Abstract
A body implantable, intravascular lead affixed with a pin or pins at its proximal end adapted to be connected to a pulse generator and with an electrode or electrodes at its distal end adapted to be placed in contact with the endocardium. An electrical conductor(s) encased within a nonconductive material substantially inert to body fluids and tissues electrically connects the electrode(s) with the pin(s) and is comprised of a first length of resilient conductor having a first flexibility and an axial mechanical loading characteristic and a second length of the conductor having a second flexibility greater than the first flexibility and incapable of sustaining the axial mechanical loading characteristic. A dumbbell shaped electrode body provides sufficient size and weight to maintain the distal end of the lead in the apex of the right ventricle.
