Figure 2. Modified intrathecal catheter system allows for sustained delivery of Evans Blue to the spinal cord.

Figure 2

The O’Buckley i.t. catheter system (A–C) is shown, along with side (B) and dorsal (C) views of catheter placement within the condylar canal. The O’Buckley i.t. catheter system successfully achieved sustained delivery of Evans Blue dye throughout the spinal cord (D). Images B–D were taken on Day 7 following catheter implantation. White arrows indicate the i.t. catheter insertion site, yellow arrows indicate the A-O membrane, and the blue arrow indicates the i.t. catheter underneath intact A-O membrane.
