Intrathecal Drug Delivery Systems

Intrathecal Drug Delivery Systems (IDDS) are surgically placed devices that carry medications directly to the cerebrospinal fluid within the spinal canal. This results in pain relief achieved with lower doses and fewer side effects. While oral medications are absorbed through the circulatory system, IDDS allows medication to be delivered to the pain receptors near the spine, triggering relief with a fraction of the medication, compared to oral ingestion. The lower doses also help minimize uncomfortable side effects that the oral medications can have.

IDDS devices have two components: a pump and a catheter. The pump is filled with the medication and sends it to the spinal fluid. The amount of medication delivered can be regulated by controlling the concentration or varying the infusion rate. The pump is typically refilled every one to three months. Most pumps can be controlled externally, allowing for non-invasive dosage control.
