Participant Flow

The study enrolled a total of 25 subjects at six investigational sites in Australia. The pre-market study enrolled the first subject on 20 September 2022 and the last subject on 09 December 2022. Completion of follow-up in the pre-market study occurred on 19 January 2023. One subject was withdrawn before IPG implantation without collection of baseline information. All other subjects were implanted and completed 2-week and 6-week visits.
