This application helps patients conveniently manage the programs prescribed by their physicians and uses Bluetooth® wireless technology to communicate between the implanted stimulator and the Patient Controller NR app. The Patient Controller NR app runs on Abbott recommended devices (as mentioned below) and is easy to use, while the wireless interface provides patients the convenience of managing prescribed stimulation settings from a familiar iOS device. Some of the key functions available for patients include: - Turn stimulation ON/OFF - Select stimulation programs for changing therapy needs - Adjust stimulation amplitude - Check device battery - Turn on MRI mode for MR Conditional systems - Activate and de-activate Surgery Mode In addition, NeuroSphere™ Virtual Clinic on the Patient Controller NR app enables users to connect with their clinicians for routine programming adjustments remotely.
