TWO-PIECE TRANSSEPTAL CANNULA, DELIVERY SYSTEM, AND METHOD OF DELIVERY

摘要

PROBLEM TO BE SOLVED: To provide a cannula assembly for directing blood from the heart of a patient, and a minimally invasive method of implanting the assembly.SOLUTION: A cannula assembly includes a flexible cannula body (310) having a proximal end and a distal end having a receiving portion, and a transseptal tip (186) having a distal end and a proximal end having an engaging portion. First and second anchors (202, 206) are coupled to the transseptal tip (186) and configured to be deployed from a contracted state to an expanded state. The engaging portion (198) of the transseptal tip (186) is operable to removably engage the receiving portion of the flexible cannula body (310) in vivo.
