Abstract
Improved methods of treatment of diseased or occluded vascular grafts in patients having undergone coronary artery bypass or other bypass surgery are disclosed. Deployment of a conduit in the myocardium at a site distal to the site of attachment of the coronary artery bypass graft allows oxygenated blood to flow from a chamber in the heart directly into the coronary artery, bypassing blockages in the coronary artery and the graft originally used to bypass the coronary artery. To ensure proper positioning, the conduit is delivered through the graft to the myocardium. A new lining for the existing vein graft and methods of delivery are also disclosed.
Claims17
A method for placing a conduit in a heart wall between a heart chamber and a coronary vessel, comprising:
- providing a conduit on a distal end of a delivery catheter;
- advancing the delivery catheter and the conduit through a bypass graft;
- inserting the conduit in the heart wall between the heart chamber and the coronary vessel at a location proximate a site of attachment of the bypass graft;
- and
- anchoring the conduit in position within the heart wall.
