An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may include, or have blended in, an additive
An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may include, or have blended in, an additive, such as an osteoinductive factor, for example biocompatible ceramics and glass.

1. An implant for the repair or regeneration of internal tissue of a living being, said implant comprised of multiple segments comprising a tissue conductive matrix, at least a portion of said tissue conductive matrix comprising a blend of soluble collagen and native insoluble collagen fibers, where
1. An implant for the repair or regeneration of internal tissue of a living being, said implant comprised of multiple segments comprising a tissue conductive matrix, at least a portion of said tissue conductive matrix comprising a blend of soluble collagen and native insoluble collagen fibers, wherein at least a portion of said implant is porous, and further wherein said porous implant has a pore size that is at least about 100 microns. 2. The implant of claim 1, further comprising an additive. 3. The implant of claim 1, wherein said segments are in the form of granules, chips, or combinations thereof. 4. The implant of claim 2, wherein said additive comprises at least one factor configured to induce bone regeneration and repair. 5. The implant of claim 1, wherein said matrix further comprises at least one drug or biologically active agent. 6. The implant of claim 1, wherein said matrix further comprises at least one polymer other than collagen. 7. The implant of claim 6, wherein said polymer is at least partially bio-resorbable. 8. The implant of claim 7, wherein said polymer comprises chitin, PGA/PLLA copolymers, hydrogel, Lactide/μ-caprolactone copolymers, PGA, PLA, or PCL. 9. The implant of claim 2, wherein said additive comprises at least one of a biocompatible ceramic and biocompatible glass. 10. The implant of claim 9, wherein said additive comprises a metal oxide. 11. The implant of claim 9, wherein said biocompatible glass comprises phosphate glass. 12. The implant of claim 9, wherein said at least one additive is in the form of particles, and further wherein said at least one additive is blended with said tissue conductive matrix. 13. An implant for the repair or regeneration of a defect in internal tissue of a living being, said implant comprising an osteoconductive matrix and at least one calcium salt blended into said matrix, wherein at least a portion of said matrix comprises a mixture of native insoluble collagen and soluble collagen, wherein at least a portion of said implant is porous, and wherein said implant is comprised of multiple segments configured to be implanted into a body of a living to fill a void, and wherein said pores are at least about 100 microns in size. 14. The implant of claim 13, wherein said segments are in the form of granules, chips, or combinations thereof. 15. The implant of claim 13, wherein said calcium salt is at least one of a calcium phosphate and a calcium sulfate. 16. The implant of claim 15, wherein said calcium phosphate is at least one of tricalcium phosphate, hydroxyapatite and monetite. 17. The implant of claim 13, wherein said matrix additionally comprises at least one additive. 18. The implant of claim 17, wherein said at least additive comprises at least one of biocompatible ceramic and biocompatible glass. 19. The implant of claim 17, wherein said additive is osteoinductive. 20. The implant of claim 17, wherein said additive comprises a metal oxide. 21. The implant of claim 17, wherein said at least one additive is dispersed throughout the implant. 22. A segmented implant kit comprising a segmented implant for the repair or regeneration of internal tissue of a living being and a delivery system, said segmented implant comprising an osteoconductive matrix comprising a blend of soluble collagen and native collagen fiber, wherein at least a portion of said segmented implant is porous, and further wherein said porous portion has a pore size that is at least about 100 microns, and wherein the delivery system comprises a housing body and an ejector, wherein the segmented implant is configured to be ejected from said housing body by actuation of said ejector, such that said segments flow out from an opening in said housing body. 23. The segmented implant kit of claim 22, wherein said segmented implant is in a form selected from the group consisting of granules, chips, and combinations thereof. 24. The segmented implant kit of claim 22, wherein said segmented implant further comprises an additive. 25. The segmented implant kit of claim 24, wherein said additive comprises at least one of: biocompatible ceramic, biocompatible glass, and combinations thereof. 26. The segmented implant kit of claim 24, wherein said additive is one of: particles blended with said osteoconductive matrix, or particles dispersed throughout the segmented implant. 27. The segmented implant kit of claim 22, wherein said housing body comprises a syringe, or cannula, and said ejector comprises a plunger.
