1. A method for connecting cannulae to a cardiac circulatory support device, the method comprising:
- connecting an inflow disposable purging (“
DIP”
) device and an outflow DIP device to an inflow port and an output port, respectively, of a cardiac circulatory support device to form a support device/DIP device assembly;
purging the support device/DIP device assembly of trapped air;
occluding the inflow DIP device and the outflow DIP device;
inserting an outflow cannula into the inflow DIP device and an inflow cannula into the outflow DIP device;
purging air bubbles from each of the inflow DIP device and the outflow DIP device; and
connecting the cannulae to the cardiac circulatory support device to form a support device/DIP device/cannulae assembly.

Abstract
A method for connecting medical tubing or any other type of fluidic circuit conduits (e.g., cannulae) to a ventricular assist device (“VAD”) or any other pumping device used for blood pumping during cardiac circulatory support for vascular surgery. The method prevent air bubbles from entering a cardiac circulatory support system when connecting cannulae to a VAD that may later enter the blood stream of a patient during cardiac surgery, and also provide for purging any air bubbles that may have entered the cardiac circulatory support system during a cannulae-VAD connection.
