Unitary subcutaneous only implantable cardioverter-defibrillator
First Claim
1. An implantable defibrillator comprising an elongated housing having first and second ends and having first and second coil electrodes for delivery of defibrillation energy to a patient disposed on the elongated housing, further comprising therapy delivery circuitry inside the housing coupled to the first and second coil electrodes, said therapy delivery circuit configured to therapeutic energy to a patient by using the first and second coil electrodes as opposing poles for a defibrillation therapy;
- wherein the housing has a length between about 15 to about 50 centimeters and comprises a curve along the length thereof, wherein the housing is malleable and can conform to the chest of a patient such that the curve matches a patient'"'"'s anatomy between the anterior mid-clavicular line and the posterior axillary line; and
wherein the therapy delivery circuitry is configured to deliver the defibrillation therapy with an energy greater than 40 joules and less than 150 joules.

Abstract
A unitary subcutaneous implantable cardioverter-defibrillator that contains a source of electrical energy, a capacitor, and operational circuitry for sensing the presence of potentially fatal heart rhythms. Provided on the housing are cardioversion/defibrillation electrodes located to deliver electrical cardioversion-defibrillation energy when the operational circuitry senses a potentially fatal heart rhythm. The unitary subcutaneous implantable cardioverter-defibrillator does not have a transvenous, intracardiac, epicardial, or subcutaneous electrode.
