Abstract:
An atrial pacing lead system for accurately locating an atrial pacing electrode in the atrial septum adjacent and substantially above the ostium of the coronary sinus comprising:an atrial pacing lead having an electrode located on a distal portion thereof, anda guide catheter having means for deflecting a distal portion into a serpentine configuration upon deployment that locates a distal end of the catheter proximate the ostium of the coronary sinus and having a longitudinal lumen with an aperture proximal to the distal end of the catheter through which the atrial pacing lead is to be passed and the distal portion of the lead advanced from the aperture to position the electrode in the atrial septum at the desired location wherein the distal portion of said guide catheter includes means for deflecting to form first and second generally planar oppositely directed curves, the second curve being proximal to the first curve, and wherein said lateral aperture is located on an exterior portion of said second curve.
