Abstract
An implantable multi-conductor endocardial lead for a cardiac stimulator includes a tubular lead body of flexible resilient insulative material having a first lumen and a smaller diameter tubular member of similar material having a second lumen is coaxially received in the first lumen. An outer coil conductor is received within an annular cavity between the tubular lead body and the tubular member. An elongated inner coil conductor is received within the second lumen. A tip electrode at the distal end of the lead is coupled to the inner coil conductor and a ring electrode proximally spaced from the tip electrode is coupled to the outer coil conductor. All components except for the outer coil conductor have a normally straight configuration and the outer coil conductor is pre-shaped into a generally circular looped configuration such that, upon assembly, the resulting endocardial lead results in a J-configuration at its distal end.
