Blood vessel occlusion device
First Claim
1. A method of cannulating a patient ascending aorta in preparation for surgery, comprising the steps of;
- providing an aortic occlusion device having a cutting element, a first lumen, a second lumen and an occluding member, the occluding member being movable from a collapsed condition to an expanded condition;
incising the patient'"'"'s ascending aorta with the cutting element and inserting the aortic occlusion device into the patient'"'"'s ascending aorta;
coupling the first lumen to a source of oxygenated blood;
expanding the occluding member to the expanded condition thereby occluding the patient'"'"'s ascending aorta;
coupling the second lumen to a source of myocardial protection solution;
delivering myocardial protection solution into the patient'"'"'s ascending aorta through the second lumen; and
infusing oxygenated blood into the patient from the source of oxygenated blood.

Abstract
An occluder apparatus for obstructing the flow of blood in a blood vessel has an elongated hollow tubular body having a leading end sized for reception in the blood vessel and includes portion of the body fabricated from a material soluble in blood, and a piercing device for inserting the body through the wall of the blood vessel to extend the leading end into the interior of the blood vessel. An inflatable diaphragm is carried by the body in a collapsed, deflated condition, and the apparatus includes a passage for conducting an inflating fluid from an external source, which is into fluid communication with the interior of the diaphragm, to effect expansion the diaphragm. Elongated openings in the body enable the diaphragm to be released in an inflated state from the body into flexible occluding engagement with the interior wall of the blood vessel about the full circumference of a transverse section thereof.

5. A method of cannulating a patient'"'"'s ascending aorta in preparation for surgery, comprising the steps of:
-
providing an aortic occlusion device having a tubular body, a stop, a distal end, a first lumen, a second lumen and an occluding member, the occluding member being movable from a collapsed condition to an expanded condition, the stop extending outwardly from the tubular body; inserting the aortic occlusion device through a penetration in the patient'"'"'s ascending aorta until the stop contacts the patient'"'"'s ascending aorta, the tubular body extending from the penetration toward an opposite wall of the patient'"'"'s ascending aorta; coupling the first lumen to a source of oxygenated blood; expanding the occluding member to the expanded condition thereby occluding the patient'"'"'s ascending aorta; coupling the second lumen to a source of myocardial protection solution; delivering myocardial protection solution into the patient'"'"'s ascending aorta through the second lumen; and infusing oxygenated blood into the patient from the source of oxygenated blood. - View Dependent Claims (6, 7, 8, 9, 10)
