Abstract
Methods for installing a flexible spinal needle assembly and methods of delivering a fluid may include inserting a distal end of a flexible spinal needle assembly into a subject and, thereafter, disposing an anti-restriction member at least partially within an inner flow path of the flexible spinal needle to substantially prevent fluid occlusion caused by bending or kinking of the flexible spinal needle.
