Abstract
A system 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 system prevents 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.
Claims3
A system for connecting cannulae to a cardiac circulatory support device for use in a cardiac circulatory support system, the system comprising:
- two disposable purging (“DIP”) devices each having a distal ending and a proximal ending;
- a cardiac circulatory support device for use in a cardiac circulatory support system having inflow and outflow ports;
- connectors configured to attach the distal ending of a connector to each of the inflow and outflow ports;
- and
- cannulae configured for attachment to each of the inflow and outflow ports,
- wherein the proximal ending of each of the two DIP devices is configured to connect to one of the connectors, and
- the distal ending of each of the two DIP devices is configured for insertion of a cannula within the DIP device such that the cannulae can be inserted into the DIP devices at the distal endings and attached to the inflow and outflow ports of the cardiac support device.
