Inspire Medical Systems, Inc. 3024 Inspire

The Model 3024 Inspire II IPG contains electronics and a battery that are sealed inside a titanium case. The IPG is implanted subcutaneously below the clavicle in the upper chest, and connects to the stimulation lead and sensing lead. The IPG has multiple programmable parameters that can be adjusted for a particular patient. Adjustments may be made to the sensing circuits to vary the timing of stimulation pulses and to the stimulation circuits to adjust the energy and duration of stimulation pulses. These adjustments provide the ability to optimize the opening of the upper airway. Based on typical settings from the STAR pivotal trial the longevity of the IPG’s battery will average 10 years. The Model 3024 IPG was originally developed by Medtronic and utilizes the same platform as Medtronic’s Itrel® 3 IPG which is FDA approved for other neurostimulation therapies.
