Abstract
A Quincke tipped introducer needle contains two shafts with lumens, one recessed, both connected by a slit for housing a U- or V-shaped disc shunt. The recessed shaft minimizes the penetration size of the introducer needle for insertion into a narrow and nerve laden space adjacent to a degenerated intervertebral disc. The longitudinal slit connecting the two lumens allows passage of the distal portion of the U-shaped disc shunt through the introducer needle, to be delivered into the intervertebral disc. Pain emitting from the avascular disc is extremely difficult to treat due to lack of penetration or permeability of drug. The lumens of the introducer needle are also used to retain a peri-shunt injectable into the disc shunt for delivery into the painful disc. The peri-shunt injectable can be an analgesic, narcotic, anti-inflammatory drug, antibiotic, anticonvulsant, antidepressant, buffer agent or alkaline agent to alleviate pain. The peri-shunt injectable can also be a nerve toxin retained within the lumens to be loaded within the shunt for terminating transmission of pain signal emitting from the disc.
