  • Patent number: 10729831
    Abstract: A system for facilitating fluid connection between cannulae and a blood pump. The system includes a cannula having a distal end adapted to be in fluid communication with the circulatory system and a proximal end configured to couple to an inlet of the blood pump. Further included is 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 and including a second connecting structure. Further included is a plug which has a first plug part and a second plug part. The first plug part includes a second connecting structure, the first and second connecting structures being selectively engageable. The second plug part is configured to be inserted in the proximal end of the cannula. The first and second plug parts are selectively disengageable to allow in situ disconnection between the cannula and tunneling device.

  • Publication number: 20190374694
    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.
