Implantable cardioverter-defibrillator (ICD) system including substernal pacing lead
First Claim
1. A method comprising:
- generating one or more pacing pulses with an implantable cardiac device;
delivering the one or more pacing pulses via at least one electrode of a pacing lead coupled to the implantable cardiac device and implanted at least partially along a posterior side of a sternum within an anterior mediastinum of a patient such that the at least one electrode is physically isolated from a pericardium of the patient, wherein the pacing lead comprises a first elongated body defining at least one lumen therethrough;
generating a defibrillation pulse with the implantable cardiac device; and
delivering the defibrillation pulse via at least one electrode of a defibrillation lead coupled to the implantable cardiac device, wherein the defibrillation lead comprises a second elongated body, separate from the first elongated body, defining at least one lumen therethrough.

Abstract
An implantable cardiac defibrillator (ICD) system includes an ICD implanted subcutaneously in a patient, a defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation or cardioversion shock to a heart of the patient, and a pacing lead that includes a distal portion having one or more electrodes and a proximal portion coupled to the ICD. The distal portion of the pacing lead is implanted at least partially along a posterior side of a sternum of the patient within the anterior mediastinum. The ICD is configured to provide pacing pulses to the heart of the patient via the pacing lead and provide defibrillation shocks to the patient via the defibrillation lead. As such, the implantable cardiac system provides pacing from the substernal space for an extravascular ICD system.
