A device for closing an aperture in a vessel wall comprising an elongated member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture. The elongated member has a dimension to prevent egress of fluid through the aperture. A material forms two curved legs having ends positionable external of the vessel. The legs curve in different directions and a retention portion is formed in the material to retain the legs during placement of the elongated member inside the vessel.

The device of claim 1, wherein the first end portion of the elongated member extending between the first and second surfaces is curved. 7. The device of claim 1, wherein the elongated member has a first longitudinally extending portion extending from the intermediate portion to the first end portion in a first direction and a second longitudinally extending portion extending from the intermediate portion to the second end portion in a second different direction, wherein a width at the intermediate portion is greater than a width at the first longitudinally extending portion to patch the internal opening, wherein combined lengths of the first and second longitudinally extending portions exceed a length of the intermediate portion. 8. The device of claim 7, wherein the elongated member has a width at the intermediate portion greater than a width at the second longitudinally extending portion to patch the internal opening. 9. The device of claim 1, wherein the first and second members have blunt tissue engaging surfaces facing toward and spaced from respective upper surface regions of the elongated member in the placement position, the blunt tissue engaging surfaces movable independent of the elongated member. 10. The device of claim 1, wherein the width of the first and second end portions are substantially equal. 11. The device of claim 1, wherein a first thickness at the first end portion of the elongated member is less than a second thickness at the intermediate portion. 12. The device of claim 1, wherein the elongated member pivots without changing shape from a longitudinal position retained by a wall of an introducer to the transverse position when exposed from the introducer. 13. The device of claim 1, wherein the first and second members are non-penetrating. 14. The device of claim 1, wherein the first and second members have a curved outer surface extending in a circular fashion. 15. The device of claim 1, wherein the first and second members are symmetrical. 16. The device of claim 1, wherein the device does not include structure interposed between the elongated member and the first member and does not include structure interposed between the second member and the elongated member. 17. The device of claim 1, further comprising an elongated connecting member for connecting the first member to the elongated member. 18. 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, 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; andfirst and second members positionable proximal of the elongated member, the first and second members having a proximal surface and a distal surface, the distal surfaces of the first and second members in the placement position spaced proximally of the first and second upper surface of the elongated member, the first and second members movable to a placement position proximal 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 first member is spaced above the first upper surface region of the elongated member and the second member is spaced above the second upper surface region of the elongated member. 19. The device of claim 18, wherein the elongated member has a first longitudinally extending portion extending from the intermediate portion to the first end portion in a first direction and a second longitudinally extending portion extending from the intermediate portion to the second end portion in a second different direction, wherein a width at the intermediate portion is greater than a width at the first longitudinally extending portion to patch the internal opening, wherein combined lengths of the first and second longitudinally extending portions exceed a length of the intermediate portion.
