Abstract
A method of inserting a pacing lead having a preformed shape into a coronary sinus to pace the left atrium includes providing a lead having an elongated body and proximal and tip sections. The sections are configured such that a first angle less than 90 degrees is defined between the lead body and proximal section and a second angle is defined between the tip and proximal sections. The method further comprises advancing the pacing wire towards the opening of the coronary sinus and advancing the wire into the coronary sinus, such that the first angle is compressed by the coronary sinus opening and a tip electrode included on the tip section contacts the wall of the coronary sinus near the left atrium operably extending the second angle to assure constant contact between the wall of the coronary sinus and the tip electrode.
