  • Patent number: 10835366
    Abstract: An arterial anchor device and a venous anchor device operably coupled by graft material to form an anastomotic convector is provided. The arterial anchor device comprises a generally tubular main body including a distal end and a proximal end, the distal end defining a plurality of flanges integrally formed with the tubular main body and being movable from a first loaded position to a second expanded position. The venous anchor device includes a tubular main body having a metal frame structure and including a distal end and a proximal end, the distal end including a plurality of barbs thereon wherein said distal end has an outer diameter greater than the proximal end. The arterial anchor device and venous devices are fluidly connected by a graft to form an anastomotic connector.

  • Patent number: 9597443
    Abstract: An anastomotic connector comprises a generally tubular access port having a first end and a second end, a generally tubular main body portion having a first end and a second end, wherein the second end of the main body portion is positioned adjacent to the second end of the access port such that the main body portion and access port are in fluid communication, and an anchor member received, within the access port and having a plurality of fingers that are extendable from the first end thereof. The fingers of the anchor member are movable between a loaded position wherein the fingers are substantially parallel to a center axis of the access port and an expanded position wherein the fingers are substantially perpendicular to the center axis of the access port.
