Abstract
A cardiac pacing catheter system includes a main guiding catheter and a pair of electrical leads adapted to make direct electrical contact with the ventricle and the atrium of the patient's heart. The main catheter has a pair of lumens which guide and contain the ventricular and atrial leads. Each of the leads can be advanced and manipulated separately and independently within the main catheter body. The lumen for the ventricular lead exits at a port at the distal end of the main catheter body. The lumen for the atrial lead exits along a port at the side of the catheter, at a location proximal of the distal end. The atrial lead is spring-like and is formed with a J-shaped curve at its distal end which, when it exits from the catheter lumen, will assume the J-shaped configuration so that it may be manipulated into direct contact with the more upwardly disposed roof regions of the atrium. The device is used by advancing the catheter, containing the leads in retracted configuration, through the superior vena cava just to the entry to the right atrium. The catheter then can be secured in that position. The ventricular lead then may be extended into and through the right atrium, through…
