Abstract
A lead body includes an electrode coupled to an intermediate portion of the lead body. A distal end of the lead includes a pre-formed, biased shape adapted to passively fixate the distal end of the lead within a pulmonary artery with the electrode positioned in the right ventricle or ventricular outflow tract. The lead body can include a preformed J-shape, with the electrode coupled to the intermediate portion of the lead body and located distally from a bottom of the pre-formed J-shape. The lead body can include a section of the intermediate portion of the lead body being less stiff than adjacent sections of the lead body with the electrode coupled to the intermediate portion of the lead body and located distally from the less stiff section.
