ABSTRACT:
A bi-polar coaxial cable or catheter is passed transvenously into or proximate the heart, and the electrodes or poles of the cable are so positioned to apply electrical energy to the heart for defibrillation. Electrical energy input to the cable to effect defibrillation is in the form of a Lown wave. The invention also relates to a defibrillation method. A tri-axial cable catheter may be used for detecting fibrillation condition, defibrillation, and pacemaker functions. As space provides in the vein, additional leads may be included in the transvenous catheter for further monitoring and/or signal injecting purposes; and such leads may be of coaxial design. Further, as space provides, the catheter may include a hollow portion through which medicament may be conducted from outside the body directly into the heart and/or direct reading of central venous pressure may be effected.
