1. A method of implanting a subcutaneous cardioverter-defibrillator in a patient, the method comprising:
- providing a subcutaneously implantable cardioverter-defibrillator including an electrically active canister that serves as either an anode or a cathode of the cardioverter-defibrillator, wherein the canister houses a source of electrical energy, a capacitor, and operational circuitry, and the cardioverter-defibrillator further includes a subcutaneous lead connected to the canister, the lead including a subcutaneous cardioversion-defibrillation electrode that serves as the opposite electrode from the canister such that electrical cardioversion-defibrillation energy is delivered between the subcutaneous electrically active canister and the subcutaneous cardioversion-defibrillation electrode;
inserting the subcutaneous canister in a predetermined subcutaneous position within the thorax of the patient;
inserting the subcutaneous lead in a predetermined subcutaneous path extending around a portion of the thorax of the patient so that the cardioversion-defibrillation electrode is positioned such that electrical cardioversion-defibrillation energy is delivered to the heart of the patient when electrical cardioversion-defibrillation energy is delivered between the subcutaneous electrically active canister and the subcutaneous cardioversion-defibrillation electrode.

Abstract
A subcutaneous implantable cardioverter-defibrillator which has an electrically active canister which houses a source of electrical energy, a capacitor, and operational circuitry that senses the presence of potentially fatal heart rhythms delivers cardioversion defibrillation energy between at least one subcutaneous lead and the electrically active canister. There are no transvenous, intracardiac, or epicardial electrodes. The electrically active canister and at least one lead is implanted utilizing a curved introducer to implant the electrically active canister subcutaneously at various locations around the thorax.

4. A method of providing anti-arrhythmia therapy to a patient having a heart, the method comprising:
-
providing a subcutaneous implantable cardioverter-defibrillator including a subcutaneous electrically active canister that serves as either an anode or a cathode of the cardioverter-defibrillator, wherein the canister houses a source of electrical energy, a capacitor, and operational circuitry, the cardioverter-defibrillator further including a subcutaneous lead connected to the canister, the lead including a subcutaneous cardioversion-defibrillation electrode spaced from the canister that serves as the opposite electrode from the canister; inserting the subcutaneous canister in a predetermined subcutaneous position within the thorax of the patient; inserting the subcutaneous lead in a predetermined subcutaneous path extending around a portion of the thorax of the patient such that the cardioversion-defibrillation electrode is positioned at a subcutaneous location spaced from the canister; and delivering electrical cardioversion-defibrillation energy to the heart of the patient between the subcutaneous electrically active canister and the subcutaneous cardioversion-defibrillation electrode. - View Dependent Claims (5, 6)
