  • Publication number: 20230310187
    Abstract: Medical devices including vascular access kits and related system and methods are disclosed. In some embodiments, a vascular access system may include a first conduit, a second conduit, and an expandable stent that is coupled to both the first and second conduits such that there is a continuous lumen between the first conduit and the second conduit. Methods of deploying the vascular access system within the body of a mammal, more particularly, a human patient are disclosed. Methods of bypassing a section of vasculature of a mammal, more particularly, a human patient are disclosed. The vascular access system, when implanted and assembled, may be a fully subcutaneous surgical implant.

  • Patent number: 11554250
    Abstract: Medical appliances including reinforcing bands and radiopaque marker bands are disclosed. In some embodiments, bands may comprise two or more material layers. A first layer may control the mechanical properties of a multilayered marking band, and a second layer may exhibit greater radiopacity than the first layer. Bands may also comprise a single layer.

  • Patent number: 11383072
    Abstract: Medical devices including vascular access kits and methods of using the kit are disclosed. In some embodiments, a conduit is measured using an outside diameter measurement apparatus to determine if the conduit is compatible with a connector such that there is a continual lumen between the conduit and the connector. In some embodiments, various outside diameter measurement devices and the methods of their use are disclosed. In some embodiments, the methods of connecting a conduit, and in some embodiments a strain relief structure, to a connector are described.

  • Patent number: 11026704
    Abstract: Methods of declotting vascular access technologies, such as vascular access assemblies that facilitate hemodialysis, are provided. The methods can include disposing a catheter within a patient to access a vascular access assembly within the heart of the patient. The catheter can be coupled to the vascular access assembly such that a clot can be evacuated from within the vascular access assembly via the catheter.

  • Publication number: 20070167974
    Abstract: The present invention relates to a non-evertable blood filter that divides the transverse cross sectional area of a venous vessel into three annular regions or zones. The inner zone, the region immediately surrounding the longitudinal axis of the vessel, is maintained in a relatively open state with only minimal interference from the members making up the filter device so that blood flow can be maintained at a relatively normal rate. Concentrically surrounding the inner zone is the intermediate zone, to which captured emboli are directed out of the bloodstream passing primarily through the inner zone. Finally, concentrically surrounding the intermediate zone is the outer zone adjacent to the vessel wall.

  • Publication number: 20060190071
    Abstract: An endoprosthesis expansion system having, in combination, a delivery component such as a length of catheter tubing having at its distal end an intermediate sheath component, and an inner tube within the full length of the delivery catheter and intermediate sheath component. The inner tube has a protrusion affixed to its distal end, and an expandable endoprosthesis is fitted in a compacted state about the intermediate sheath, immediately proximal to the protrusion. If the endoprosthesis is a self-expanding endoprosthesis (as is preferred), an exterior constraining sheath is required around the outer surface of the endoprosthesis.
