Abstract
Various embodiments of the present subject matter relate to a method. According to various method embodiments, at least one lead is inserted through a pulmonary artery to securely position at least one electrode within the pulmonary artery. Neural stimulation is applied to a neural stimulation target using the at least one lead in the pulmonary artery. An atrial rhythm management activity, including at least one of capturing atrial tissue using the at least one lead and sensing an intrinsic atrial event, is performed using the at least one lead in the pulmonary artery. Other embodiments are provided herein.

20. A lead, comprising:
-
a lead body having an end adapted to connect to an implantable medical device and a distal portion adapted to be securely positioned in a pulmonary artery;
the lead body being adapted to be fed into the right atrium, through a tricuspid valve, into a right ventricle, and through a pulmonary valve; and
the distal portion of the lead body being adapted to be secured within a pulmonary artery, the distal portion including at least one electrode adapted to be positioned within the pulmonary artery when the distal portion is secured within the pulmonary artery, the at least one electrode to be positioned in the pulmonary artery being adapted for use to apply neural stimulation to a neural stimulation target and to provide an atrial rhythm management activity, the atrial rhythm management activity including at least one of capturing atrial tissue and sensing an intrinsic atrial electrical event. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
