  • Patent number: 10350384
    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.

  • Patent number: 9211367
    Abstract: 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.

  • Patent number: 8343029
    Abstract: A transseptal cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly includes a flexible cannula body having proximal and distal portions with a lumen therebetween, a tip coupled to the distal portion of the flexible cannula body, and first and second anchors coupled to the tip. The anchors can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue when in the expanded state. The anchors resist movement of the cannula assembly along a lengthwise central axis of the flexible cannula body.
