Abstract
A method of forming a plurality of hollow fibers includes the step of providing an elongated flexible substantially continuous fiber and coating an outer surface of the fiber with a hollow fiber material. The hollow fiber material is cured or hardened. A gap is created between the outer surface of the support fiber and the inner surface of the coating layer defined thereon. The coated support fiber is cut into a plurality of fiber segments each having exposed ends. The support fiber segments are removed from the coating layer so as to provide a plurality of hollow fibers.
