Abstract

This is an intravascular prothesis deliverable percutaneously with several cardiac applications including but not limited to heart valves, intravascular narrowings and cardiac defect occlusion. The device has a detachable sac connected through a thread or wire outside the body where it is immobilized. The device can remain inside the heart for as long as it is clinically useful in non permanent applications (valve, throttle); at any point it can be retrieved by pulling it outside the body by the holding wire/thread. In permanent applications (defect occlusion) the wire/thread can be withdrawn allowing the sac to endothelialize.

Claims

1. The method of repairing a defect in a vascular system component of a patient comprising the steps of:

introducing a sac through the skin of said patient, said sac having a sealable mouth and a volume for filling with a liquid;

placing the sac adjacent to said defect in the component;

filling the sac with a liquid, said liquid including a radiopaque component;

sealing the mouth of the sac; and

tying the sac at its mouth with a holding wire, said holding wire having a first and second end, said first end being tied to the sac.

2. The method as defined in claim 1 wherein said defect is a faulty heart valve and the sac functions as an artificial valve member positioned so that the sac operates in conjunction with an existing valve annulus.

3. The method as defined in claim 1 wherein said defect is an opening, and said opening is occluded by the sac.

4. The method as defined in claim 3 further comprising retrieving the sac.

5. The method as defined in claim 3 further comprising at least temporarily tethering the sac by immobilizing said second end of said holding wire on the skin of said patient.

6. The method as defined in claim 5 further comprising holding the sac in position by using a counter occluder, and retrieving the sac if desired.

7. The method as defined in claim 5 further comprising holding the sac in position by using a sutured floppy disk, and retrieving the sac if desired.

8. The method as defined in claim 3 further comprising fixing the sac in position by attaching a counter occluder to the sac.

9. The method as defined in claim 3 further comprising fixing the sac in position by attaching a sutured floppy disk to the sac.

10. The method as defined in claim 3 wherein said opening is a septal defect, and further comprising using the sac for occluding the septal defect where there is an insufficient septal rim for other known occlusion methods.

11. The method as defined in claim 1 wherein said defect is excessive flow in an artery of the patient, and the sac is used to restrict the excessive flow in the artery.

12. The method as defined in claim 11 further comprising retrieving the sac.

13. The method as defined in claim 11 further comprising tethering the sac by immobilizing said second end of said holding wire on the skin of said patient.

14. The method as defined in claim 11 further comprising centering the sac in the artery by using a stabilizing wire attached to the mouth of the sac.

15. The method as defined in claim 11 further comprising at least temporarily tethering the sac by immobilizing said second end of said holding wire on the skin of said patient, holding the sac centered in the artery by a stabilizing wire, and retrieving the sac.

16. A device for occluding vascular system defects in a patient comprising:

a sac occluder having a sealable mouth and a volume filled with a liquid; and

a holding wire, said holding wire having a first and second end, said first end being tied to the mouth of the sac;

whereby the sac occluder is capable of being held in position within the vascular system, at least temporarily, by immobilizing said second end of said wire on the skin of said patient.

17. The device of claim 16 wherein the sac occluder is flexible and conforms to a shape of the defect being occluded.

18. The device of claim 16 further comprising a counter occluder, and whereby the sac occluder may be fixed in position within the vascular system by attaching the sac occluder to said counter occluder.

19. The device of claim 16 further comprising a sutured floppy disk, and whereby the sac occluder may be fixed in position within the vascular system by attaching the sac occluder to said floppy disk.

20. The device of claim 16 whereby the sac occluder functions in operational relationship to an existing valve annulus within the vascular system to seat against said annulus during a normal operational cycle.

21. The device of claim 20 wherein the valve annulus is a heart valve annulus.

22. The device of claim 16 wherein the liquid filling the sac occluder has a radiopaque component.
