Systems for using a pulmonary artery electrode
First Claim
1. A system comprising an implantable medical device (IMD) and a lead configured to be connected to the IMD, the lead comprising:
- a lead body having an end adapted to connect to the IMD 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, wherein the IMD is adapted to use the at least one electrode to;
apply neural stimulation to a neural stimulation target when the distal portion is secured within the pulmonar artery; and
capture atrial tissue when the distal portion is secured within the pulmonary artery, or sense an intrinsic atrial electrical event when the distal portion is secured within the pulmonary artery, or both capture atrial tissue and sense an intrinsic atrial electrical event when the distal portion is secured within the pulmonary artery.

Abstract
According to some method embodiments, a left pulmonary artery electrode is positioned in a left pulmonary artery, and the left pulmonary artery electrode is used to sense atrial activity, or capture cardiac tissue, or deliver neural stimulation. According to some method embodiments, a right pulmonary artery electrode is positioned in a right pulmonary artery and a left pulmonary artery electrode is positioned in a left pulmonary artery, the right pulmonary artery electrode is used to sense atrial activity, or capture cardiac tissue, or deliver neural stimulation, and the left pulmonary artery electrode is used to sense atrial activity, or capture cardiac tissue, or deliver neural stimulation.
