Device: Active Stimulation
The Galvani System will be implanted in eligible participants, and stimulation will be turned ON |
- Safety and tolerability of the Galvani system [ Time Frame: 12 weeks ]Incidence and relatedness of Adverse Events (AEs), which include clinically significant findings from Laboratory Safety Assessments (clinical chemistry and hematology), vital signs (blood pressure, heart rate, respiratory rate, and body temperature), and 12-Lead ECG
- Effect of stimulation on the change in pharmacodynamic and response biomarkers [ Time Frame: Day 1 to week 12 ]Changes from baseline (Day 1) in the levels of LPS-inducible cytokine/ chemokine release, in whole blood assay at different timepoints after start of stimulation
- To evaluate the usability of the external Galvani System devices and accessories [ Time Frame: 12 weeks ]Summarize feedback collected on questionnaires pertaining to the use of the external Galvani System devices
- To evaluate the participants' perception of therapy and sensation [ Time Frame: 12 weeks ]Summarize feedback collected on questionnaires
- Evaluate device performance [ Time Frame: 12 weeks ]Tabulation of device deficiencies
