Lead for stimulating the baroreceptors in the pulmonary artery
First Claim
1. 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.

Abstract
An apparatus includes a flexible lead body extending from a proximal end to a distal end, an expandable electrode coupled proximate the distal end, the expandable electrode having an expanded diameter dimensioned to abut a wall of a pulmonary artery, and an implantable pulse generator electrically coupled to the expandable electrode. The expandable electrode includes a plurality of electrode zones. The plurality of zones can be tested to determine which zone delivers the best baroreflex response. At least one of the electrode zones can be selected to deliver a stimulation signal based on the testing. The implantable pulse generator is adapted to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode.

14. A method comprising:
-
providing a flexible lead body extending from a proximal end to a distal end with an expandable electrode coupled to the lead body, the expandable electrode comprising a plurality of electrode zones, each electrode zone individually coupled to a separate conductor within the lead body; coupling the expandable electrode to an implantable pulse generator; implanting the expandable electrode in a pulmonary artery proximate a baroreceptor; testing each electrode zone separately to determine which electrode zone delivers the best baroreflex response; selecting at least one of the electrode zones to deliver a baroreflex stimulation signal to the baroreceptor in the pulmonary artery to produce a baroreflex response; and delivering a baroreflex stimulation signal to the baroreceptor in the pulmonary artery via the at least one selected electrode zone, wherein the baroreflex stimulation 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 (15, 16, 17, 18)
