Abstract
Abstract An extracorporeal support system including an extracorporeal support apparatus and an arterial circulation support catheter. The arterial circulation support catheter includes a blood lumen with a proximal end coupled to extracorporeal support apparatus and a distal end inserted into the blood circulation. A vent lumen has a distal end that crosses the aortic valve into the left ventricle and provides direct venting of the left ventricle through the vent lumen. An arterial circulation support catheter occluding member is positioned either in an interior or at an exterior of the arterial circulation support catheter. A venous circulation support catheter is provided and includes a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end inserted into the blood circulation. A venous circulation support catheter occluding member is included and positioned in an interior or at an exterior of the venous circulation support catheter. The venous circulation support catheter occluding member occludes the superior vena cava and the inferior vena cava.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
A method of delivering cardioplegic fluid to a patient's coronary arteries comprising the steps of: providing a catheter having a lumen, a distal end, and an occluding member, the occluding member being movable between a collapsed condition and an expanded condition, the lumen having an outlet positioned distal to the occluding member; inserting the distal end of the catheter through an opening in a patient's artery; passing the distal end of the catheter through the patient's subclavian artery and into the ascending aorta so that the occluding member is positioned in the ascending aorta; infusing a cardioplegic fluid through the lumen of the catheter and into the patient's aortic root thereby perfusing the patient's coronary arteries to arrest the patient's heart; passing a blood flow lumen through the opening in the artery; coupling the blood flow lumen to a source of oxygenated blood; infusing oxygenated blood through the blood flow lumen from the source of oxygenated blood; and moving the occluding member to the expanded condition to occlude the patient's ascending aorta.
Claim 2
Independent Claim
172 words
A method of delivering cardioplegic fluid to a patient's coronary arteries comprising the steps of: providing a catheter having a lumen, a distal end, and an occluding member, the occluding member being movable between a collapsed condition and an expanded condition, the lumen having an outlet positioned distal to the occluding member; inserting the distal end of the catheter through an opening in a patient's artery; passing the distal end of the catheter through the patient's subclavian artery and into the ascending aorta so that the occluding member is positioned in the ascending aorta; infusing a cardioplegic fluid through the lumen of the catheter and into the patient's aortic root thereby perfusing the patient's coronary arteries to arrest the patient's heart; passing a blood flow lumen through the opening in the artery; coupling the blood flow lumen to a source of oxygenated blood; infusing oxygenated blood through the blood flow lumen from the source of oxygenated blood; and moving the occluding member to the expanded condition to occlude the patient's ascending aorta.
Claim 3
Dependent Claim
48 words
The method of delivering cardioplegic fluid of claim 1, wherein: the passing steps are carried out with the blood flow lumen and catheter being slidable relative to one another, the blood flow lumen having an outlet which is slidably movable relative to the outlet of the catheter lumen.
