greater than or equal to 0.1 μH/inch when the high-voltage multi-filar outer coil is subjected to the range of radio frequencies.
