Abstract
An intravascular endocardial lead includes an electrically insulated flexible conductor having a lumen throughout the length thereof. A hollow connector element is connected to the proximal end of the conductor, and a hollow elongate electrode is connected to the distal end thereof. A helix assembly is positioned in the electrode and is longitudinally but non-rotatably movable from a retracted position to an extended position. A stylet is inserted through the lumen of the conductor to move the helix assembly to the extended position. Thereafter, when the conductor, electrode and helix assembly are rotated as a unit about the stylet, the helix assembly will penetrate and positively attach the lead to the body tissue and urge the electrode into engagement with the latter.
