Abstract:
1. A transseptal blood flow cannula assembly comprising: a flexible cannula body having distal and proximal ends with a lumen extending therebetween, the lumen configured to receive blood flow and direct the blood flow between the distal and proximal ends; a left atrial anchor coupled to the distal end of the flexible cannula body, the left atrial anchor configured to be deployed from a contracted state to an expanded state to engage at least one side of heart tissue in the expanded state; a right atrial anchor attachable to the left atrial anchor in vivo, the right atrial anchor configured to be deployed from a contracted state to an expanded state to engage an opposing side of the heart tissue in the expanded state; whereby, with the left and right atrial anchors deployed and engaged respectively to opposite sides of the heart tissue, blood flow may be directed between the distal and proximal ends; a right anchor delivery apparatus configured to engage the left atrial anchor and couple the right atrial anchor to the left atrial anchor; and a right anchor sheath having a proximal hub and a sheath body configured to receive the right anchor delivery apparatus and move relative thereto for deploying the right atrial anchor into the expanded state.
