The Model 3150 IPG is the next generation Implantable Pulse Generator (IPG). It contains electronics and a battery that are sealed inside a titanium case. The Model 3150 is smaller in size than the previous model (3028) and eliminates the need of an Inspire respiratory sensing lead by having a built-in sensing accelerometer in the Model 3150 generator itself. The IPG is implanted subcutaneously, below the clavicle in the upper chest, and connects to the Inspire stimulation lead. The Model 3150 introduces improved communication speed between the IPG and the external products along with enhanced security. The Inspire system stimulates the hypoglossal nerve, synchronous with the patient’s respiration cycle using closed loop sensing technology. The timed stimulation elicits a neuromuscular response from the base of the tongue thereby preventing upper airway collapse that causes airflow obstruction in many OSA patients. The Model 3150 IPG will also allow patients to safely undergo magnetic resonance imaging (MRI) under specified conditions.
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.
