Purpose:

This is a prospective, multi-center feasibility study of effectiveness and safety of the Senza System in subjects with chronic, intractable pain of the upper limbs and/or neck. Data at follow-up visits will be compared to Baseline data collected at the beginning of the study.


Study summary:

Study subjects will be identified from the pool of candidates for SCS therapy affiliated with, or referred to, the clinical sites. Subjects will participate in this investigational plan that includes entry criteria evaluation, Baseline assessments, trial stimulation phase, and post-trial assessment. Subjects with a successful Trial Phase will receive a permanent implant of an Implantable Pulse Generator (IPG) and leads, and undergo 12 months of stimulation delivery with assessments at 1, 3, 6, 9, and 12 months Post-Permanent Device Activation. Subjects who sign the informed consent will undergo evaluations to determine eligibility for the study based on the inclusion and exclusion criteria. Baseline assessments will also include measures for pain, disability, functioning, medication use, quality of life, depression and sleep. Implantation and use of the Senza System will follow the Nevro Physician's Manual and supporting Manuals. Subjects will undergo a Trial Phase lasting up to 14 days to determine his/her response to SCS therapy. Following the Trial Phase with external device stimulation, subjects will be assessed for their pain, and those who have a successful Trial Phase will be eligible to proceed to permanent implantation of a SCS system. Following permanent device implant, the IPG will be "activated" and thus, stimulation delivered on an ongoing basis for 12 months. At 1 month and 9 months following Post-Permanent Device Activation, assessments of pain and adverse events will be made. At 3, 6, and 12 months Post-Permanent Device Activation, subjects will be assessed for pain and adverse events as well as disability, functioning, medication use, quality of life, depression and sleep. Patient Global Impression of Change, Clinician Global Impression of Change and subject satisfaction will be recorded at 3 and 12 months Post-Permanent Device Activation.

Be an appropriate candidate for the surgical procedures required in this study based on the clinical judgment of the implanting physician 4. Be on stable pain medications, as determined by the Investigator, for at least 28 days prior to enrolling in this study and be willing to stay on those medications with no dose adjustments until activation of the permanently implanted SCS device 5. Be 18 years of age or older at the time of enrollment 6. Be willing and capable of giving informed consent 7. Be willing and able to comply with study-related requirements, procedures, and visits 8. Be capable of subjective evaluation, able to read and understand English-written questionnaires, and are able to read, understand and sign the written inform consent in English. 9. Have adequate cognitive ability to use a patient programmer and recharger as determined by the Investigator Exclusion Criteria: 1.
