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; anda 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. 2. The device of claim 1, wherein the covering member has a first opening, the first opening configured to restrict movement of the flexible connecting member. 3. The device of claim 1, further comprising a second flexible connecting member, the second flexible connecting member moving the second retainer toward the covering member. 4. The device of claim 3, wherein the first and second flexible connecting members are sutures, and the first and second retainers and the first and second flexible connecting members are composed of a resorbable material. 5. The device of claim 1, wherein the covering member is composed of a resorbable material. 6. The device of claim 1, wherein the first and second retainers are composed of a resorbable material. 7. The device of claim 1, wherein the first and second retainers in the placement position are positioned in a substantially side by side relationship such that inner side surfaces of the first and second retainers are closer than outer side surfaces, the inner and outer side surfaces extending between lower and upper surfaces of the retainers. 8. 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; andfirst and second retainers positionable external of the vessel and proximal of 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 and facing in a direction of the covering member for advancement toward the covering member; anda first flexible connecting member operatively connecting the covering member and the first retainer and a second flexible connecting member operatively connecting the covering member and the second retainer, the first flexible connecting member movable proximally to move the first retainer toward the covering member and the second flexible connecting member independently movable proximally to move the second retainer toward the covering member, the first and second flexible connecting members being independently movable. 9. The device of claim 8, wherein the covering member has a first opening and a second opening independent of the first opening, the first opening configured to restrict movement of the first flexible connecting member and the second opening configured to restrict movement of the second flexible connecting members. 10. The device of claim 9, wherein the covering member has a third opening communicating with the first opening and a fourth opening communicating with the second opening, the third opening having a larger cross-sectional dimension than the first opening to enable freer movement of the first flexible connecting member therethrough and the fourth opening having a larger cross-sectional dimension than the second opening to enable freer movement of the second flexible connecting member therethrough. 11. The device of claim 8, wherein the covering member is composed of a resorbable material and the first and second retainers are composed of a resorbable material. 12. The device of claim 8, wherein the first and second flexible connecting members are sutures, and the first and second retainers and the first and second sutures are composed of a resorbable material. 13. The device of claim 8, wherein the first and second retainers in a placement position are positioned in a substantially side by side relationship such that inner side surfaces of the first and second retainers are closer than outer side surfaces, the side surfaces extending between lower and upper surfaces of the first and second retainers. 14. 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; andfirst and second retainers positionable external of the vessel and proximal of the covering member in a placement position, 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 and facing in a direction of the covering member for advancement toward the covering member, the first and second retainers being independently movable toward the covering member; anda first flexible connecting member operatively connecting the covering member and the first retainer, the first flexible connecting member being fixedly secured to the first retainer at one end wherein the first flexible connecting member moves the first retainer toward the covering member as a second end of the first flexible connecting member is moved proximally, the first retainer remaining fixedly secured to the first flexible connecting member at the first end as it is moved toward the covering member. 15. The device of claim 14, further comprising a second flexible connecting member operatively connecting the covering member and the second retainer, the second flexible connecting member being fixedly secured to the second retainer at one end wherein the second flexible connecting member moves the second retainer toward the covering member as a second end of the second flexible connecting member is moved proximally, the second retainer remaining fixedly secured to the second flexible connecting member at the first end, and the first and second flexible connecting members being independently movable. 16. The device of claim 15, wherein the covering member has first and second holes of different sizes to receive the first and second flexible connecting members and has third and fourth holes, the first and third holes frictionally engage the respective first and second connecting members and the third and fourth holes are dimensioned for free unrestricted movement of the first and second flexible connecting members. 17. The device of claim 15, wherein the covering member, first and second flexible connecting members and first and second retainers are composed of resorbable material. 18.
