ABSTRACT:
A temporary cardiac pacing lead is provided with a multiple stranded flexible wire conductor having an insulating coating extending over a major portion of the length of the wire except for an uninsulated terminal forming portion at each end of the wire conductor. A curved needle is attached to one end of the wire conductor and a straight needle is attached to the other end of the wire conductor. The curved needle is passed through the surface of the wall of the heart and is then drawn back out through the surface of the wall so that a portion of one uninsulated terminal forming portion is embedded in the wall and a portion thereof extends out of the wall of the heart. The needle is then passed through a disk-shaped silastic button. The button is moved frictionally on the wire conductor into contact with the surface of the wall of the heart and the portion of the terminal forming portion extending out of the wall is then severed at a position intermediate the needle and the button. The button serves to retain the wire conductor in a fixed position relative to the wall of the heart during stimulation of the heart.
