Vascular hole closure device

摘要

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.

1. 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 comprising:
a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture; first and second retainers for retaining the covering member positionable external of the vessel and proximal of the covering member in a placement position, the first and second retainers being independently movable toward the covering member, the first and second retainers each having a body of a first transverse dimension and each having a distal tip with a second transverse dimension smaller than the first transverse dimension, the distal tip facing in a direction of the covering member for advancement toward the covering member; and a flexible connecting member operatively connecting the covering member and the first retainer, the flexible connecting member movable proximally to move the first retainer toward the covering member.
