Abstract
Introduction
Providing various waveforms and programming options can facilitate more customized delivery of analgesic neurostimulation to chronic pain patients implanted with a Spinal Cord Stimulation (SCS) device. However, technologies that offer such optimization capabilities are not accessible to long-term implanted patients using older devices, some of whom may experience loss or attenuation in therapeutic efficacy over time. These
patients therefore may elect to undergo a “conversion” to a different SCS system that possesses these capabilities to gain access to these new technologies. In this study, we assessed a cohort of previously-implanted patients who converted to a new SCS device capable of combination therapy (simultaneous or sequential delivery of multiple available waveforms), enhanced algorthimic-based stimulation field targeting, and
waveform auomation.
Methods/Materials
This is a real-world, retrospective study of patients who were previously implanted with an SCS system (commercially-available device) who went on to convert to a different device (Boston Scientific) capable of multiple modality stimulation and/or combination therapy via an applicable device adaptor and new implantable pulse generator (IPG). Pain relief and other associated outcomes using both the previously-implanted SCS system and the newly connected device IPG are being collected.
Results
Collection and analysis of data is still on-going. Preliminary results will be presented.
Discussion
When experiencing problems with SCS device longevity and/or loss of efficacy, some previosuly-implanted patients may be able to obtain better outcomes using more advanced neuromodulation systems that offer a range of waveforms and programming options to address their chronic pain.
Conclusions
This European-based study will seek to evaluate previously-implanted patients who are empowered with the ability to selectively use an assortment of different waveform programming options following IPG conversion.
