Intrathecal pumps are small devices that are implanted under the skin to deliver medication directly into the fluid of the spinal column (cerebral spinal fluid). This method of drug delivery is often used to manage chronic pain caused by conditions such as neuropathic or cancer-related pain. By delivering medication directly to the spinal fluid, intrathecal pumps can provide more effective pain relief with fewer side effects than oral medication.

 The pump itself is about the size of a hockey puck and is implanted in the abdomen, flank, or axilla. A catheter is also inserted into the spinal cord and connected to the pump. Medication is stored in the pump and delivered through the catheter to the spinal cord. The dosage and timing of medication delivery can be adjusted by a healthcare provider to meet the individual patient's needs. Patients may need to undergo a trial period with a temporary intrathecal pump before a permanent device is implanted. It is important to discuss the potential risks and benefits of intrathecal pumps with a healthcare provider to determine if this treatment is right for you.
