UMD: Catheters designed for use within the spinal column (i.e., columna vertebralis), particularly to infuse anesthetic, analgesic, or steroid substances. These devices are typically large-bore silicone rubber catheters. Most spinal catheters are used for management of intractable pain or spasticity and in regional anesthesia for labor, delivery, and during some surgical procedures.
