Implantable Morphine Pumps

Intrathecal pumps are used to administer medication straight into the spinal fluid of patients. Only a small amount of medication is needed since it is delivered directly to the pain receptors. As you may have guessed, an implantable morphine pump is an intrathecal pump which delivers morphine to the patient’s spinal fluid.

The entire arrangement consists only of a pump and a catheter. The pump is the small, battery-powered device which holds and administers the morphine. The catheter is a thin tube which is connected to the pump and inserted into the patient’s spine. Both devices are implanted just beneath the skin.

Using a small needle, the doctor will fill the pump with morphine. The pump will send the morphine through the catheter and into the spinal fluid.
