  • Patent number: 10632239
    Abstract: A centrifugal blood pump uses the “double suction” arrangement of the blood flow channels, by dividing the blood flow across the impeller into two practically identical streams, one flowing across the upstream side of the impeller and the other flowing across the downstream side. The double suction arrangement is obtained by using a “flow through cone bearing” mounted to the hub of the impeller. The impeller is attached to the driving motor by three posts, which do not significantly diminish the flow area. The annular flow through the motor “air gap” reaches the flow channel as a single stream and divides into two streams in the vicinity of the posts. The flow is distributed equally to the two sides of the impeller. After passing across the impeller the two streams combine into one that enters the spiral volute and continues past the pump cutwater and through the outflow channel.

  • Patent number: 10478542
    Abstract: An intravascular heart pump assembly can include a rotor with at least one impeller blade, and a cannula. The present application describes various cannulas that can be manufactured from multiple layers of material to improve flexibility, manufacturability, and durability without increasing an outer diameter of the cannula. In one embodiment, the cannula includes an inflow section having a sheet formed of a shape memory material embedded within a polymer and having at least one lateral hole or aperture in the inflow section. The at least one lateral hole is defined by a first hole in the sheet and a second hole in the outer polymer layer of the cannula. The first hole and the second hole overlap so that blood can enter the cannula through the holes.

  • Patent number: 10463843
    Abstract: A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway to be connected to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway, a filter provided in the blood flow passageway for collecting blood clots occurring in the blood flowing through the blood flow passageway, and a cleaning device for moving blood clots collected by the filter out of the blood flow passageway. By means of such blood clot removal device, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.

  • 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: 10426879
    Abstract: A control circuit includes a pump shutdown module responsive to one or more inputs indicating at least from the group consisting of an operational error at the implantable blood pump and an adverse physiological state of a user of the implantable blood pump. The pump shutdown module ceases operation of the implantable blood pump in response to the one or more inputs. A pump restart module configured to resume operation of the implantable blood pump in response to a first pump restart input and a second pump restart input is included. A pump restart lockout module configured to initiate a pump lockout mode in response to a lockout input is included. The pump lockout mode prevents resumption of operation of the implantable blood pump in response to the first pump restart input and allows resumption of operation of the implantable blood pump in response to the second pump restart input.

  • Patent number: 10405978
    Abstract: A method is provided of reducing tricuspid valve regurgitation of a patient. A first tissue anchor is implanted at a first implantation site in cardiac tissue in the vicinity of the tricuspid valve of the patient. A second tissue anchor is implanted at a second implantation site of the patient, different from the first implantation site. After the first and the second tissue anchors have been implanted, a longitudinal member that couples the first and the second tissue anchors together is longitudinally deflected.

  • Patent number: 10398435
    Abstract: Embodiments of invention are directed to tissue approximation instruments that may be delivered to the body of a patient during minimally invasive or other surgical procedures. In one group of embodiments, the instrument has an elongated configuration with two sets of expandable wings that each have spreadable wings that can be made to expand when located on opposite sides of a distal tissue region and a proximal tissue region and can then be made to move toward one another to bring the two tissue regions into a more proximate position. The instrument is delivered through a needle or catheter and is controlled by relative movement of a push tube and control wire wherein the control wire can be released from the instrument via rotation in a first direction and can cause release of the approximation device from tissue that it is holding by rotation in the opposite direction.
