Methods, devices and systems for cardiac rhythm management using an electrode arrangement
First Claim
1. A method for delivering electrostimulation pulses to a heart using a catheter, the method comprising:
- within a right ventricle of the heart, placing a first electrode facing outward from the distal end of the catheter in physical contact with a septal wall at or near a His Bundle of the heart by attaching the catheter to heart tissue; and
generating at least partially concurrent opposite polarity electrostimulation pulses for delivery at respective electrodes, including at least the first electrode and a second electrode, the electrostimulation pulses sufficient to capture the myocardium of the heart.

Abstract
Various embodiments of the present invention are directed to systems, methods and devices for cardiac applications. One such device is directed to a catheter, and uses thereof, for capturing myocardium of a heart by delivering pacing signals to a location in the heart. The location is near a His Bundle of the heart. The catheter has a proximal end for interfacing with an electrical pacing signal source and a distal end. The distal end includes a fixation mechanism that attaches the catheter to heart tissue. First and second electrodes are also located at the distal end. Each electrode is individually addressable for providing pacing signals to the heart tissue and also arranged to physically contact the heart tissue when the fixation mechanism is attached to the heart tissue.
