Abstract:
1. A process for producing a flow element, the process comprising: forming an anti-restriction member having an elongated body, a proximal end and a distal end; forming the elongated body of the anti-restriction member from at least two wires; sizing and adapting the anti-restriction member to enable at least a portion thereof to be disposed by way of the distal end of the anti-restriction member into a proximal end of a flexible spinal needle previously inserted within a subject to permit fluid flow through the flexible spinal needle and to resist occlusion of the fluid flow through the flexible spinal needle; securing the proximal end of the anti-restriction member to a flow element body having an internal flow path for conducting a fluid through the flexible spinal needle; sizing and adapting the elongated body of the anti-restriction member such that a terminal end of the at least two wires forms the distal end of the anti-restriction member; and sizing and adapting the terminal end of the at least two wires to extend freely to a location proximate to a distal end of the flexible spinal needle.
