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:

  • an elongated blood flow blocking member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture to patch the internal opening, the elongated member having a dimension to prevent egress of blood through the aperture, the elongated member having an upper surface, a lower surface, an intermediate portion and first and second end portions at opposing ends of the longitudinal axis, the upper surface having a first upper surface region and a second upper surface region adjacent the first upper surface region, the elongated member composed of an absorbable material, the elongated member movable between a first position for delivery and a second transverse position for placement, in the placement position the upper surface of the elongated member is positioned adjacent the aperture, wherein the first end portion and the second end portion are aligned with the longitudinal axis in the first position and the second position; and

    first and second movable members positionable proximal of the elongated member, the first and second movable members movable independently of the elongated member, the first and second members in the placement position having a proximalmost surface further from the elongated member and a distal surface closer to the elongated member, the proximalmost surface of the first and second members having a curved surface facing proximally, the distal surfaces of the first and second members in the placement position spaced proximally of the first and second upper surface regions of the elongated member, the first and second members positionable external of the vessel, in the placement position the first and second members positioned alongside one another such that the distal surface of the first member is spaced above the first upper surface region of the elongated member and the distal surface of the second member is spaced above the second upper surface region of the elongated member, the first and second members positioned alongside one another so the distal surfaces are substantially a same distance from the elongated member.
