Intrathecal Pump Placement For Long-Term Treatment Of Chronic Pain - Clinical Hub, Nursing Hub


An Intrathecal pump
 An implantable infusion system may be indicated for patients who have tolerated an intrathecal trial and whose life expectancy and analgesic needs are greater than 3 months.

Medtronic's intrathecal drug delivery systems are composed of two implantable components: an infusion pump and an intraspinal catheter. The pump is placed abdominally in a subcutaneous pocket, while the catheter is inserted into the intrathecal space of the spine, tunneled under the skin and connected to the pump. Medication can be delivered at constant or variable flow rates. The pumps weigh approximatley 4 ounces and are approximately 3 inches in diameter and one inch thick. The primary differences between the pump models are the size of the reservoir and the presence of a side catheter access port. The most commonly implanted pump model holds a maximum of 18ml of medication. To avoid the need for frequent pump refills the medicine is concentrated so that the required amount of medication can be delivered in:
