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 cover the aperture to prevent egress of fluid through the aperture, the covering member having an upper surface having a width transverse to the longitudinal axis and a length exceeding the width; andfirst and second legs each having portions positionable external of the vessel, the legs positioned external of the covering member, the first leg curving outwardly from the upper surface to form a first loop portion and the second leg curving outwardly from the upper surface to form a second loop portion, the first and second loop portions positioned external to the internal region of the vessel wall to contact tissue, the first loop portion extending distally toward the covering member and then looping to extend proximally of the covering member and then transitioning to a third loop portion looping toward the covering member, and the second loop portion extending distally toward the covering member and then looping to extend proximally of the covering member and then transitioning to a fourth loop portion looping toward the covering member, wherein a distance between outermost edges of the first and second legs is less than the length of the covering member. 2. The device of claim 1, wherein the first and second legs are fabricated from a unitary material. 3. The device of claim 1, wherein the first and second legs are composed of shape memory metal material. 4. The device of claim 3, wherein the covering member is composed of a resorbable material. 5. The device of claim 1, wherein the first and second legs are fabricated from a material which separates at a first region to form the first and second legs and the material includes a connection region spaced distally from the first region to connect the first and second legs to the covering member. 6. The device of claim 5, wherein the first and second legs are fabricated of metal material and the covering member is fabricated of a polymeric material molded over the metal material. 7. The device of claim 1, wherein the covering member is composed of a resorbable material. 8. The device of claim 1, wherein the first and second loop portions are substantially symmetrical. 9. The device of claim 1, wherein the first and second legs have a connection portion extending through a slot in the covering member. 10. The device of claim 1, wherein the first and second legs are composed of shape memory material and delivered in a substantially straightened position and the covering member is composed of a resorbable material. 11. The device of claim 1, wherein the first and second legs are formed from a flat sheet of metal. 12. The device of claim 1, wherein the first and second legs are formed from a round wire. 13. The device of claim 1, wherein the first and second legs are formed from a tubing with slits to bow outwardly. 14. The device of claim 1, wherein the first and second legs are formed from annealed metal. 15. The device of claim 1, wherein the first and second legs curve outwardly upon application of an external force against a portion of the legs. 16. 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, the covering member having an upper surface having a width transverse to the longitudinal axis and a length exceeding the width; anda clip portion extending from the upper surface and having a proximal region, a distal region and first and second legs extending between the proximal and distal regions and having portions positionable external of the vessel, the first leg curving outwardly from the proximal region to form a first closed loop portion transitioning into the distal region, and the second leg curving outwardly from the proximal region to form a second closed loop portion transitioning into the distal region, the first and second legs each having an S-shaped region, the first and second loop portions positioned to contact tissue external to the internal region of the vessel wall and a distance between outermost edges of the first and second legs is less than the length of the covering member. 17. The device of claim 16, wherein the first and second legs transition into an elongated portion of the clip portion which connects to the covering member. 18. The device of 16, wherein the covering member is composed of resorbable material. 19. The device of 16, wherein the first and second looped portions are substantially symmetrical.
