  • Publication number: 20230053963
    Abstract: A device for closing an aperture in a vessel wall including a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. The covering member has a proximal surface and a distal surface, the distal surface having a concave surface and the proximal surface having a raised surface, wherein four openings are positioned in the raised surface. First and second retainers are positionable external of the vessel and first and second connecting members advance the respective first and second retainers toward the covering member.

  • Publication number: 20220370054
    Abstract: A surgical delivery instrument for delivering a vascular hole closure device having a hole covering member. The delivery instrument comprises a housing, a plunger and an advancer movable within the housing, the advancer having a first portion and a distal portion hingedly connected to the first portion and forming a casing for supporting the hole covering member. Distal movement of the advancer pivots the casing from an angled position to a more linear position to change the orientation of the covering member from a transverse position to a more aligned position. The plunger is advanceable to advance the covering member into the vessel.
