Abstract
An apparatus is provided having at least one fixation electrode adapted to abut a wall of a pulmonary artery, and a pressure sensor integrally supported by the at least one fixation electrode. The pressure sensor provides a signal indicative of a blood pressure in the pulmonary artery. The apparatus also includes a pulse generator coupled with the at least one fixation electrode, the pulse generator adapted to deliver a baroreflex stimulation signal to one or more baroreceptors in the pulmonary artery via the at least one fixation electrode. The pressure sensor is anchorable in the pulmonary artery via the at least one fixation electrode.
Claims26
An apparatus comprising:
- at least one fixation electrode adapted to abut a wall of a pulmonary artery;
- a pressure sensor integrally supported by the at least one fixation electrode, the pressure sensor providing a signal indicative of a blood pressure in the pulmonary artery;
- a pulse generator coupled with the at least one fixation electrode, the pulse generator adapted to deliver a baroreflex stimulation signal to one or more baroreceptors in the pulmonary artery via the at least one fixation electrode;
- and wherein the pressure sensor is anchorable in the pulmonary artery via the at least one fixation electrode.
An apparatus comprising:
- an expandable electrode having an expanded diameter dimensioned to abut a wall of a pulmonary artery;
- a pulmonary artery pressure sensor coupled to the expandable electrode, the pressure sensor adapted to monitor blood pressure in the pulmonary artery;
- a pulse generator electrically coupled with the expandable electrode, the pulse generator being adapted to deliver a baroreflex stimulation signal to a baroreceptors in the pulmonary artery by way of the expandable electrode;
- and wherein the expandable electrode is adapted to fix the pulmonary artery pressure sensor in place by frictional forces.
A method comprising:
- forming an expandable electrode, including forming an expanded shape dimensioned to abut a wall of a pulmonary artery;
- securing a pulmonary artery pressure sensor to the expandable electrode such that the pressure sensor is fixable in the pulmonary artery via the expandable electrode;
- and wherein the expandable electrode and the pulmonary artery pressure sensor are adapted to be fed through a right ventricle and a pulmonary valve into the pulmonary artery.
A method of use comprising:
- implanting an expandable electrode having an integrated pressure sensor within a pulmonary artery such that an outer surface of the electrode abuts a wall of the pulmonary artery;
- monitoring a signal indicative of a blood pressure in the pulmonary artery using the pressure sensor;
- and delivering a baroreflex stimulation signal to one or more baroreceptors in the pulmonary artery via the electrode.
