A pacing lead having a lead body configured into a pre-formed J-shape. The
lead includes a pacing electrode coupled to an intermediate portion of
the lead body and located distally from a bottom of the pre-formed
J-shape. The lead is adapted to be placed within a heart in a J-shaped
configuration with the electrode positioned proximate a ventricular
septum or a right ventricular outflow tract such that at least a portion
of the distal end of the lead body is located within a pulmonary artery.
In one embodiment, the distal end of the lead is configured to be
passively fixated within the pulmonary artery. Another aspect includes a
lead body wherein a section of the intermediate portion of the lead body
is less stiff than adjacent sections of the lead body. The lead includes
a pacing electrode coupled to the intermediate portion of the lead body
and located distally from the less stiff section. The lead is adapted to
be placed within a heart in a J-shaped configuration with the less stiff
section near a bottom of the J-shape such that the electrode is
positioned proximate a ventricular septum or a right ventricular outflow
tract and at least a portion of the distal end of the lead body is
fixated within a pulmonary artery.
