Abstract
A cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The cannula assembly includes a flexible cannula body having a proximal end and a distal end with a receiving portion, and a transseptal tip having a distal end and a proximal end with an engaging portion. First and second anchors are coupled to the transseptal tip and configured to be deployed from a contracted state to an expanded state. The engaging portion of the transseptal tip is operable to removably engage the receiving portion of the flexible cannula body in vivo.
