1. An apparatus comprising:
- a flexible lead body extending from a proximal end to a distal end, the distal end having a biased portion having an outer diameter dimensioned to abut a wall of a pulmonary artery;
an electrode coupled proximate the distal end; and
an implantable pulse generator electrically coupled to the electrode, wherein the implantable pulse generator is programmed to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode such that the stimulation signal causes a lowering of blood pressure, 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.

Abstract
An apparatus includes a flexible lead body extending from a proximal end to a distal end, the distal end having a biased portion having an outer diameter dimensioned to abut a wall of a pulmonary artery, an electrode coupled proximate the distal end, and an implantable pulse generator electrically coupled to the electrode. The implantable pulse generator is adapted to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode.

17. An apparatus comprising:
-
a flexible lead body extending from a proximal end to a distal end; an electrode coupled to the distal end of the lead body; and an implantable pulse generator electrically coupled to the electrode, the implantable pulse generator being programmed to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode; wherein a biased portion of the distal end is adapted to passively fixate the electrode within the pulmonary artery; wherein the implantable pulse generator is programmed to deliver the baroreflex stimulation signal to the baroreceptor such that the stimulation signal causes a lowering of blood pressure, wherein 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. - View Dependent Claims (18, 19, 20, 21, 22)

23. A method comprising:
-
positioning an electrode on a distal end of a lead within a pulmonary artery, such that the electrode is adjacent a baroreceptor site; and delivering a baroreflex stimulation pulse train to a baroreceptor in the pulmonary artery via the electrode, the pulse train being 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. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method comprising:
-
positioning an electrode on a distal end of a lead within a pulmonary artery, such that the electrode is adjacent a baroreceptor site; and delivering a baroreflex stimulation pulse train to a baroreceptor in the pulmonary artery via the electrode, wherein positioning the electrode includes chronically implanting the electrode proximate the ligamentum arteriosum of the left pulmonary artery, and wherein delivering the baroreflex stimulation pulse train includes delivering a baroreflex stimulation signal to the baroreceptor such that the stimulation signal causes a lowering of blood pressure, wherein 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. - View Dependent Claims (34)
