inVENT-visIOn Study

A Clinical Study of the Acclarent Tympanostomy Tube Delivery and Iontophoresis Systems In-Office

The objective of the study is to evaluate the safety and efficacy of the Acclarent Tympanostomy Tube Delivery System (TDS) for the placement of Tympanostomy Tube TT(s) under local anesthesia delivered by iontophoresis in an office/clinic setting.

Inclusion Criteria:

• Scheduled to undergo tympanostomy tube insertion
• At least 6 months old
• Behavioral capacity and cooperative temperament to undergo an awake procedure (based on physician judgement)
• No history of sensitivity or reaction to anesthesia chosen for the procedure

Exclusion Criteria:

• Pregnant or lactating females
• Significantly atrophic, bimeric, or completely atelectatic tympanic membrane
• Otitis externa
• Lacerations or abrasions to the external auditory canal or damaged or denuded skin in the auditory canal
• Cerumen impaction resulting in a significant amount of cleaning required to visualize the tympanic membrane
• Electrically sensitive subjects and subjects with electrically sensitive support systems (pacemakers, defibrillators, etc.)
• Anatomy that precludes sufficient visualization of and access to the tympanic membrane
• Anatomy that necessitates tympanostomy tube placement in the posterior half of the tympanic membrane
