  • Publication number: 20240108872
    Abstract: An implantable vascular access port has a main port body with one or more hollow internal chambers formed therein each with a floor at the base of the internal chamber. The port body has an outlet aperture formed in a sidewall there of the internal chamber. One or more parallel, lateral, or angled-access apertures, relative to the port floor and associated septa are located opposite the outlet aperture in the main port body in a sidewall there of (parallel or lateral or angled-access aperture or septum), with at least a one perpendicular-access aperture and septum located opposite the floor of the internal chamber(s). The port chamber in the area of the outlet aperture has an at least partially conical shape directionally aligned with the parallel or lateral or angled-access aperture and septum, with said outlet aperture in contiguity a reversible outlet tube or port body needle locking mechanism.

  • Publication number: 20210378680
    Abstract: A vascular plug comprises a superstructure expandable from a collapsed percutaneous insertion configuration to an expanded deployment or use configuration. The superstructure is comprised of both primary and secondary three-dimensional shapes allowing for the occlusion of a wide range of vessel sizes from small to large through a disproportionately small delivery catheter. The plug includes a shape memory element for the generation of radial force and the creation of the larger secondary three-dimensional twisting or helical superstructure as is needed for target vessel occlusion.

  • Patent number: 11065007
    Abstract: A vascular plug comprises a superstructure expandable from a collapsed percutaneous insertion configuration to an expanded deployment or use configuration. The superstructure incorporates a channel or passageway and a catheter extends through the channel or passageway from a proximal side at least to a distal side of the superstructure. The central channel allows for over-the wire plug delivery and a working aperture for secondary vascular interventions under flow arrest prior to final plug release. The plug includes spring-loaded mechanical elements or clotting-enhancement structure for closing the channel or passageway upon a withdrawal or removal of the catheter from the superstructure.
