  • Patent number: 8333727
    Abstract: An anastomotic connector comprising an endovascular component including a vascular conduit and a supply conduit and a cannula component. The vascular conduit has first and second ends that are configured to reside within a vascular structure. The supply conduit has proximal and distal ends, where the distal end fluidicly connects to the vascular conduit between the first and second ends. The cannula component, which also includes proximal and distal ends, is received by the supply conduit.

  • Patent number: 8308715
    Abstract: An apparatus and method for stabilizing a cannula to a vascular structure. The stabilizer includes a ring that circumferentially surrounds the cannula. Three or more struts extend distally from the ring and are outwardly-deflected by a first angle relative to a first axis that is parallel to a lengthwise central axis of the cannula. Each strut includes a contact pad that radially extends from the strut and is distally-deflected by a second angle relative to a second axis that is orthogonal to the first axis. Three or more arms extend proximally from the ring and each arm opposes one of the struts. The arms are inwardly-deflected by a third angle relative to the first axis. The stabilizer is configured to move relative to the cannula until the contact pads engage the vascular structure, causing the arms to engage and resist further movement of the stabilizer relative to the cannula.

  • Publication number: 20120245616
    Abstract: An angioplasty balloon including a non-deployable stent to prevent or reduce the potential for slippage of the inflated balloon with respect to the vessel wall being treated. The balloon includes a non-deployable stent that is adapted to be secured to the balloon or angioplasty balloon catheter. The stent has a proximal end, a distal end, and at least three radially-spaced struts, each, each strut connecting the proximal end to the distal end and having one or more bends that allow expansion of the strut to accommodate the inflation of the balloon. The stem is made or a material so that the stent collapses upon deflation of the balloon.

  • Publication number: 20120004496
    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.

  • Publication number: 20110196190
    Abstract: A cannula for insertion through a biologic tissue. The cannula includes a shaft having proximal and distal end portions with a lumen therebetween. The cannula further includes a tip having a proximal end portion, a distal tip end, and a lumen therebetween. The proximal end portion of the tip is secured to the distal end portion of the shaft so that the lumen of the tip is in fluid communication with the lumen of the shaft. The tip includes an opening that extends proximally relative to the distal tip end to permit the flow of fluid into the lumen of the tip even in the event that the distal tip end becomes obstructed.

  • Publication number: 20110190567
    Abstract: A transseptal cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly includes a flexible cannula body having proximal and distal portions with a lumen therebetween, a tip coupled to the distal portion of the flexible cannula body, and first and second anchors coupled to the tip. The anchors can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue when in the expanded state. The anchors resist movement of the cannula assembly along a lengthwise central axis of the flexible cannula body.
