Abstract

One embodiment of the present invention provides an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib within a patient, the implantable cardioverter-defibrillator including a housing, wherein at least a portion of the housing is curved; an electrical circuit; and an electrically conductive surface located on a portion of the housing, wherein the electrically conductive surface is coupled to the electrical circuit.

Claims

1. A cardioverter-defibrillator comprising:

an electrode;

a housing having a curved portion, wherein the curved portion of the housing maintains the electrode in a predetermined relationship subcutaneously over a patient'"'"'s ribs; and

a cardioversion-defibrillation circuit located within the housing and coupled to the electrode.

2. The cardioverter-defibrillator of claim 1, wherein the electrode can emit an energy for shocking a patient'"'"'s heart.

3. The cardioverter-defibrillator of claim 2, wherein the electrode can further receive sensory information.

4. The cardioverter-defibrillator of claim 1, wherein the electrode can receive sensory information.

5. The cardioverter-defibrillator of claim 1, wherein at least portion of the electrode is non-planar.
