Apparatus for manufacturing synthetic vascular grafts by an electrostatic spinning process comprises a rotating mandrel (10), an array of capillary needles (11, 12, 13) arranged on a manifold (14) for directing polymer solution towards the mandrel (10) when electrostatically charged, and electrodes (18, 19) for influencing the electrostatic field experienced by the polymer solution. There are means for altering the electrostatic charge of the electrodes (18, 19). <IMAGE> |
