  • Patent number: 11974748
    Abstract: A system and method for end-to-side anastomosis to an anatomical passageway is disclosed. The system and method are particularly useful in coupling an LVAD pump to an aorta. The system and method include using a tubular graft member having a skirt flange that engages the side of the aorta, a seating assembly and a flanged stent for securing the tubular graft to the side of the anatomical passageway. An assembly for creating an opening in the side of the anatomical passageway and an assembly for delivering the tubular graft is also disclosed.

  • Publication number: 20240082568
    Abstract: An apical cuff axial compression assembly including a ring member for coupling an apical cuff of a Ventricular Assist Device pump, to left ventricular apical tissue. Tissue anchors are employed to engage with the ring member and the apical cuff to exert direct or axial compression of the ring member to the apical cuff and to the left ventricular apical tissue. A first variant includes an axial compression ring and a plurality of openings to accommodate the tissue anchors. A second variant includes a segmented axial compression ring composed of a plurality of arcuate members, which may be contiguous or joined to each other or not. Each of the plurality of arcuate members has at least one tissue anchor opening passing there through.

  • Publication number: 20240016495
    Abstract: An assembly and method for end-to-side connection to anatomical tissue is disclosed. The system and method are particularly useful in coupling a ventricular assist device pump to an aorta. The assembly and method include using a tubular graft member coupled to a connection ring having at least one of a plurality of distally projecting tines extending from a distal aspect of the connection ring, and a stent having a distal flange section configured to abut an abluminal wall surface of the aorta, and an assembly including the tubular graft member and connection ring, for delivering the end-to-side connection.
