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 In permanent applications (defect occlusion) the wire/thread can be withdrawn allowing the sac to endothelialize.
Claims22
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.
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.
