Patent ID: 8473076

Claim:
A method comprising: implanting an expandable electrode within a pulmonary artery such that an outer surface of the expandable electrode abuts a wall of the pulmonary artery, the expandable electrode comprising a plurality of electrode zones, each zone individually coupled to a separate conductor of the lead body; testing each of the electrode zones to determine which zone delivers the best baroreflex response; selecting at least one of the electrode zones based on the testing; and delivering a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the one or more selected electrodes, wherein the implantable pulse generator is programmed such that the signal is delivered for about 5 seconds to about 10 seconds each minute at a voltage of about 0.1 volts to about 10 volts and a frequency of about 10 Hz to 150 Hz.
