The patch of claim 2, wherein the polymeric layer comprises a bioabsorbable polymer. 6. The patch of claim 5, wherein the bioabsorbable polymer is selected from the group consisting of oxidized regenerated cellulose, polydioxanone, poliglecaprone 25 (copolymer of glycolide and epsilon-caprolactone) and combinations thereof. 7. The patch of claim 2, wherein the polymeric layer is an adhesion barrier. 8. The tissue repair patch of claim 1, wherein the base member additionally comprises an adhesion barrier. 9. The patch of claim 8, wherein the adhesion barrier comprises a polymer selected from the group consisting of group consisting of oxidized regenerated cellulose, polydioxanone, poliglecaprone 25 (copolymer of glycolide and epsilon-caprolactone) and combinations thereof. 10. The patch of claim 8, wherein the adhesion barrier comprises a polymer selected from the group consisting of silicone, PTFE, and ePTFE. 11. The patch of claim 1, wherein the base member comprises a mesh. 12. The patch of claim 1, wherein the base member comprises a fabric. 13. The patch of claim 12 wherein the fabric is woven. 14. The patch of claim 12 wherein the fabric is nonwoven. 15. The patch of claim 1, wherein the base member comprises an expanded polymeric film. 16. The patch of claim 1, wherein the base member comprises a biocompatible, nondegradable polymer. 17. The patch of claim 16, wherein the nondegradable polymer is selected from the group consisting of polypropylene, polyester, nylon, and ultra high molecular weight polyethylene. 18. The patch of claim 1, wherein the base member comprises a bioabsorbable polymer. 19. The patch of claim 18, wherein the bioabsorbable polymer is selected from the group consisting of polylactides, polyglycolides, polydioxanones, polycaprolactones, copolymers of glycolides and trimethylene carbonate, and copolymers of lactides and trimethylene carbonate, and copolymers and blends thereof. 20. The patch of claim 1, wherein the base member comprises a biocompatible nondegradable polymer and a bioabsorbable polymer. 21. The patch of claim 1, wherein the opening is a slit. 22. The patch of claim 1 wherein the opening is circular. 23. The patch of claim 1, wherein the opening is slot shaped. 24. The tissue repair patch of claim 1, wherein the closure member comprises opposed closure flap members hingingly mounted about the opening. 25. The tissue repair patch of claim 24, wherein the closure flap members have free end sections separated from the base member by slots, such that each closure flap member may be engaged in the slot of an opposed flap member. 26. The tissue repair patch of claim 1, wherein the closure member comprises a patch having an outer periphery, wherein a section of the periphery is mounted to the top side of the base member about the opening. 27. The tissue repair patch of claim 1, wherein the closure member comprises a surgical suture mounted about the opening. 28. The tissue repair patch of claim 1, wherein the closure member comprises a patch having a top side and a bottom side with an engagement member extending from the bottom side, and wherein the base member has a mating engagement member mounted to the top side about the opening, such that the closure patch may be engaged and disengaged from the base member. 29. The tissue repair patch of claim 1, wherein the opening comprises a slit having opposed sides and the closure member comprises a surgical suture threaded about the slit adjacent to the sides. 30. The patch of claim 1, wherein the opening is centrally located. 31. The patch of claim 1, comprising at least two openings and closure members. 32. The patch of claim 1, wherein the locating structure additionally comprises a downwardly extending flange member. 33. The patch of claim 1, wherein the locating structure comprises a bioabsorbable polymer. 34. The patch of claim 33, wherein the bioabsorbable polymer is selected from the group consisting of oxidized regenerated cellulose, polydioxanone, poliglecaprone 25 (copolymer of glycolide and epsilon-caprolactone), polylactide, polyglycolide and copolymers and combinations thereof. 35. The patch of claim 1, wherein the locating structure is formed into the periphery of the base member. 36. The patch of claim 35, wherein the locating structure is a downwardly extending flange member. 37. A method of performing a body wall defect repair in an open surgical procedure, comprising the steps of: A. inserting a tissue repair patch on an inside layer of a body wall having a tissue defect, wherein the repair patch comprises:a single plane tissue repair patch comprising a substantially flat single plane base member having a top tissue-facing side and a bottom viscera-facing side and a periphery;a locating structure positioned adjacent to the periphery of the base member on the bottom viscera-facing side;an access opening located in said base member and extending through the base member from the top side to the bottom viscera-facing side such that the locating structure and bottom side are accessible through said opening; and,a closure member associated with said opening adapted to prevent tissue or viscera from moving through the opening, said closure member having a first position such that the access opening is covered and underlying tissue or viscera is prevented from moving through the access opening and a second position such that the access opening is uncovered wherein a surgical instrument can be inserted therethrough,wherein the base member is affixed to tissue from the bottom viscera-facing side;B. positioning the patch about the defect such that the top tissue-facing side of the base member is adjacent to the inside layer of the body wall, and moving the closure member to the second position such that the access opening is uncovered;C. inserting an end of a surgical fixation instrument through the access opening to access the bottom viscera-facing side of the base member and positioning the end adjacent to the locating structure, and fixating the base member to the inside layer of the body wall through the bottom viscera-facing side of the base member; and,D. manipulating the closure member to the first position to cover the opening, thereby preventing underlying tissue or viscera from moving through the access opening. 38.
