0993 A Senseless Sensing Lead: A Case Of Failed Sensing Lead In Hypoglossal Nerve Stimulator

Abstract Introduction The hypoglossal nerve stimulator (HGNS) is an implanted device used to treat moderate severe obstructive sleep apnea (OSA), offering alternative form of therapy continuous positive airway pressure. Currently, the Inspire® Upper Airway Stimulation (UAS) system only such approved by U.S. Food and Drug Administration (FDA). Report case(s) We present a case sensory lead malfunction in 54-year-old man with OSA who underwent HGNS implant 2018 three-incision method positioned 6th intercostal space. December 2022, patient presented right sided chest pain subjective fever at outside hospital. A CT performed was significant for trace pleural effusion concern penetration lead. Device interrogation our office showed increased impedances abnormal waveforms prompting discontinuation scheduling surgical revision. He denied any trauma, injury area had been doing well overall but did feel as if wasn’t syncing appropriately his breathing. In addition, most recent study on fairly high amplitude 3.6V persistent supine disease. During surgery, noted be its original placement site intact anchors sutures holding it place. After removed there discoloration deep protective covering suggesting potential failure related compromise device. Conclusion Since FDA approval 2014, over 20,000 devices have USA long-term data collection efficacy safety ongoing. Manufacturer User Facility Experience (MAUDE) publicly available database device-related adverse events reported FDA. At time this abstract, are 714 reports which 147 involve respiratory 95 these relate and/or commonly due sensor tip separation migration from body. This illustrated presentation presumed electrical leakage insulation breach. Support (if any)
