Abstract
A system for facilitating fluid connection between cannulae and a blood pump. The system includes a cannula having a distal end adapted to be in fluid communication with the circulatory system and a proximal end configured to couple to an inlet of the blood pump. Further included is a tunneling device configured to be inserted into a body of a patient to direct the proximal end of the cannula adjacent to the inlet and including a second connecting structure. Further included is a plug which has a first plug part and a second plug part. The first plug part includes a second connecting structure, the first and second connecting structures being selectively engageable. The second plug part is configured to be inserted in the proximal end of the cannula. The first and second plug parts are selectively disengageable to allow in situ disconnection between the cannula and tunneling device.
