Microfluidic extrusion

A method for producing a bundle of 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.

Indirect method of articular tissue repair

Methods and devices for the repair of a torn or injured ligament or tendon are provided. The methods include the use of multiple scaffolds, e.g., beads. The multiple scaffolds may be positioned along a suture or other device such that they are moveable with respect to one another or the injured tissue.
