Corrigendum: Intrathecal drug delivery: Advances and applications in the management of chronic pain patient

In the published article, there was an error in the figure and legend of Figure 9. In the incorrect figure, the two columns of recording are switched. The T= 15 sec image should be T = 240sec and the T=240 image should be T=15sec. The corrected figure is the same except the images switched to correct for the mislabeled timing. The figure legend is now as follows.FIGURE 9 Two-dimensional diffusion chamber with a catheter having 20 microports. Images taken at 15 s (top, left) and 240 s (bottom, left), following bolus delivery of 2.6 μL as a bolus at time 0. The image on the right of the T =15 sec image shows an enlargement of the high velocity stream exiting the catheter at two of the exit valves, with the characteristic mushroom head where dye laden solute encounters the local dye-free fluid phase. Note the even distribution of dye from proximal (pump) to distal over the 6-cm catheter distance (T.L. Yaksh)
