Abstract:
A transvenous catheter for insertion into the heart of patient, said catheter suitable for use in combination with a combination atrial and ventricular defibrillator, said catheter comprising:An elongate lead flexibly configured for insertion down the superior vena cava of the heart, into the right atrium, through the opening of the coronary sinus, through the proximal and distal coronary sinus, and into a coronary vein on the surface of the left ventricle of the heart to achieve an operable configuration therein;a first defibrillation electrode connected to said lead;a second defibrillation electrode connected to said lead at a position distal to said first defibrillation electrode; anda third defibrillation electrode connected to said lead at a position distal to said second defibrillation electrode;said first, second, and third defibrillation electrodes spaced apart on said lead so that, when said catheter is in said operable configuration,said first defibrillation electrode is positioned in the proximal coronary sinus of the heart;said second defibrillation electrode is positioned in the distal coronary sinus or great cardiac vein of the heart; andsaid third defibrillation electrode is positioned in a coronary vein on the surface of the left ventricle of said heart.
