Abstract
A device for manufacturing tubular fibre includes an extrusion head through which a polymer and a biologically active material flow. The biologically active material is encapsulated within compartments formed in the fibre. Partial solidification is caused by structure, such as a coagulation bath, adjacent the extrusion head. This prevents breakage of the fibre as it leaves the head.
