Value and source scope
Device
Boston Scientific Spectra WaveWriter, WaveWriter Alpha and WaveWriter Alpha Prime SCS Systems: IPG, percutaneous and surgical leads, extensions, splitters, adaptors, anchors and external trial stimulator [1][2]
Manufacturer
Boston Scientific Corporation, Marlborough, Massachusetts [1]
Interface class
Epidural spinal cord stimulation leads with an implanted IPG [1]
Origin
Commercial FDA-approved device; PMA P030017, original approval April 27, 2004 [1]

Species studied
Human [1]
Regulatory status
P030017/S363: FDA record decision date 02/05/2024; the SSED text prints the notice date as February 5, 2023, which does not match the record, so both are listed. S357 added diabetic peripheral neuropathy on October 5, 2023 [1][2]
Function

Value and source scope
Human subjects
SOLIS: 212 enrolled at the September 14, 2022 snapshot; 115 randomized (64 SCS, 51 conventional medical management); pre-specified cohort of 60 activated subjects; 23 US sites [1]
Preclinical cohort
Unreported
Follow-up duration
Primary endpoint at 3 months after activation; study ongoing at the time of the SSED [1]
Indications
Chronic intractable pain of the trunk and/or limbs including failed back surgery syndrome, CRPS I and II, intractable low back and leg pain, diabetic peripheral neuropathy of the lower extremities, and chronic low back and leg pain without prior back surgery for the WaveWriter systems [1]
Trials and registries
SOLIS: prospective, multicenter, randomized controlled trial, SCS versus conventional medical management, 1:1 [1]
Primary outcomes
At 3 months post-activation: 87.5% responder rate (50% or greater pain relief with no opioid increase) for SCS versus 8.3% for conventional medical management, p < 0.0001 [1]
Key limitations
Interim analysis of 60 subjects; the SSED itself notes the uncontrolled design aspects. 116 adverse events reported, 25 serious, 6 study-related events from one patient with an epidural abscess [1]
