The patient programmer is an external device that is about the size of a cell phone or PDA, and is used by the patient to activate the Inspire system before they go to sleep. The patient places the programmer over the implanted IPG site, and uses push buttons on top of the programmer to: a.) turn the therapy ON or OFF, b.) temporarily suspend therapy, or c.) make adjustments to the stimulation amplitude (within limits set by the physician). The patient programmer also allows patients to check the status of the IPG battery. There are both visual and audio indicators that provide confirmation of IPG status (Therapy ON/OFF and Battery Status). The patient programmer will only communicate with the Inspire system IPG
An assembly of battery-powered devices intended to apply periodic electrical stimuli to the vagus nerve to help control seizures and/or to help treat psychiatric disorder symptoms (e.g., depression). The vagus nerve stimulation (VNS) is provided through an implantable pulse generator, typically placed in the anterior chest wall, and leads that run subcutaneously to where their electrodes are implanted around the left vagus nerve. The system may be programmed externally following implantation.
