SINGLE PASS CORONARY VENOUS LEAD FOR MULTIPLE CHAMBER SENSE AND PACE
First Claim
1. A method of pacing a patient'"'"'s heart using an implantable lead having a proximal region including at least one proximal electrode positioned in a coronary sinus or great cardiac vein of the patient'"'"'s heart and a distal region positioned in a coronary vein of the patient'"'"'s heart such that at least one of a plurality of distal electrodes is situated proximate an intraventricular septum of the patient'"'"'s heart, the method comprising:
- sensing an atrial and a ventricular signal of the patient'"'"'s heart via at least one of the proximal electrodes and one of the distal electrodes, respectively;
determining a pacing threshold associated with each of the plurality of distal electrodes;
selecting at least one of the plurality of distal electrodes that have associated therewith right and left ventricular pacing thresholds; and
delivering a pacing signal to the patient'"'"'s heart via the selected at least one distal electrode, the transmitted pacing signal causing a desired contraction of both the right ventricle and the left ventricle.

Abstract
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a single pass implantable lead configured to be coupled to the implantable medical device and arranged to sense and pace the chambers of a patient'"'"'s heart. The lead may include a proximal region having a plurality of electrodes, a distal region having at least one electrode, and an intermediate region therebetween. The system can sense and pace the right atrium, the left atrium, the right ventricle, and the left ventricle.

13. A method of inserting an implantable lead into a patient'"'"'s heart, the implantable lead having a proximal region including a plurality of proximal electrodes and a distal region including at least one distal electrode, the method comprising:
-
inserting the implantable lead into the patient'"'"'s heart via a superior vena cava or an inferior vena cava; positioning the implantable lead such that at least a portion of the proximal region of the single pass implantable lead is positioned within a coronary sinus of the patient'"'"'s heart and at least a portion of the distal region of the single pass implantable lead is positioned within an anterior coronary vein, with the at least one distal electrode being positioned adjacent to an intraventricular septum of the patient'"'"'s heart; electrically connecting the single pass implantable lead to a pulse generator or an implantable medical device; selecting a first proximal electrode from the plurality of proximal electrodes to operate as a right atrial pacing electrode based on a measured right atrial pacing threshold associated with the first proximal electrode; selecting a second proximal electrode from the plurality of proximal electrodes to operate as a left atrial pacing electrode based on a measured left atrial pacing threshold associated with the second proximal electrode; and selecting a first distal electrode from the at least one distal electrode to operate as a right ventricular and left ventricular pacing electrode based on measured right and left ventricular pacing thresholds associated with the first distal electrode. - View Dependent Claims (15, 16, 17, 18)

19. A method of performing biventricular pacing of a patient'"'"'s heart using an implantable lead, the method comprising:
-
positioning a proximal region of the implantable lead such that one or more proximal electrodes are positioned in a coronary sinus or the great cardiac vein of the patient'"'"'s heart; positioning a distal region of the implantable lead in an anterior coronary vein of the patient'"'"'s heart such that one or more distal electrodes are situated adjacent to an intraventricular septum of the patient'"'"'s heart; sensing an atrial and a ventricular signal of the patient'"'"'s heart via one or more of the proximal electrodes and distal electrodes; selecting at least one distal electrode having associated therewith right and left ventricular pacing thresholds below a designated pacing threshold; delivering, via a pulse generator coupled to the implantable lead, a pacing signal to the patient'"'"'s heart via the selected at least one distal electrode, the delivered pacing signal causing a desired contraction of both the right ventricle and the left ventricle. - View Dependent Claims (20)
