Implantable medical lead using stamped conductor and distal loop

An implantable electrical lead, comprising:

• an elongated insulative lead body having a longitudinal first lumen therein extending from a proximal end of the lead body to a distal portion of the lead body;
• an electrical connector mounted to the proximal end of the lead body;
• and
• an elongated stranded electrical conductor located in the first lumen having a proximal end coupled to the electrical connector and a distal end which exits the lumen at the distal portion of the lead body, which distal end is curved to form a loop exterior to the distal portion of the lead body and which re-enters the lead body;
• and
• wherein strands of the conductor are twisted helically in a first direction and wherein the conductor is twisted in a second, opposite direction in that portion of the conductor located exterior to the lead body to separate strands of the conductor.

An implantable electrical lead system, comprising:

• an elongated insulative lead body having a longitudinal first lumen therein extending from a proximal end of the lead body to a distal portion of the lead body adjacent a distal end of the lead body;
• an electrical connector mounted to the proximal end of the lead body;
• an elongated electrical conductor located in the first lumen, having a proximal end coupled to the electrical connector and a distal end which exits the lumen at the distal portion of the lead body, which distal end is curved to form a loop exterior to the distal portion of the lead body and which reenters the lead body;
• and
• a guidewire, extending through the loop formed by the conductor.
