Method for single elecrode bi-atrial pacing
First Claim
1. A method of implanting an atrial pacing lead, comprising:
- advancing a guide catheter having a longitudinal lumen and a lateral aperture opened to the longitudinal lumen of the catheter proximal to a distal end of the catheter to the ostium of a patient'"'"'s coronary sinus and inserting the distal end of the guide catheter into the coronary sinus such that the lateral aperture of the catheter is located in the patient'"'"'s right atrium;
advancing an atrial pacing lead having an active fixation electrode located on a distal portion thereof through the lumen of the guide catheter such that the active fixation electrode exits the lateral aperture of the guide catheter; and
affixing the electrode to tissue of the atrial septum.

Abstract
An atrial lead system and a method of employing it to provide a single electrode bi-atrial pacing. The system includes an atrial pacing lead having an electrode located on a distal portion thereof and a guide catheter having a longitudinal lumen and a lateral aperture open to the longitudinal lumen of the catheter proximal to a distal end of the catheter through which the distal portion of the lead may be advanced. The electrode is preferably an active fixation electrode or is associated with an active fixation device. The system is employed by first advancing the guide catheter to the ostium of a patient'"'"'s coronary sinus and inserting the distal end of the guide catheter into the coronary sinus such that the lateral aperture of the catheter is located in the patient'"'"'s right atrium. The atrial pacing lead is then advanced through the lumen of the guide catheter such that the electrode exits the lateral aperture of the guide catheter and the electrode is affixed to the tissue of the atrial septum.

4. A method of implanting an atrial pacing lead, comprising:
-
advancing a guide catheter having a longitudinal lumen and a lateral aperture opened to the longitudinal lumen of the catheter proximal to a distal end of the catheter and deflectable to display a first curve located on a distal portion thereof, to the ostium of a patient'"'"'s coronary sinus and inserting the distal end of the guide catheter into the coronary sinus such that the lateral aperture of the catheter is located in the patient'"'"'s right atrium; deflecting the guide catheter to display the first curve; advancing an atrial pacing lead having an active fixation electrode located on a distal portion thereof through the lumen of the guide catheter such that the active fixation electrode exits the lateral aperture of the guide catheter; and affixing the electrode to tissue of the atrial septum. - View Dependent Claims (5)
