ABSTRACT:
An apparatus for making a hollow elongated member having a plurality of apertures therein comprising: a first component for supporting a hollow elongated member in a predetermined position and orientation for formation of a plurality of apertures therein; and a second component for forming a plurality of apertures at a predetermined position and orientation and of a predetermmined dimension thereof in the hollow elongated member; the second component being guidably received within the first component for alignment therewith. Alternatively, the apparatus includes an insert comprising rod means for forming a plurality of apertures of a predetermined size; and means for forming and supporting the hollow bore of the elongated member. The rod means is positioned at a predetermined orientation with respect to the bore forming means so that the hollow elongated member receives a plurality of apertures therein at a predetermined position, orientation and dimension. This embodiment includes a molding assembly comprising means for forming and supporting a hollow elongated member by substantially completely surrounding the member; a plurality of apertures located in the forming means for guidably receiving the rod means therein to properly orient the insert within a forming means; and means for introducing a polymerizable liquid into the molding assembly so as to form the catheter by polymerization of the liquid therein.
