摘要： A cannula assembly, further comprising a cannula body for directing blood from the heart of a patient, having distal and proximal ends and a lumen therebetween. A tip coupled to the distal end of the body, the tip having an opening. A pump for drawing blood into the cannula assembly and dispensing the blood from the cannula assembly and into the patient circulatory system. The lumen of the cannula body further comprises a first inner diameter at the proximal end and a second inner diameter at the distal end, the first inner diameter being larger than the second inner diameter. A tapered portion defined as a decrease in inner diameter from the first inner diameter to the second inner diameter between the proximal and distal ends, the tapered portion configured to prevent cavitation of the blood within the cannula.

摘要： 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.

摘要： 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.
