Abstract

See full text

A method for supporting repair of soft tissue with biopolymer fibers. Biopolymer is dissolved in acid in a closed container made of materials inert to the acid and to the collagen to form a biopolymer solution. The solution is stirred, then centrifuged to degas it. The degassed solution is put into syringes on a holder. The number of syringes equals the number of fibers in the bundle. The syringes are mounted in a rotatable holder. Essentially equal quantities of degassed solution are extruded from the syringes to produce fibers, which are gathered and fed into a formation buffer bath. The fibers are kept taught after extrusion and dehydrated in a dehydrating solution in a dehydrating bath. The fibers are wound a collector to collect the bundle. The fibers are used to support repair of soft tissue.
