Abstract

The present invention is an apparatus designed to effectuate restoration of normal aortic valvular function where there is aortic valvular regurgitation, either primary or secondary to diseases of the aorta, such as aortic aneurysm, aortic dissection, rheumatic aortic disease, annuloaortic ectasia, etc. are present. The present invention also provides methods of using the apparatus to treat conditions of abnormal aortic valvular function.

Claims

1. A treatment method for aortic valvular regurgitation associated with an aortic valve having an aortic annulus, an aortic lumen and a sinotubular junction, comprising:

implanting an inner discontinuous band stabilizer inside the aortic lumen along an interior surface of the aortic annulus of the aortic valve,

implanting an outer discontinuous band stabilizer outside the aortic lumen along an exterior surface of the aortic annulus of the aortic valve;

implanting an inner continuous ring stabilizer along an interior surface of the sinotubular junction of the aortic valve; and

implanting an outer continuous ring stabilizer along an exterior surface of the sinotubular junction of the aortic valve.

2. A treatment method for aortic valvular regurgitation associated with an aortic valve having an aortic annulus, an aortic lumen and a sinotubular junction, comprising:

implanting an inner discontinuous band stabilizer inside the aortic lumen proximate the aortic annulus of the aortic valve, wherein the inner discontinuous band stabilizer comprises a sewing passage wherein a portion of the inner discontinuous band stabilizer is thinner than surrounding portions of the inner discontinuous band stabilizer;

implanting an outer discontinuous band stabilizer outside the aortic lumen proximate the aortic annulus of the aortic valve;

implanting an inner continuous ring stabilizer proximate an interior surface of the sinotubular junction of the aortic valve, wherein the inner continuous ring stabilizer comprises a sewing passage wherein a portion of the inner continuous ring stabilizer is thinner than surrounding portions of the inner continuous ring stabilizer; and

implanting an outer continuous ring stabilizer proximate an exterior surface of the sinotubular junction of the aortic valve.

3. The treatment method for aortic valvular regurgitation as set forth in claim 2, wherein the outer continuous ring stabilizer comprises three equally spaced markers on its circumference.

4. The treatment method for aortic valvular regurgitation as set forth in claim 2, wherein the outer discontinuous band stabilizer comprises vertical marks about 2 mm from each free end thereof.

5. The treatment method for aortic valvular regurgitation as set forth in claim 2, wherein no graft or prosthetic flexible tubular structure is used between the outer discontinuous band stabilizer and the outer continuous ring stabilizer.

6. The method of claim 2 wherein the outer continuous ring stabilizer, the inner continuous ring stabilizer, the outer discontinuous band stabilizer, and the inner discontinuous band stabilizer each comprise a synthetic fiber.

7. A treatment method for aortic valvular regurgitation associated with an aortic valve having an aortic annulus, an aortic lumen and a sinotubular junction, comprising:

implanting an inner discontinuous band stabilizer inside the aortic lumen proximate the aortic annulus of the aortic valve;

implanting an outer discontinuous band stabilizer outside the aortic lumen proximate the aortic annulus of the aortic valve;

implanting an inner continuous ring stabilizer proximate an interior surface of the sinotubular junction of the aortic valve; and

implanting an outer continuous ring stabilizer proximate an exterior surface of the sinotubular junction of the aortic valve, wherein the outer continuous ring stabilizer, the inner continuous ring stabilizer, the outer discontinuous band stabilizer, and the inner discontinuous band stabilizer each comprise a synthetic fiber.

8. A treatment method for aortic valvular regurgitation associated with an aortic valve having an aortic annulus, an aortic lumen and a sinotubular junction, comprising:

implanting an inner discontinuous band stabilizer inside the aortic lumen proximate the aortic annulus of the aortic valve, wherein the inner discontinuous band stabilizer comprises vertical marks about 2 mm from each free end thereof;

implanting an outer discontinuous band stabilizer outside the aortic lumen proximate the aortic annulus of the aortic valve, wherein the outer discontinuous band stabilizer comprises vertical marks about 2 mm from each free end thereof;

implanting an inner continuous ring stabilizer proximate an interior surface of the sinotubular junction of the aortic valve; and

implanting an outer continuous ring stabilizer proximate an exterior surface of the sinotubular junction of the aortic valve.
