Abstract

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 at least one electrically conductive surface integrally positioned on at least one portion of the house, wherein at least one electrically conductive surface is coupled to the electrical circuit.

Claims

1. An implantable cardioverter-defibrillator comprising:

a housing comprising a mixture of conductive and non-conductive materials;

an electrode disposed on the housing; and

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

2. The implantable cardioverter-defibrillator of claim 1, wherein the housing comprises a mixture of ceramic materials and titanium.

3. The implantable cardioverter-defibrillator of claim 1, wherein the electrode is integrally positioned on a portion of the housing.

4. The implantable cardioverter-defibrillator of claim 1, wherein at least a portion of the housing is curved.

5. The implantable cardioverter-defibrillator of claim 1, wherein the electrode is a subcutaneous electrode that is adapted to emit energy for treating the patient'"'"'s heart from a subcutaneous position within the patient.

6. The implantable cardioverter-defibrillator of claim 5 wherein the electrode is further adapted to receive sensory information.

7. The implantable cardioverter-defibrillator of claim 1, wherein the electrode is adapted to receive sensory information.

8. The implantable cardioverter-defibrillator of claim 1, wherein the implantable cardioverter-defibrillator is adapted for subcutaneous positioning between the third rib and the twelfth rib within a patient.

9. An implantable cardioverter-defibrillator comprising:

a housing for subcutaneous implantation within a patient, the housing comprising a mixture of conductive and nonconductive materials;

a subcutaneous electrode disposed on the housing; and

cardioversion-defibrillation circuitry located within the housing and coupled to the subcutaneous electrode.

10. The implantable cardioverter-defibrillator of claim 9, wherein the housing comprises a mixture of ceramic materials and titanium.

11. The implantable cardioverter-defibrillator of claim 9, wherein the housing is sized and shaped for subcutaneous positioning between the third rib and the twelfth rib within the patient.

12. The implantable cardioverter-defibrillator of claim 9, wherein the subcutaneous electrode is positioned on the housing such that when the housing is subcutaneously implanted within the patient, the electrode is maintained in a predetermined subcutaneous position relative to the patient'"'"'s heart.

13. The implantable cardioverter-defibrillator of claim 9, wherein the subcutaneous electrode is adapted to emit energy for treating a patient'"'"'s heart from a subcutaneous position within the patient.

14. The implantable cardioverter-defibrillator of claim 13, wherein the electrode is further adapted to receive sensory information.

15. The implantable cardioverter-defibrillator of claim 9, wherein the subcutaneous electrode receives sensory information.

16. The implantable cardioverter-defibrillator of claim 9, wherein the subcutaneous electrode is integrally positioned on a portion of the housing.

17. An implantable cardioverter-defibrillator comprising:

a housing comprising a mixture composition including both conductive and nonconductive materials;

an electrical circuit located within the housing; and

an electrode disposed on a portion of the housing, wherein the electrode couples to the electrical circuit.

18. The cardioverter-defibrillator of claim 17, wherein the mixture composition comprises a mixture of ceramic and titanium.

19. A method of making an implantable cardioverter-defibrillator, the method comprising:

providing a housing comprising a mixture of conductive and non-conductive materials;

disposing an electrode on the housing;

disposing a cardioversion-defibrillation circuitry within the housing; and

coupling the cardioversion-defibrillation circuitry to the electrode.

20. The method of claim 19, wherein providing a housing includes providing a housing for subcutaneous implantation within a patient, and wherein the electrode is a subcutaneous electrode.

21. The method of claim 19, wherein disposing the electrode includes integrally positioning the electrode on a portion of the housing.

22. A method of providing therapy to a patient, the method comprising:

providing a subcutaneously implantable cardioverter-defibrillator, the implantable cardioverter-defibrillator including a housing comprising a mixture of conductive and non-conductive materials, a subcutaneous electrode disposed on the housing, and a cardioversion-defibrillation circuitry disposed within the housing and coupled to the electrode; and

subcutaneously implanting the housing between the third rib and the twelfth rib within the patient such that the electrode is maintained in a predetermined subcutaneous position relative to the patient'"'"'s heart.
