1. A method of directing electrical signals from a leadless pacing device received in a distal holding structure attached to a distal end of a delivery catheter, the method comprising:
emitting electrical signals from a first electrode of the leadless pacing device received in the distal holding structure of the delivery catheter;
directing the emitted electrical signals exterior of the distal holding structure through electrical ports in the distal holding structure at a location proximal of the first electrode of the leadless pacing device;
receiving the emitted electrical signals directed exterior of the distal holding structure at a second electrode of the leadless pacing device within the distal holding structure, wherein the second electrode of the leadless pacing device is located distal of the first electrode of the leadless pacing device; and
preventing the emitted electrical signals from traveling from the first electrode to the second electrode within the distal holding structure by providing an electrical barrier positioned within the distal holding structure such that the first electrode is located proximal of the electrical barrier and the second electrode is located distal of the electrical barrier.
