Patent number: 10449274Abstract: A system for facilitating fluid connection between cannulae and a blood pump. The system includes a cannula having proximal and distal ends. The distal end of the cannula adapted to be in fluid communication with the circulatory system. The proximal end of the cannula configured to couple to an inlet of the blood pump. The system further includes 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 for connection thereto. The cannula further includes a first connecting structure. The tunneling device further includes a second connecting structure. The first and second connecting structures are selectively engageable to allow connection and disconnection between the cannula and tunneling device.Type: GrantFiled: June 24, 2014Date of Patent: October 22, 2019Assignee: CircuLite, Inc.Inventors: Bryan P.
