Intrathecal Pump Implant

The first step is administering local anesthetic in order to maximize patient comfort during the procedure. Next, a catheter is inserted through a needle or small incision into the intrathecal space. This catheter is connected to a temporary pump. It will be used for several days to determine if the system is helping the patient. If pain decreases during the trial period, a permanent system may be implanted.

The permanent intrathecal pump procedure is typically performed while the patient is under general anesthesia. The temporary catheter is removed and, through a needle or incision, a permanent catheter is implanted.

The permanent intrathecal pump is implanted under the skin, usually in the abdomen. Implanting the pump is done to increase the longevity of the pump. The catheter is then connected to the pump. The pump's battery may last three to five years, after which a new pump is implanted.

The amount of medication dispensed by the pump is programmed with an external unit. Regular visits to The Pain Center are needed to refill the pump. After surgery, patients may experience mild discomfort and swelling at the incision sites for several days. Over time, the catheter may move or become damaged from strenuous activity and require re-positioning or replacement.
