  • Patent number: 7905823
    Abstract: A blood circulation assist system comprising an inflow cannula having a lumen and an insertion device configured to be received therein and to facilitate insertion of a portion of the inflow cannula into a heart chamber. The insertion device includes a shaft having distal and proximal end portions and a plurality of lumens. A first lumen is configured to receive a guidewire and a second lumen is configured to receive a pressurized fluid. A tip connected to the distal end portion of the shaft is configured for insertion into the heart chamber. The tip has a hollow interior communicating with the first shaft lumen. An inflatable member is coupled to the distal end portion of the shaft and includes a hollow interior in fluid communication with the second shaft lumen. The inflatable member is movable between deflated and inflated configurations for releasably securing the insertion device to the inflow cannula.

  • Publication number: 20100249491
    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.

  • Publication number: 20100249490
    Abstract: A transseptal cannula having a flexible cannula body, a left atrial anchor coupled to the distal end of the flexible cannula body, and a right atrial anchor operable to be attached to the left atrial anchor in vivo. The left and right atrial anchors are implanted and deployed separately. Delivery of the transseptal cannula to a heart tissue can include a low profile coaxial balloon catheter comprising a tube body including an inner member and an outer member surrounding the inner member and thereby creating an inflation channel between the inner and outer members, a hub coupled to the proximal portion of the tube body and including a fluid space in fluid communication with the inflation channel; and a balloon coupled to the distal portion of the tube body, wherein the balloon is in fluid communication with the inflation channel.

  • Publication number: 20090182188
    Abstract: Devices, systems and methods for establishing a blood flow conduit between a chamber in a heart of a patient and a remote location. A blood inflow cannula having an outer surface and proximal and distal end portions. The distal end portion is configured for insertion into the chamber of the heart. First and second anchor elements have respective maximum width dimensions extending outwardly from the outer surface of the cannula. The first anchor element is positioned more distally than the second anchor element defining a tissue receiving space therebetween. The maximum width dimension of the first anchor element may be larger than the maximum width dimension of the second anchor element in use. The first anchor element is configured to be positioned inside the heart chamber and the second anchor element is configured to be positioned outside the heart chamber with heart tissue held in the tissue receiving space therebetween.

  • Publication number: 20090171137
    Abstract: An intravascular system for pumping blood from a chamber of a heart and through an associated blood vessel coupled in fluid communication therewith. The system includes a pump device configured to be inserted into a blood vessel. The system further includes a catheter having a proximal end coupled to the pump device and a distal end configured to collect blood within or exiting from the chamber. The catheter further includes a pre-formed shape corresponding to the vessel to at least assist with stabilization and positioning of the pump device in the vessel.

    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.

  • Publication number: 20090023975
    Abstract: A cannula for implantation into a chamber of a heart includes an elongate body having a lumen extending along a longitudinal axis, a first end, and a second end. The first and second ends define openings into the lumen and the second end includes a flat portion. A flared tip portion extends from the flat portion of the second end in a direction toward the first end, and flares radially outward from the longitudinal axis and in such direction. A ring member extends around the axis of the elongate body and is spaced from the flared tip portion, and the ring member is adapted for retaining the elongate body in a position relative to a wall of the chamber. An embodiment of a flared tip portion may further include a barbed surface configured to contact tissue around an aperture in the wall of the heart when the cannula travels through the aperture.

  • Publication number: 20080076960
    Abstract: An insertion device for inserting a cannula through tissue generally comprises an inner shaft, a tip member coupled to a distal end portion of the inner shaft, a hollow outer shaft slidably received over the inner shaft, and a compressible member received over the inner shaft between the tip member and the outer shaft. The compressible member is configured to be received in a lumen of the cannula, and the inner shaft is movable relative to the outer shaft along an axial direction to compress the compressible member between the tip member and the outer shaft so that the compressible member expands in a generally radially outward direction. The radial expansion of the compressible member releasably secures the insertion device to the cannula.
