Electrode placement apparatus and methods

A medical electrode kit comprising:

• a delivery catheter extending along a catheter axis from a proximal catheter end to a distal catheter end, the delivery catheter comprising a delivery lumen extending from a distal opening at the distal catheter end towards the proximal catheter end;
• a catheter fixation structure located at the distal catheter end, the catheter fixation structure configured to attach the distal catheter end to tissue;
• a first lead assembly located in the delivery catheter lumen, the first lead assembly comprising:
• a push tube comprising a tube lumen extending from a distal tube opening proximally towards a proximal tube end, the push tube located within the delivery lumen extending along the catheter axis, and
• a first lead comprising a first electrode positioned at the distal tube opening and a first conductor attached to the first electrode, the first conductor extending proximally away from the first electrode and towards the proximal tube end;
• and
• a second lead extending from a distal end to a proximal end along a second lead axis, the second lead comprising:
• a second lead body comprising a first lead lumen extending from a lead opening at the distal end of the second lead proximally towards the proximal end of the second lead,
• a lead fixation structure located at the distal end of the second lead, the lead fixation structure configured to attach the distal end of the second lead to tissue, and
• a second electrode exposed on an exterior surface of the second lead body, the second electrode located between the distal end of the second lead and the proximal end of the second lead, wherein the second electrode is configured to be spaced away from tissue to which the lead fixation structure is attached;
• wherein the second lead is configured for advancement over the first conductor of the first lead distally towards the first electrode after the push tube and the delivery catheter are both removed from the first conductor in a proximal direction, and wherein the first conductor is located in the first lead lumen when the second lead is advanced over the first conductor towards the first electrode.
