Abstract
An endovascular perfusion stent graft is provided that can include a graft device, a balloon, and a perfusion port. The graft device can be configured to be inserted into a vessel. The balloon can be configured to temporarily restrict passage of air or fluid through the vessel when the balloon is temporary inserted into the graft device. The perfusion port can be configured to selectively allow passage of the fluid or the gas through the balloon and to the vessel. The perfusion port can be connected to another perfusion port or to a collection device, such as a heart lung machine. The vessel can be one of an ascending aorta, a descending aorta, or an arch of an aorta.
Claims20
A system, comprising:
- a graft device configured to be inserted into a vessel;
- a balloon configured to temporarily restrict passage of fluid or gas through the vessel when the balloon is temporary inserted into the graft device;
- and
- a perfusion port configured to selectively allow the passage of the fluid or the gas through the balloon and to the vessel.
A method, comprising:
- inserting a graft device into a vessel;
- deploying an expandable device into the graft device;
- causing the expandable device to push the graft device outward;
- and
- pushing the graft device into contact with an inner wall of the vessel.
A graft device comprising:
- a graft configured to provide a conduit for blood flow;
- a stent configured to provide structure support to the graft and push the graft toward a vessel;
- and
- at least one fastener configured to securely anchor the graft to the vessel as the graft contacts the vessel.
