Abstract

A device and method for improving flow through a native blood vessel valve, such as the aortic valve, are provided. The present invention allows a miniature valve to be implanted into affected leaflets percutaneously, obviating the need for coronary bypass surgery. The method includes the cutting of small holes, on the order of 4 mm, in the leaflets of a targeted valve, thereby allowing blood to flow through the newly formed holes. The holes are used as attachment sites for the miniature valves of the present invention.

Claims (14)

1. A method of increasing fluid flow through a blood vessel valve comprising creating an opening through, and within the confines of, a leaflet of the valve through which fluid may flow; placing a valve implant in operational proximity to the opening, the valve implant having a mechanism capable of allowing flow through the implant in a desired direction and blocking flow through the implant in an opposite direction.

2. The method of claim 1 wherein placing a valve implant in operational proximity to the opening comprises percutaneously placing a valve implant in operational proximity to the opening.

3. The method of claim 2 wherein the creating of an opening and the percutaneously placing of a valve implant in operational proximity to the opening are simultaneously performed by urging the valve implant through the leaflet of the valve.

4. A method of increasing fluid flow through a blood vessel valve comprising creating an opening through at least one leaflet of the valve through which fluid may flow wherein placing a valve implant in operational proximity to the opening comprises percutaneously placing a valve implant in operational proximity to the opening and wherein the creating of an opening and the percutaneously placing a valve implant in operational proximity to the opening are simultaneously performed by screwing the valve implant into at least one leaflet of the valve.

5. The method of claim 2 wherein percutaneously placing a valve implant in operational proximity to the opening comprises cutting a hole through the leaflet of the valve and then placing the valve implant into the hole and attaching the valve implant to the leaflet.

6. The method of claim 5 further comprising expanding the hole after attaching the valve implant to the leaflet.

7. The method of claim 6 wherein expanding the valve implant comprises inflating a balloon inside the valve implant until the hole expands to a predetermined diameter.

8. The method of claim 2 wherein percutaneously placing a valve implant in operational proximity to the opening comprises cutting a hole through the leaflet of the valve and then placing the valve implant over the hole and attaching the valve implant to the leaflet.

9. A method of treating a diseased valve comprising:

diagnosing a diseased state of a valve in a patient;

delivering a first prosthetic valve to said diseased valve;

deploying said first prosthetic valve in native tissue of said diseased valve; and

securing said first prosthetic valve in said tissue

placing a second prosthetic valve in said native tissue adjacent said first prosthetic valve following the securing of said first prosthetic valve in said tissue.
