Implantable cardioverter-defibrillator (ICD) system including substernal lead
First Claim
1. A method comprising:
- detecting a tachycardia with the implantable cardioverter-defibrillator (ICD) system having an ICD and a medical electrical lead, the medical electrical lead having a proximal end coupled to the ICD and a distal portion including one or more electrodes implanted substantially within an anterior mediastinum of a patient such that the one or more electrodes are physically isolated from a pericardium of the patient, wherein the one or more electrodes comprise a defibrillation electrode;
generating an electrical stimulation comprising at least one of a cardioversion shock or a defibrillation shock with the ICD in response to detecting the tachycardia; and
delivering the at least one of the cardioversion shock or the defibrillation shock to a heart of the patient via the defibrillation electrode implanted substantially within the anterior mediastinum of the patient.

Abstract
Substernal implantable cardioverter-defibrillator (ICD) systems and methods for providing substernal electrical stimulation therapy to treat malignant tachyarrhythmia, e.g., ventricular tachycardia (VT) and ventricular fibrillation (VF) are described. In one example, an implantable cardioverter-defibrillator (ICD) system includes an ICD implanted in a patient and an implantable medical electrical lead. The lead includes an elongated lead body having a proximal end and a distal portion, a connector at the proximal end of the lead body configured to couple to the ICD, and one or more electrodes along the distal portion of the elongated lead body. The distal portion of the elongated lead body of the lead is implanted substantially within an anterior mediastinum of the patient and the ICD is configured to deliver electrical stimulation to a heart of the patient using the one or more electrodes.
