Catheter and leadless cardiac devices including electrical pathway barrier

A method of directing electrical signals from a leadless pacing device received in a distal holding structure attached to a distal end of a tubular member, the method comprising:

• emitting electrical signals from a first electrode of a leadless pacing device received in a distal holding structure of a delivery catheter;
• directing the emitted electrical signals exterior of the distal holding structure at a first end of the distal holding structure;
• receiving the emitted electrical signals at a second electrode of the leadless pacing device inside a second end of the distal holding structure;
• and
• preventing the emitted electrical signals from traveling from the first electrode to the second electrode within the distal holding structure.

A method of directing electrical signals from a leadless pacing device received in a distal holding structure attached to a distal end of a tubular member, the method comprising:

• emitting electrical signals from a first electrode on a proximal region of a leadless pacing device received in a distal holding structure of a delivery catheter;
• directing the emitted electrical signals proximally through electrical ports in a proximal end of the distal holding structure and exterior of the distal holding structure;
• allowing the emitted electrical signals to travel outside the distal holding structure from the proximal end to a distal end of the distal holding structure;
• receiving the emitted electrical signals at a second electrode of the leadless pacing device inside the distal end of the distal holding structure;
• and
• preventing the emitted electrical signals from traveling from the first electrode to the second electrode within the distal holding structure.
