I have implanted all systems and routinely do about 60% medtronic, 30% abbott, remainder grab bag.
Used to do a lot of Nevro and my results were not Senza-like, my facility couldn’t afford Senza 2 batteries and senza 1 was just so big patients didn’t like it. They don’t like abbot proclaim 7 either fwiw. Abbott has a 5 year warranty on their Proclaim XR; but that is really just a new logo on Proclaim 5 and the bold XR settings to make it last 5 years are clinically unlikely, to be nice about it. I’ve had more than a few burn out in less than 2 years. The back pain responder rate is not published in the SUNBURST study but I is in the package insert and was about 39% so I would not use this for back pain.
Medtronic Intellis has best in class full body MRI conditionality. Mri can be performed w fractured leads, IPG doesn’t have to be fully charged, and in general is most accepted by radiology centers. It is also the smallest IPG, and has a 9 year warranty because the novel battery technology has less than 5% fade at 9 years.
Abbott requires MRI mode but can’t enter if there are any contacts with high impedance.
Boston curiously made their latest and greatest wave writer system to have a weird introducer and not be MRI conditional. Silly.
The results from the DTM-SCS study with Medtronic has made DTM the first line therapy in my practice for a patient suitable for a rechargeable. 80% of patients had >50% back pain relief and 63% of patients had >80% back pain relief. Average back pain relief per VAS was 74% and leg pain 72%.
For those of you not familiar with DTM and the rational design of the waveform to target the neuro-glial interaction should do some reading (substantiated by basic science preclinical work with transcriptomics describing a phenotype change in

). There are some upcoming webinars going through this science and it is wildly different than any other explanation of SCS mechanism that I have seen from any company. It is also not a black box, any doctor can see their programming.
The next webinar is 4/28. If anyone needs the link to register it is here:
