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

2-1. The system of claim 1, further comprising:

an arterial circulatory support occluding member lumen coupled to the arterial circulatory support occluding member and positioned in the arterial circulation support catheter.

3-2. The system of claim 1 and 2, wherein the arterial circulatory support occluding member is slideably positioned in the blood lumen or the arterial circulation support occluding member lumen.

39. An extracorporeal support system coupled to a blood circulation, comprising:

an extracorporeal support apparatus;

an arterial circulation support catheter including a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end inserted into the blood circulation;

an arterial circulation support catheter occluding member positioned in an interior or at an exterior of the arterial circulation support catheter;

a vent lumen with a distal end positioned in the left ventricle and provide direct venting of the left ventricle, wherein the vent lumen is positioned in the interior or the exterior of the arterial circulatory support lumen.

a venous circulation support catheter including a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end inserted into the blood circulation; and

a venous circulation support catheter occluding member to occlude the superior vena cava and the inferior vena cava, the venous circulation support catheter occluding member being positioned in an interior or at an exterior of the venous circulation support catheter.

42. A method for venting a left ventricle of a heart, comprising:

providing an extracorporeal circulation support system including an extracorporeal support apparatus, a venous circulation support catheter, an arterial circulation support catheter and a vent lumen;

introducing the arterial circulation support catheter into a blood circulation;

introducing the venous circulation support catheter into the blood circulation;

positioning a vent lumen distal end into a left ventricle of the heart; and

venting the left ventricle rough the vent lumen.

43. The method of claim 42, wherein a proximal end of the arterial circulation support catheter is coupled to an outlet port of the extracorporeal support device.

44. The method of claim 43, wherein a proximal end of the venous circulation support catheter is coupled to an inlet port of the extracorporeal support device.

45. The method of claim 42, wherein the left ventricle is directly vented through the vent lumen.
