TranQuill™ Sling Snoreplasty for Snoring and Mild Obstructive Sleep Apnea:

TranQuill™ Sling Snoreplasty for Snoring and Mild Obstructive Sleep Apnea: A Single-arm, Pilot Study for Safety and Effectiveness

The purpose of this study is to assess the safety and effectiveness of TranQuillTM Sling (a suture or thread used in surgery that is knotless) in snoreplasty (surgery procedure) for the treatment of snoring and mild OSA in adult subjects. The TranQuill Sling Snoreplasty (QSS) is a procedure where the suture will be inserted into the soft palate tissues for the treatment of snoring and/or mild obstructive sleep apnea. Soft palate tissues are tissues in the back of the roof of the mouth.

The research results will be used to provide data on feasibility (strengths and weaknesses), safety, performance, and effectiveness data for the Surgical Specialties, Inc as a therapy for snoring and/or mild obstructive sleep apnea. The TranQuillTM Sling is approved by the U.S. Food and Drug Administration (FDA). The TranQuillTM Sling is used in all types of surgery that involved deep tissues in the body.

The investigator in charge of the study is Dr. Boyd Gillespie. MUSC and Dr. Gillespie receive financial support from Surgical Specialties, Inc. to conduct the study. MUSC is the only place that this study will be conducted. For this research study the investigators plan to enroll a total of up to 20 subjects at the Medical University of South Carolina.

Study Methodology:

Subject Recruitment. Twenty subjects will be recruited from the MUSC Snoring Clinics as well as public information seminars held in the greater Charleston area. Attempts will be made to recruit both a gender and racially diverse study population.

Subject Screening. Subjects who are potentially eligible for the trial include patients who seek treatment chronic snoring disruptive to their bed-partner. Patients will require a pre-treatment assessment with a Watch-PAT home sleep study device to rule-out moderate and severe sleep apnea. Patients must have a regular bed-partner to participate in order to capture study outcomes.

Inclusion Criteria. Potential subjects must meet the following inclusion criteria:

• Age ≥ 22 years (no upper limit)
• Regular bed-partner
• Chronic, disruptive snoring according to bed-partner
• Snoring, upper airway resistance syndrome, or mild obstructive sleep apnea (AHI ≤ 15; lowest O2 saturation ≥ 85%) on home sleep testing with Watch-PAT
• No prior surgical treatment for snoring or OSAS other than nasal surgery
• Willing and capable of providing informed consent

Exclusion Criteria.

• Age < 22 years
• No regular bed-partner
• Intermittent or occasional snoring
• Moderate-to-severe obstructive sleep apnea (AHI ≥ 16; Lowest O2 sat <85%) or evidence of central apnea (≥ 10% of apneic events) on home sleep testing with Watch-PAT
