Multicenter Study
Long-term follow-up of a novel implantable programmable infusion pump.
The Prometra® Programmable Pump System (Flowonix Medical, Inc., Mt. Olive, NJ, USA) is designed for continuous intrathecal administration of morphine sulfate to treat chronic intractable pain. As a follow-up to a previous report on acute six-month data, this study evaluated the efficacy of treatment at one year and the accuracy of drug delivery throughout the study (average of 2.5 years, range 0-3.6 years). ⋯ The Prometra pump demonstrated accurate drug delivery throughout the study and provides an effective and safe means for intrathecal administration of morphine sulfate for treatment of chronic intractable pain.

Deep brain stimulation (DBS) is an effective technique that has been utilized to treat advanced and medication-refractory movement and psychiatric disorders. In order to avoid implanted pulse generator (IPG) failure and consequent adverse symptoms, a better understanding of IPG battery longevity and management is necessary. ⋯ Future work will be needed to provide more reliable management of implanted device batteries; however, implementation of a clinical algorithm that accounts for both estimated battery life and for patient symptoms should improve the care of DBS patients.
