Patent ID: 7890188

Claim:
A method comprising: providing a lead having a lead body extending from a proximal end to a distal end and having an intermediate portion, the lead having an electrode coupled to the intermediate portion, wherein the distal end of the lead includes a pre-formed, biased shape including a spiral configuration that is configured to passively fixate the pre-formed biased shape of the distal end of the lead within a pulmonary artery; and inserting the lead through a right ventricle and into a pulmonary artery using a guiding catheter or stylet and then removing the guiding catheter or stylet when the pre- formed biased shape is in the pulmonary artery such that the electrode is proximate a ventricular septum or a ventricular outflow tract and the pre-formed biased shape of the distal end is passively fixated within the pulmonary artery.
