ABSTRACT:
An apparatus for the production of a collagen tube to be used as a vascular prostheses or nerve suture, including a cylindrical tubular spinneret having a feed end for an aqueous solution of collagen gel and a discharge end and a coagulant tube concentrically disposed in the spinneret with all around circumferential clearance and terminating upstream of the discharge wherein a tube of aqueous acid collagen gel is extruded through the clearance around the coagulant tube. The coagulant tube has its inner wall contacted with a coagulating solution emerging therefrom before the tube of aqueous collagen gel reaches the discharge end of the cylindrical tubular spinneret. The discharge end of the tubular spinneret terminates in a bath of coagulating solution and a bed is disposed in the bath to receive the extruded collagen tube from the end of the tubular spinneret. The tubular spinneret is capable of being displaced with respect to the bath.
