The kit of claim 11, wherein the implant is selected from a urethral support, a rectal support, and a vaginal prolapse support. 13. A method of forming or assembling a surgical implant, the method comprising providing portions of implant material, each portion comprising an aperture, contacting the portions of implant material with the apertures aligned, inserting a polymeric rivet material from a surface of either implant material, the polymeric rivet material extending into the apertures, and processing the polymeric rivet material to attach the implant materials. 14. A method of forming or assembling a surgical implant, the method comprising providing a support portion comprising a material selected from a synthetic mesh material, a synthetic film material, and a biologic material, and comprising a support portion aperture, providing an extension portion comprising a material selected from a synthetic mesh material, a synthetic film material, and a biologic material, and comprising an extension portion aperture, contacting the extension portion and the support portion with aligned extension portion aperture and support portion aperture, inserting a polymeric rivet material from a surface of either the extension portion or the support portion, the polymeric rivet material extending into the extension portion aperture and the support portion aperture, and processing the polymeric rivet material to attach the extension portion to the support portion, wherein the polymeric rivet comprises thermoplastic having a processing temperature in the range from 350 to 500 degrees Fahrenheit. 15. The method of claim 14, wherein the polymeric rivet material is a thermoplastic polymeric material, the method further comprising inserting the polymeric rivet material as heated flowable polymeric rivet material and allowing the inserted polymeric rivet material to solidify to attach extension portion to support portion. 16. The method of claim 15, further comprising using a mold to maintain contact between extension portion and support portion, wherein the mold defines a space for injecting flowable polymeric rivet material into interstices of the extension portion and the support portion. 17. An insert mold adapted to assemble materials of a medical implant, the mold comprising closeable surfaces sized to contain portions of implant material, each portion comprising an aperture, a surface comprising an injection port adapted to be aligned with the apertures, a gasket, wherein when the closeable surfaces are closed to contain the implant material with aligned apertures, the gasket partially defines a space that contains the aligned apertures. 18. An insert mold according to claim 17, comprising closeable surfaces sized to contain surgical implant material comprising and end portion and a support portion, the end portion comprising an end portion aperture and the support portion comprising a support portion aperture, a surface comprising an injection port adapted to be aligned with the end portion aperture and the support portion aperture, a gasket, wherein when the closeable surfaces are closed to contain the end portion and the support portion, with aligned apertures, the gasket partially defines a space that contains the aligned apertures. 19. The mold of claim 17, wherein the gasket has a hardness in the Shore A range. 20. Apparatus comprising, in combination, the insert mold of claim 17 and a microinjector, the microinjector: operating at a temperature in the range from 350 to 500 degrees Fahrenheit; producing a single injection volume of injected material in the range from about 0.001 cubic centimeters to about 0.1 cubic centimeters, and including an injection barrel having a diameter in the range from about 0.125 to 0.5 inches, and an injector nozzle having a diameter in the range from about 0.01 to about 0.10 inches. 21.
