Experimental: Subject with severe tinnitus
Subjects diagnosed with severe tinnitus for at least six months, and it has not responded to conventional management will have surgical implantation of the device Tinnitus Implant System.
Device: Tinnitus Implant System
Device will deliver stimulation below hearing thresholds continuously or intermittently.
- Number of subjects with treatment-related adverse events [ Time Frame: One year ]Measured by subjects meeting one or more of the following criteria: worsening bone conduction thresholds in any tested frequency (0.25, 0.5, 1, 1.5, 2, 3, or 4 kHz) from baseline by a clinically significant amount (>10 dB) or worsening in WRS from baseline by a clinically significant amount (>20%) or worsening in video head impulse test result from baseline or one or more serious AEs
- Number of subjects to experience significant improvement from implantation of the device [ Time Frame: Baseline, 3 weeks, 5 weeks, 7 weeks, 9 weeks, 10 weeks, 11 weeks, 12 weeks, 13 weeks, 14 weeks, 15 weeks, 52 weeks ]Measured by subjects meeting at least two of three measurements of tinnitus severity: Tinnitus Handicap Inventory (THI) improvement by greater than 7 points using a 25-item self-assessment questionnaire with possible answers of Yes (4 points), Sometimes (2 points), and No (0 points) or Tinnitus Functional Index (TFI) improvement by greater than 13 points using a 25-item self-report questionnaire on a scale of 0 to 10 with a maximum possible score of 250 or Tinnitus visual analog scale improvement by greater than 15 points using a self-reported scale consisting of a 10 cm line with verbal descriptors (word anchors) at each end to express the extremes of the symptom; 0 mm designates no pain and 100 mm designates the greatest imaginable severity of pain.
