Vascular graft device placement methods
First Claim
1. A method for positioning a device in a blood vessel of a patient adjacent to the heart, the method comprisingadvancing a venous catheter endoluminally from a venous site to the heart;
- advancing an elongate member from the venous catheter through a valve in the heart to a blood vessel adjacent to the heart;
advancing an arterial catheter endoluminally from an arterial site toward the heart;
drawing the elongate member into the arterial catheter;
advancing the arterial catheter over the elongate member such that tip portions of the venous and arterial catheters are brought into adjacency; and
deploying a device within the blood vessel from a platform extending from the venous catheter to the arterial site, the blood vessel being adjacent to the heart.

Abstract
In another embodiment, a method is provided for positioning a graft device in an ascending aorta of a patient. In the method, access is provided to a peripheral venous site. A first catheter is advanced through the peripheral venous site to a right atrium of the patient. Access is provided to the left atrium across an intra-atrial septum. The first catheter is advanced through to a left atrium of a patient. A second catheter is advanced from the first catheter through a left ventricle and the aorta to a peripheral arterial site. A graft device disposed on, over or within the second catheter is advanced from the peripheral venous site or the peripheral arterial site until the graft device reaches an ascending aorta of the patient. The graft device is positioned at a treatment site within the ascending aorta. The first and second catheters are removed from the patient.

18. A method for positioning a device in a blood vessel of a patient adjacent to the heart, the method comprising:
-
advancing a venous catheter endoluminally from a venous site to the heart;
advancing a snare from the venous catheter through a valve in the heart to a blood vessel adjacent to the heart;advancing a shaped wire endoluminally from an arterial site toward the heart; drawing the shaped wire into the venous catheter using the snare to provide a rail from the arterial site to the venous site; advancing an arterial catheter over the shaped wire such that tip portions of the venous and arterial catheters are brought into adjacency; and deploying a device within the blood vessel from a platform extending from the venous catheter to the arterial site, the blood vessel being adjacent to the heart. - View Dependent Claims (19, 20, 21, 22, 23)
