Abstract

Intracardiac devices that can provide a plurality of functions (e.g., pacing, defibrillation, cardiac assist, or valve replacement) via a single support member and control means.

Claims

1. An apparatus comprising an elongate support member having a first end and a second end, a controlling means positioned at said first end and an anchor means positioned at said second end, and two or more intracardiac devices positioned on or in said elongate support member between said first end and said second end, wherein said anchor means is adapted for attachment to the myocardium, and wherein said controlling means is adapted to control the action of said two or more intracardiac devices.

2. The apparatus of claim 1, wherein said two or more intracardiac devices are selected from the group consisting of valves, implantable cardioverter defibrillator (ICD) coils, balloons, micro pumps, and piezoelectric elements.

3. The apparatus of claim 1, wherein said two or more intracardiac devices comprise a first balloon and a second balloon, wherein said first balloon is adapted for placement at about the location of a cardiac valve, and wherein said second balloon is adapted for placement in the ventricle distal to said cardiac valve.

4. The apparatus of claim 3, wherein said cardiac valve is a mitral valve.

5. The apparatus of claim 1, wherein said two or more intracardiac devices comprise a valve and an ICD coil.

6. The apparatus of claim 5, wherein said ICD coil is distal to said valve.

7. The apparatus of claim 5, further comprising one or more electrodes on the circumference of said valve.

8. The apparatus of claim 1, wherein said two or more intracardiac devices comprise a valve and a balloon.

9. The apparatus of claim 8, wherein said balloon is distal to said valve and is adapted for placement within a ventricle.

10. The apparatus of claim 1, wherein said two or more cardiac devices comprise a mesh-like, conical-shaped valve.

11. The apparatus of claim 10, wherein said mesh-like, conical-shaped valve comprises one or more fabrics, polymers, pericardial tissue, fascial material, or a biological material coated with an anticoagulant.

12. The apparatus of claim 10, wherein said mesh-like, conical-shaped valve defines one or more openings adapted to permit unidirectional blood flow through said valve.

13. The apparatus of claim 1, comprising two or more elongate support members, a stent, and a valve, wherein said two or more elongate support members are attached to the outer surface of said stent.

14. The apparatus of claim 1, wherein said elongate support member is a hollow tube having a lumen extending between said first end and said second end, wherein said apparatus comprises a micro pump contained within said hollow tube, and wherein said hollow tube comprises a wall that defines one or more lateral openings adjacent to said micro pump such that said lumen is in fluid communication with the external surroundings of said elongate support member in the vicinity of said micro pump.

15. The apparatus of claim 1, wherein said two or more intracardiac devices comprise two or more piezoelectric elements.

16. The apparatus of claim 15, wherein each of said two or more piezoelectric elements comprise a radial array.

17. The apparatus of claim 15, wherein said two or more piezoelectric elements comprise at least one radial array and at least one linear array.

18. The apparatus of claim 15, wherein at least one of said piezoelectric elements is a radial array adapted for placement in the left atrium, at least one of said piezoelectric elements is a radial array adapted for placement at about the site of the mitral valve, and at least one of said piezoelectric elements is a radial array adapted for placement in the left ventricle.

19. The apparatus of claim 15, wherein at least one of said piezoelectric elements is a radial array adapted for placement in the right atrium, at least one of said piezoelectric elements is a radial array adapted for placement at about the site of the tricuspid valve, at least one of said piezoelectric elements is a radial array adapted for placement in the right ventricle, and at least one of said piezoelectric elements is a linear array adapted for placement in the right ventricle.

20. The apparatus of claim 1, wherein said anchor means is a screw, a hook, or a barb.

21. The apparatus of claim 1, wherein said apparatus is adapted for placement in the coronary sinus.
