  • Publication number: 20190388650
    Abstract: One embodiment is directed to a system for creating translumenal vascular access, comprising a dilator adaptor member having proximal and distal ends and defining a dilator adaptor lumen therethrough, wherein the dilator adaptor lumen is defined by an inner diameter profile sized to accommodate insertion of one or more portions of a guidewire, and wherein the dilator adaptor is further defined by an outer diameter profile sized to accommodate at least partial insertion of the proximal end of the dilator adaptor into a dilator member lumen formed through a dilator member, the dilator member being coupleable to an introducer catheter member through an introducer member lumen formed through the introducer member.

  • Publication number: 20190069924
    Abstract: One embodiment is directed to a device for forming a tract, comprising an anchor assembly wherein at least a distal tip of the flexible distal portion is configured to be placed within a lumen of a blood vessel through a first passage created across the wall with a sharpened member at a first angle relative to a lumen longitudinal axis defined by the lumen of the blood vessel in the region adjacent the first passage; and wherein upon applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly, the needle is operatively coupled to the anchor assembly such that it may be advanced across the wall of the blood vessel and into contact with a saddle-shaped needle receiving structure, thereby creating an expandable tract between overlapping tissue portions of the vessel wall.

  • Publication number: 20180243001
    Abstract: One embodiment is directed to a method for creating translumenal vascular access, comprising utilizing a dilator adaptor to assist with forming a substantially atraumatic geometric outer junction between a dilator member/introducer member assembly and a guidewire which may be somewhat undersized relative to a lumen formed through the dilator member, thereby creating a geometric fit gap which may be suboptimal from a tissue interfacing perspective. The dilator adaptor may be interposed between the guidewire and dilator member to assist in remedying this fit mismatch, and in generally providing a preferred outer instrument interface for insertion through a small defect in a vessel to gain access to a lumen defined through the vessel.

  • Publication number: 20180235587
    Abstract: A method may comprise creating a first passage across a wall with a sharpened member at a first angle relative to a lumen; advancing an anchor assembly through the first passage such that a distal portion of the anchor assembly is placed within the blood vessel; applying a force to the anchor assembly to position an adjacent portion of the blood vessel wall into a desired contact configuration relative to the anchor assembly; and while maintaining the desired contact configuration, advancing a needle through a portion of the anchor assembly and through a portion of the wall of the blood vessel to form an expandable tract between overlapping tissue portions of the vessel wall, wherein a portion of the anchor assembly comprises a saddle-shaped needle receiving structure configured to receive and support the needle after it has been advanced across the portion of the wall to create the expandable tract.
