Unitary subcutaneous only implantable cardioverter-defibrillator and optional pacer
First Claim
1. A unitary subcutaneous implantable cardioverter-defibrillator comprising:
- (A) a long thin housing with a first and second ends that is curved in a shape of a patient'"'"'s rib wherein the housing contains a source of electrical energy, a capacitor, and operational circuitry that senses the presence of potentially fatal heart rhythms;
(B) cardioversion/defibrillation electrodes located at the ends of the housing;
(C) means for delivering electrical cardioversion-defibrillation energy when the operational circuitry senses a potentially fatal heart rhythm; and
(D) the absence of a transvenous, intracardic, epicardial, or subcutaneous electrode.

Abstract
A unitary subcutaneous implantable cardioverter-defibrillator is disclosed which has a long thin housing in the shape of a patient'"'"'s rib. The housing contains a source of electrical energy, a capacitor, and operational circuitry that senses 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, intracardic, epicardial, or subcutaneous electrode.

35. A method of implanting a unitary subcutaneous cardioverter-defibrillator in a patient comprising the steps of;
-
(1) making only one skin incision in the thoracic region of the patient;
(2) inserting a curved introducer through the skin incision to make a subcutaneous path in the thoracic region such that the path terminates subcutaneously at a location that if a straight line were drawn from the skin incision to the path termination the line would intersect the heart of the patient;
(3) implanting a unitary subcutaneous cardioverter-defibrillator that has a long thin housing that is curved in a shape of a patient'"'"'s rib; and
(4) closing the skin incision. - View Dependent Claims (36, 37)
