AORTIC INSUFFICIENCY REPAIR DEVICE AND METHOD
First Claim
1. A method comprising:
- introducing a guidewire into a patient'"'"'s body;
advancing the guidewire until a distal end portion of the guidewire extends into the aortic root and into one of the coronary arteries;
advancing a prosthetic device along the guidewire into the aortic root;
aligning a side opening of the prosthetic device with the coronary artery into which the guidewire extends; and
radially expanding the prosthetic device within the aortic root.

Abstract
The present application concerns embodiments of methods, systems, and apparatus for treating aortic insufficiency. Disclosed methods, systems and apparatus can also be used to treat aortic root dilation. Certain embodiments include a percutaneous or minimally invasively implantable prosthetic device, such as a stented graft, that is configured to be implanted in the sinus of Valsalva (the aortic sinuses) and anchored within one or both of the coronary arteries. An expandable prosthetic heart valve can then be implanted in the previously implanted prosthetic device. In patients suffering from root dilation, another percutaneous or minimally invasively implantable graft can be implanted within the ascending aorta.

14. An implantable prosthetic device configured for implantation in the aortic root of a patient, the prosthetic device comprising:
-
an annular body configured to be radially compressed to a delivery state for insertion into the patient and expandable to an expanded state against the inner wall of the aortic root; and first and second openings in the annular body and configured to allow blood to flow outwardly through the openings and into the coronary arteries when the annular body is in an expanded state engaging the inner wall of the aortic root. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A medical device assembly comprising:
-
first and second guidewires; an elongated delivery apparatus having a distal end portion; and an implantable prosthetic device configured to be implanted within the aortic root of a patient'"'"'s body, the prosthetic device being mounted in a radially compressed state on the distal end portion of the delivery apparatus, the prosthetic device comprising an annular body and first and second openings in the annular body and configured to allow blood to flow outwardly through the openings and into the coronary arteries when the annular body is in an expanded state engaging the inner wall of the aortic root; wherein the first and second guidewires extend into and through the first and second openings, respectively, and through the annular body.
