1. An apparatus comprising:
- an implantable medical device; and
a single pass implantable lead configured to be coupled to the implantable medical device and arranged near or in a left ventricle and left atrium of a patient, the implantable medical lead comprising;
a flexible lead body having a proximal region configured to anchor the flexible lead body against an epicardial surface of a left atrial epicardial wall, a distal region configured to anchor the flexible lead body to a left ventricular epicardial wall, and an adjustable intermediate region between the proximal region and distal region;
at least one proximal electrode arranged in the proximal region of the flexible lead body and configured to sense and pace the left atrium of the patient; and
at least one distal electrode arranged in the distal region of the flexible lead body and configured to sense and pace the left ventricle of the patient.

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 on a left ventricle and left atrium of a patient. The lead may include a proximal region having at least one electrode, a distal region having at least one electrode, and an intermediate region therebetween. The system can sense and pace the left atrium and the left ventricle.

12. A single pass implantable lead comprising:
-
a flexible lead body having a proximal region configured to anchor the flexible lead body against an epicardial surface of a left atrial epicardial wall of a patient, a distal region configured to anchor the flexible lead body to a left ventricular epicardial wall of the patient, and an adjustable intermediate region between the proximal region and distal region, the adjustable intermediate region being configured to configured to mitigate displacement forces to enhance anchoring of the proximal region or distal region; at least one proximal electrode arranged in the proximal region of the flexible lead body and configured to sense and pace the left atrium of the patient; and at least one distal electrode arranged in the distal region of the flexible lead body and configured to sense and pace the left ventricle of the patient. - View Dependent Claims (13, 14, 15, 16)

17. A method of implanting a single pass implantable lead in coronary venous system adjacent to a left ventricle and left atrium of a patient, the method comprising:
-
arranging a proximal region the single pass implantable lead including at least one proximal electrode against the left atrium epicardial wall of the patient; arranging a distal region the single pass implantable lead including at least one distal electrode against the left ventricle epicardial wall of the patient, the single pass implantable lead having an adjustable intermediate region between the proximal region and the distal region; sensing or pacing a cardiac rhythm of the left atrium of the patient via the at least one proximal electrode; and sensing or pacing the left ventricle of the patient via the at least one distal electrode. - View Dependent Claims (18, 19, 20)
