What are Implantable Pain Pumps?
An implantable pain pump, also known as an intrathecal drug delivery system, is a small medical device placed under the skin to deliver pain medication directly to the spinal fluid. By targeting pain at its source, the pump allows for much smaller doses of medication compared to oral drugs—reducing systemic side effects and providing more consistent pain control for chronic conditions.
When Are Implantable Pain Pumps Recommended?
Your physician may recommend a pain pump if you have:
- Chronic pain that hasn’t improved with conservative treatments or oral medications
- Severe back, neck, or nerve pain from conditions such as failed back surgery syndrome or complex regional pain syndrome (CRPS)
- Cancer-related pain requiring continuous relief
- Intolerance to oral pain medications or their side effects
How Are the Pain Pumps Implanted?
The procedure is typically performed in two stages. First, a temporary trial delivers medication through an external pump to assess effectiveness. If successful, the permanent pump is surgically implanted under the skin of the abdomen, and a thin catheter is positioned near the spinal cord. The pump is then programmed to release precise doses of medication. The surgery usually takes one to two hours and is done under local or general anesthesia.
What to Expect During Recovery After Implantable Pain Pump Surgery
Mild soreness at the incision site is normal for a few days. Most patients can return to light activities within a week. The pump requires periodic refills of medication, done during office visits every few months.
What Are the Risks of Implantable Pain Pumps?
