System and method of facilitating connection between cannulae and a blood pump
First Claim
1. A system for facilitating fluid connection between a blood pump and a circulatory system of a patient, comprising:
- 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; and
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;
wherein the cannula further comprises a first connecting structure; and
the tunneling device further comprises a second connecting structure, the first and second connecting structures being selectively engageable to allow in situ connection and disconnection between the cannula and tunneling device.

Abstract
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.

28. A method of facilitating fluid connection between a blood pump and a circulatory system of a patient, comprising:
-
directing a distal end of a cannula into fluid communication with the circulatory system; inserting the blood pump into a body of the patient; inserting a tunneling device into the body of the patient; selectively engaging a first connecting structure of the cannula in situ with a second connecting structure of the tunneling device; directing a proximal end of the cannula adjacent to an inlet of the blood pump; and connecting the proximal end of the cannula to the inlet. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
