1. A tissue connector assembly comprising a surgical fastener comprising two clips, each sized and shaped to attach tissues and hold the tissues together therein; wherein at least one of said two clips is a self-closing clip adapted to self-transition from a first shape to a second shape, the first and second shapes being different, and a bridge portion connecting said two clips and spacing said clips from one another;wherein said bridge portion is substantially straight;wherein each of said two clips has an open configuration and a closed configuration independent of an other of said two clips; andwherein each clip has a proximal end point and a distal end point and wherein the proximal end point is separated from the distal end point when said clip is in said open configuration and wherein the distance between said proximal end point and said distal end point is reduced when said clip is in said closed configuration. 2. The tissue connector assembly of claim 1, wherein said self-closing clip comprises shape memory material. 3. The tissue connector assembly of claim 1, further comprising a coil surrounding a substantial length of said self-closing clip. 4. The tissue connector of claim 1, wherein said closed configuration is an unbiased configuration. 5. The tissue connector assembly of claim 1, wherein said closed configuration is a loop. 6. The tissue connector assembly of claim 1, wherein said open configuration is a biased configuration, and further comprising a release mechanism having a first position to bias said self-closing clip in said open configuration. 7. The tissue connector assembly of claim 1, wherein said closed configuration is an unbiased configuration, and wherein said release mechanism has a second position to unbias said self-closing clip into said closed configuration. 8. The tissue connector assembly of claim 7, further comprising a coil surrounding a substantial length of said self-closing clip, where said coil is coupled at one point on said self-closing clip and releasably coupled via said release mechanism at a second point on said self-closing clip. 9. The surgical fastener of claim 8, wherein said first position provides for compressing said coil between said first point and second point to form said biased configuration. 10. The tissue connector assembly of claim 9, wherein said second position provides for releasably uncoupling said coil from said second point to form said unbiased configuration. 11. The tissue connector assembly of claim 1, wherein said surgical fastener has two ends including a first end and a second end, and further comprising two tissue piercing members including a first tissue piercing member releasably coupled to the first end and a second tissue piercing member releasably coupled to said second end. 12. The tissue connector assembly of claim 11, further comprising a release mechanism, and wherein said release mechanism activates said release of said two piercing members from said respective two ends. 13. The tissue connector assembly of claim 12, wherein said release mechanism activates the closing of said self-closing clip. 14. The tissue connector assembly of claim 11, further comprising two sutures, wherein said coupling of said first tissue piercing member to said first end includes one of said sutures, and wherein said coupling of said second tissue piercing member to said second end includes the other of said sutures. 15. The tissue connector assembly of claim 14, wherein said suture of said first coupling and said suture of said second coupling are between about 10 mm and about 300 mm in length. 16. A tissue connector assembly comprising: a surgical fastener comprising two clips sized and shaped to attach tissues and hold the tissues therein including at least one self-closing clip having an open configuration and a closed configuration, where said closed configuration is an unbiased configuration having a loop shape and said open configuration is a biased configuration having a shape differing from a shape of said closed configuration, and a bridge portion having a substantially straight portion connecting said two clips; anda release mechanism having a first position to bias said self-closing clip in said open configuration and a second position to unbias said self-closing clip into said closed configuration;further comprising a coil surrounding a substantial length of said self-closing clip, where said coil is coupled at one point on said self-closing clip and releasably coupled via said release mechanism at a second point on said self-closing clip. 17. The surgical fastener of claim 16, wherein said first position provides for compressing said coil between said first point and second point to form said biased configuration. 18. The tissue connector assembly of claim 17, wherein said second position provides for releasably uncoupling said coil from said second point to form said unbiased configuration. 19. Tissue connector apparatus comprising a surgical clip sized and shaped to attach tissues, first and second tissue piercing members each having first and second end portions, first and second couplings, and first and second flexible members, said surgical clip having first and second end portions, said first coupling being coupled to said first end portion of said surgical clip and said second coupling being coupled to said second end portion of said surgical clip, said first flexible member having a first end portion coupled to said first coupling and a second end portion secured to said second end portion of said first tissue piercing member, said second flexible member having a first end portion coupled to said second coupling and a second end portion secured to said second end portion of said second tissue piercing member, said surgical clip comprising an elongated member, a pair of coils surrounding at least a portion of said elongated member, said pair of coils being serially arranged and spaced from one another along said elongated member, said elongated member being shape memory material and having an unbiased shape, which includes a plurality of loops, and a biased shape, said elongated member tending to move toward said unbiased shape from said biased shape. 20. The tissue connector apparatus of claim 19 wherein said first coupling releasably couples said first end portion of said surgical clip to said first needle. 21. The tissue connector apparatus of claim 20 wherein said second coupling releasably couples said second end portion of said surgical clip to said second needle. 22. Tissue connector apparatus comprising an elongated member having a first loop shaped portion adapted to hold tissue therein, a second loop shaped portion adapted to hold tissue therein, and a bridge portion bridging said first and second loop shaped portions, each loop shaped portion having a free end and being deformable into a second deformed shape and self-tending to return from the second deformed shape towards the loop shape; further including a pair of coils, one of said coils surrounding at least a portion of one of said first loop shaped portion and the other of said coils surrounding at least a portion of said second loop shaped portion. 23. The tissue connector apparatus of claim 22 wherein each coil has an outer end and an inner end, and said elongated member has two enlarged end portions, further including a restraint coupled to said elongated member adjacent to each of said inner ends. 24. Tissue connector apparatus comprising an elongated member having a first loop shaped portion, a second loop shaped portion and a bridge portion bridging said first and second loop shaped portions, each loop shaped portion having a piercing element at one end and a portion that merges into said bridge shaped portion, each loop shaped portion being deformable into a second deformed shape and having the property of tending to return towards its loop shape by moving upon itself; further including a pair of coils, one of said coils surrounding at least a portion of one of said first loop shaped portion and the other of said coils surrounding at least a portion of said second loop shaped portion. 25. The tissue connector apparatus of claim 24 wherein each coil has an outer end and an inner end, and said elongated member has two enlarged end portions, further including a restraint coupled to said elongated member adjacent to each of said inner ends.
