1. A method of securing an implantable medical device on an epicardial surface, the method comprising:
passing a sheath into a pericardial space of a patient through a first percutaneous access site;
passing a guidewire comprising a first end and a second end through the sheath into the pericardial space of the patient;
passing the guidewire through a transverse sinus of the patient;
passing a snare device into the pericardial space through a second percutaneous access site;
capturing a free end portion of the guidewire using the snare device;
threading the implantable medical device over the guidewire to be positioned near the epicardial surface; and
securing the first end and the second end of the guidewire to a hole, a slot, or a notch defined by a cap configured to abut an apex of a heart of the patient such that the guidewire forms a loop that begins and ends at the cap,
wherein the guidewire comprises one or more denuded portions that are configured to function as one or more electrodes, and
wherein the implantable medical device comprises a defibrillator coil.
