Abstract:
Device for manufacturing a tubular fibre comprising a wall delimiting internal compartments isolated from one another and containing a biologically active medium, the device comprising:extrusion means for coextruding a solution of at least one polymer and the biologically active medium to cause formation of a tubular fibre having a wall made from the polymer solution and containing the biologically active medium; means for supplying the extrusion means with the polymer solution and with the biologically active medium; means for controlling simultaneous supply of polymer solution and biologically active medium to the extrusion means and for interrupting the supply of biologically active medium at time intervals so as to form within the fibre successive compartments containing the biologically active medium and separated by a partition section formed from the polymer solution; and means for causing partial solidification of the fibre as it leaves the extrusion means, the partial solidification being sufficient to prevent the fibre from breaking at the partition sections.
