1. A braided tube formation apparatus for assisting in the manufacture of a braided tube, the apparatus comprising:
an at least one elongated core mandrel;
an at least one elongated, radially collapsible outer tube comprised of a plurality of separate and distinct circumferentially spaced apart outer tube portions, the at least one outer tube sized and configured for removably receiving the at least one elongated core mandrel therewithin, such that the at least one core mandrel is coaxially positionable at least partially within the at least one outer tube for temporarily preventing the at least one outer tube from radially collapsing; and
an outer surface of the at least one outer tube configured for the braided tube to be circumferentially formed thereon; and
whereby, during use of the apparatus, after the braided tube is circumferentially formed on the outer surface of the at least one outer tube, the at least one core mandrel is removed from within the at least one outer tube, thereby allowing the outer tube portions to radially move inwardly toward one another so that the braided tube may be disengaged from the at least one outer tube.
