  • Patent number: 9943300
    Abstract: A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes 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. First and second retainers are positionable external of the vessel and have a tip of a smaller transverse dimension and facing in a direction toward the covering member for advancement toward the covering member. A flexible connecting member operatively connects the covering member and the first retainer and moves the first retainer toward the covering member.

  • Patent number: 9226738
    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.
