Pericardial lead

An implantable medical system, comprising:

• a pulse generator configured to detect arrhythmias and provide therapy;
• a medical lead configured to be coupled to the pulse generator and implanted proximate to a pericardium of a patient heart, the implantable medical lead comprising:
• a lead body including a distal end and a proximal end;
• a defibrillator electrode disposed distal on the lead body and configured to deliver an electrotherapy;
• a proximal lead portion coupled to and proximally disposed from the defibrillator electrode, the proximal lead portion including a nonconductive proximal curved section;
• a proximal electrode disposed proximally to the defibrillator electrode and configured to provide at least one of pacing or sensing;
• a distal lead portion coupled to and distally disposed from the defibrillator electrode, the distal lead portion including a nonconductive distal curved section disposed between the distal end and the defibrillator electrode;
• and
• a tip electrode disposed on the distal end of the lead body and configured to provide at least one of pacing or sensing,
• wherein the proximal curved section and distal curved section are self-biasing when not acted upon by an outside force to form a curved shape in the lead body to bias the defibrillation electrode against the pericardium.
