Summary
Sensing lead malfunction occurred in 2.1% of patients receiving upper airway stimulation (UAS) for obstructive sleep apnea. Lead tip separation was the most common issue, often requiring revision surgery.
Area of Science:
- Medical Devices
- Sleep Medicine
- Surgical Technology
Background:
- Upper airway stimulation (UAS) is an effective obstructive sleep apnea treatment.
- The UAS device relies on a sensing lead for proper function.
- Sensing lead malfunction can compromise treatment efficacy.
Purpose of the Study:
- To determine the incidence of sensing lead malfunction in UAS patients.
- To analyze adverse event reports related to UAS sensing leads.
- To identify common causes and management strategies for lead failure.
Main Methods:
- Retrospective review of 190 UAS patients (July 2017-June 2022).
- Analysis of FDA MAUDE database for specific device models (Jan 2014-Sep 2022).
- Characterization of sensing lead malfunction types and revision surgery rates.
Main Results:
- Four patients (2.1%) experienced sensing lead malfunction.
- 122 MAUDE reports identified, with 72% requiring revision surgery.
- Sensing lead tip separation from the lead body was the most frequent issue (46% of reports).
Conclusions:
- Sensing lead integrity is crucial for UAS device function.
- Understanding lead failure modes is essential for optimal patient care.
- Waveform analysis can monitor sensing lead performance.

209
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...
