ABSTRACT:
This method and device permits removal of venous blood from either atrium to a heart lung machine and thereafter returns it (after oxygenation and filtration if needed) to the femoral artery, all in a percutaneous mode. The device includes in combination a guide wire, catheter, transseptal needle, blunt internal obturator approximately the same length as the catheter with a circular barb to secure the catheter in a given longitudinal relationship, an external obturator about the same length as the internal obturator and removably attached thereto, a cannula for passage over the combined obturators and catheter and connectors to attach the cannula to an extracorporeal pump (and oxygenator if needed), which in turn can be connected to the arterial side of a patient's vascular system.
