Abstract
A device for delivering oxygenated blood and occluding the ascending aorta is provided. The device has a blood flow lumen with a movable portion.

The movable portion is made of a tube of flexible material and everts when moving to the extended position.
Claims25
A method of occluding a patient's ascending aorta and delivering oxygenated blood to the patient, comprising the steps of:
- providing a device having a body, an expandable member and a blood flow lumen, the expandable member being movable from a collapsed shape to an expanded shape, the blood flow lumen having a movable portion which is movable relative to the body, the movable portion having an outlet;
- introducing the device into the patient's aorta to position the expandable member in the ascending aorta;
- moving the movable portion so that the movable portion moves to a position within the body to a position which extends outwardly from the body;
- expanding the expandable member to occlude the ascending aorta;
- and
- delivering oxygenated blood to the patient through the blood flow lumen and out of the outlet of the movable portion.
A device for occluding a patient's ascending aorta and delivering oxygenated blood to the patient, comprising:
- a body;
- an expandable member coupled to the body, the expandable member being movable from a collapsed shape to an expanded shape;
- a blood flow lumen coupled to the body, the blood flow lumen configured to deliver blood and having a movable portion which is movable relative to the body, the movable portion being movable from a position contained within the body to an extended position in which the movable portion extends outwardly from the body.
A device for occluding a patient's ascending aorta and delivering oxygenated blood to the patient, comprising:
- a body having a blood flow lumen configured to deliver blood into the sortie arch;
- an expandable member coupled to the body, the expandable member being movable from a collapsed shape to an expanded shape;
- and
- a movable portion substantially disposed within the blood flow lumen, the movable portion configured to be movable between a first position where it is substantially disposed within the blood flow lumen and a second position where the movable portion extends outwardly from the body.
