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 electrically connected via conductor means and adapted to be securely and permanently attached to a body organ. Electrode means in the form of an elongated member having a circumferential electrode formed on one end thereof and an opening passing therethrough from its proximal to distal end is affixed to the distal end of the conductor means. Tissue securing means extending beyond the opening in the distal end of the electrode means are provided for securing the electrode means into firm engagement with the tissue at the desired location. Movable means located in the opening in the electrode means are provided for protecting the tissue securing means from causing injury to a body vessel, heart valve, or other tissue as the lead is inserted and guided through a vessel to the desired location. Various types of stylet means may be used to move the movable means into the position for protecting the tissue securing means.
