  • Patent number: 10518011
    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.

  • Patent number: 10449274
    Abstract: A system for facilitating fluid connection between cannulae and a blood pump. The system includes a cannula having proximal and distal ends. The distal end of the cannula adapted to be in fluid communication with the circulatory system. The proximal end of the cannula configured to couple to an inlet of the blood pump. The system further includes a tunneling device configured to be inserted into a body of a patient to direct the proximal end of the cannula adjacent to the inlet for connection thereto. The cannula further includes a first connecting structure. The tunneling device further includes a second connecting structure. The first and second connecting structures are selectively engageable to allow connection and disconnection between the cannula and tunneling device.

  • Patent number: 10342913
    Abstract: A cannula for moving fluids between a pump and the circulatory system of a patient. The cannula includes a liner having an intermediate portion between a proximal portion and a distal portion, and a lumen extending between the proximal and distal portions. At least the intermediate portion of the liner is constructed from a tissue in-growth material for supporting the growth of endothelial cells. A jacket surrounds at least part of the liner.

  • Patent number: 10342905
    Abstract: A fluid flow system for a patient is disclosed. A fluid drive module includes a fluid drive element, a housing, and a chamber located between the housing and the fluid drive element. A controller or control module modifies the speed of the fluid drive element during use, such as to prevent thrombus or otherwise improve flow conditions. Methods of alternating fluid flow are also provided.

  • Publication number: 20180147334
    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: 20180147339
    Abstract: The invention relates to an arrangement having a blood pump and a gas exchanger for extracorporeal membrane oxygenation. According to the invention, the blood pump is designed as a pulsatile blood pump and is arranged with the gas exchanger in the same housing. The pulsatile blood pump and the gas exchanger are preferably connected to the same gas source so that the blood pump can be pneumatically driven. The novel ECMO system has a simple design, is flexible, and in particular can be used directly on the patient.

  • Publication number: 20180087500
    Abstract: A test controller and method to operate a rotary motor of a pump are provided. The test controller includes a test speed circuit electrically coupled to, but detachable from, the pump and being configured to apply at least one signal to the pump motor to cause the pump motor to rotate at a predetermined test speed and/or for a predetermined test time. An actuator selectively activates the test speed circuit to operate the pump motor at the predetermined test speed and/or for the predetermined test time. The method includes electrically coupling the test controller to the pump and, in response to selective activation of the actuator, selectively activating the test speed circuit to apply at least one signal to the pump motor to operate the pump motor at a predetermined test speed and/or for a predetermined test time. The method further includes detaching the test controller from the pump.
