A tissue closure device including a tissue eversion apparatus, and a first and a second, redundant closure element that are placed on the external surface of a tissue puncture wound to enhance the efficacy of closure. The first closure element and the second closure element are left resident on the external surface of or in proximity to the tissue puncture wound in order to provide redundancy of closure.

1. A closure device for closing an opening in a tissue, the closure device comprising: a tubular member having a proximal end and a distal end region, an exterior surface, and a lumen extending along an entire length of the tubular member;a tissue eversion apparatus configured to form an everted tissue region, the tissue eversion apparatus having a plurality of elongate tissue engaging members disposed within the lumen of the tubular member and deployable therefrom, in a deployed position the elongate tissue engaging members having ends thereof configured to engage the tissue surrounding the opening, and in the deployed position the elongate tissue engaging members curve away from center axes of each of the elongate tissue engaging members thereof in a manner that the ends thereof face away from each other, for approximating and everting edges of the tissue engaged by the elongate tissue engaging members;a first closure element operatively coupled to the tubular member and deliverable therefrom for closing the opening, the first closure element being held in place in the lumen of the tubular member by a retention structure; the first closure element being a cincture element having a first size and a second size that is smaller than the first size; the first size being configured to surround a portion of the everted tissue region around the opening; and the second size being configured to capture the portion of the everted tissue region and close the opening when the cincture element is transitioned from the first size towards the second size. 2. The closure device of claim 1, the first closure element being disposed within the lumen of the tubular member and being deployable therefrom. 3. The closure device of claim 1, the elongate tissue engaging members of the tissue eversion apparatus having a first configuration substantially parallel to an axis of the tubular member when disposed within the tubular member, and having a second configuration curving away from the axis of the tubular member when the elongate tissue engaging members are projected out of the lumen. 4. The closure device of claim 3, the tissue eversion apparatus being moveable relative to the tubular member along the axis of the tubular member, motion of the tissue eversion apparatus along the axis past the end of the distal end of the tubular member allowing the plurality of elongate tissue engaging members to attain the second configuration, andretraction of the tissue eversion apparatus into the distal end of the tubular member allowing the plurality of elongate tissue engaging members to attain the first configuration. 5. The closure device of claim 1, the elongate tissue engaging members having sharpened ends configured to penetrate a portion of the everted tissue region. 6. The tissue closure device of claim 1, further comprising a closure actuator coupled to the first closure element, the closure actuator adapted to distally advance the first closure element from a region proximal to the everted tissue region to a region surrounding the everted tissue region, and the closure actuator being further adapted to transition the first closure element from the first size to the second size. 7. The tissue closure device of claim 1, the cincture element being a loop of suture having at least one pre-tied slip-knot. 8. The tissue closure device of claim 1, the first closure element being constructed of a bioabsorbable material. 9. The closure device of claim 1, the retention structure substantially preventing the cincture element from malpositioning or prematurely contracting. 10. The closure device of claim 1, the retention structure comprising a semi-solid biocompatible material. 11. The closure device of claim 10, the semi-solid biocompatible material comprising a wax-like material. 12. A closure device for closing an opening in a tissue, the closure device comprising: a first tubular member having a proximal end and a distal end region, an exterior surface, and a lumen extending along an entire length of the tubular member;a tissue eversion apparatus configured to form an everted tissue region, the tissue eversion apparatus having a plurality of elongate tissue engaging members disposed within the lumen of the first tubular member and deployable therefrom, in a deployed position the elongate tissue engaging members having ends thereof configured to engage the tissue surrounding the opening, and in the deployed position the elongate tissue engaging members curve away from center axes of each of the elongate tissue engaging members thereof in a manner that the ends thereof face away from each other, for approximating and everting edges of the tissue engaged by the elongate tissue engaging members;a second tubular member having a proximal end and a distal end region, an exterior surface, and a lumen extending along an entire length of the tubular member;a first closure element operatively coupled to the second tubular member and deliverable therefrom for closing the opening, the first closure element comprising a cincture element held in place in the lumen of the second tubular member by a retention structure, the retention structure substantially preventing the cincture element from malpositioning or prematurely contracting. 13. The closure device of claim 12, the second tubular member being slidable over the first tubular member. 14. The closure device of claim 12, the first closure element being disposed within the lumen of the second tubular member and being deployable therefrom. 15. The closure device of claim 12, the elongate tissue engaging members having sharpened ends configured to penetrate an interior surface of the edges of the tissue to be closed to form the everted tissue region. 16. The tissue closure device of claim 12, the first closure element being a cincture element having a first size and a second size that is smaller than the first size; the first size being configured to surround a portion of the everted tissue region around the opening; andthe second size being configured to capture the portion of the everted tissue region and close the opening when the cincture element is transitioned from the first size towards the second size. 17. The tissue closure device of claim 16, further comprising a closure actuator coupled to the first closure element, the closure actuator adapted to distally advance the first closure element from a region proximal to the everted tissue region to a region surrounding the everted tissue region, and the closure actuator being further adapted to transition the first closure element from the first size to the second size. 18. The tissue closure device of claim 16, the cincture element being a loop of suture having at least one pre-tied slip-knot. 19. The tissue closure device of claim 18, the loop of suture including at least one dentate configured to maintain the cincture element in a closed position. 20. The tissue closure device of claim 16, the cincture element being formed from a shape memory material having an expanded delivery configuration and a contracted deployed configuration that resiliently closes the opening when the first closure element is deployed around the everted tissue region. 21. The tissue closure device of claim 12, further comprising a second closure element being selected from a group consisting of sealant plugs, adhesive glues, occlusive substances, extraluminal clips, RF energy, thermal energy, electrical induction, infrared light, ultrasonic vibration, microwave or laser irradiation, sutures, and combinations thereof. 22. The tissue closure device of claim 12, the first closure element being constructed of a bioabsorbable material. 23. The closure device of claim 12, the retention structure comprising a semi-solid biocompatible material. 24. The closure device of claim 23, the semi-solid biocompatible material comprising a wax-like material.
