Abstract
A system for drawing blood from a heart of a patient, includes a blood pump, an outflow cannula and a flexible cannula assembly. The cannula assembly further includes a flexible cannula body including a proximal end, a distal end, an inner wall defining a lumen, and an outer wall. A tip is coupled with the distal end of the cannula body, and an anchor is coupled to the tip. The anchor is configured to engage an internal structure of the heart and resists movement of the cannula assembly in at least one direction along the flexible cannula body. A ring member is configured to be coupled to the heart wall and is positioned at least partially around the outer wall of the cannula body proximally relative to the tip. The ring member is further configured to provide hemostasis between the heart wall and the cannula body.
