  • Patent number: 10478591
    Abstract: A stent graft delivery device that is pre-loaded with a single guide wire for both tracking the device within a main vessel as well as for cannulating one or more branch vessels is described. The delivery device comprises a delivery catheter having a prosthesis releasably secured thereto and a nose cone extending from the proximal end of the catheter. In a delivery configuration, a secondary catheter is coaxial with the guide wire and extends through at least a portion of the prosthesis lumen and is held within a channel formed in the nose cone. In a released configuration, secondary catheter and guide wire are retracted distally out of the channel formed in the sidewall of the nose cone dilator and can be manipulated for cannulating a branch vessel.

  • Patent number: 10433990
    Abstract: An introducer for an endoluminal prosthesis and a methods for delivering a prosthesis within a body vessel are described. The introducer comprises pusher catheter having a lumen extending therethrough, the lumen being in communication with an opening formed in the sidewall of the pusher. A sheath is disposed over the pusher catheter and also has an opening formed in its sidewall. The sheath is longitudinally movable relative to the pusher catheter between a prosthesis delivery position and a prosthesis deployment position. When the sheath is in the deployment position, the opening formed in the sidewall of the pusher catheter is at least partially longitudinally aligned with the opening formed in the sidewall of the sheath. A wire may extend though the opening in the sheath, the opening in the pusher, through the lumen of the pusher and through a fenestration in a prosthesis to cannulate a branch vessel.

  • Patent number: 10376398
    Abstract: A delivery device and methods for deploying an endovascular prosthesis within the common and internal iliac arteries are described. The device comprises a pusher catheter having a proximal end and a pusher extension extending proximally therefrom. A tubular prosthesis having a side branch is releasably coupled to the pusher extension. An extension dilator extends proximally from the proximal end of the pusher catheter, extends at least partially along an external surface of the main tubular body, into a distal end of the side branch and exits a proximal end of the tubular prosthesis. The extension dilator can be tracked over a guide wire which serves to both position the device within a vessel and also to facilitate cannulation of an internal iliac artery.

  • Patent number: 10363154
    Abstract: The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. A trigger wire is adapted to be coupled to at least one of the proximal apices to restrain a proximal end of the stent during delivery. In a first embodiment, a first proximal apex comprises a bore for receiving the trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. The trigger wire therefore is only coupled to selected ones of the proximal apices. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

  • Patent number: 10350395
    Abstract: A system for supporting or dilating a body vessel includes a balloon catheter with a shaft having a delivery lumen in communication with an interior of the balloon. The balloon includes holes formed in the outer wall of the balloon. Additional or daughter balloons are delivered through the delivery lumen into the cavity of the balloon and through the holes into engagement with the holes. The daughter balloons are inflatable to seal against the holes, and the main balloon is subsequently inflatable when sealed by the daughter balloons. The daughter balloons may be delivered to branch vessels to provide support in addition to the inflation of the main balloon. The system may include preloaded wires extending through the delivery lumen and through the holes, and the daughter balloons can be delivered over the wires to the desired location.

  • Patent number: 10350096
    Abstract: A system for deploying a stent-graft within a body vessel is provided. The system includes an expandable stent-graft having expandable stent rings attached thereto and a cannula extending through the stent-graft. The system includes a plurality of diameter reducing connectors extending around the circumference of the graft for reducing the diameter of the graft. The system further includes a plurality of trigger wires extending longitudinally along the perimeter of the graft. The trigger wires extend through the diameter reducing connectors to constrain the connectors for reducing the diameter of the stent-graft. The trigger wires are also releasably attached to the apices of a bare stent portion extending from the proximal end of the graft body. The trigger wires can be sequentially retracted to release the bare stent and the diameter reducing connectors to expand the stent-graft radially into engagement with the wall of the body vessel.
