2 INTRODUCTION 2.1 About This Booklet This booklet was written for people who are considering or have received a Nevro® Senza® Bluetooth® Spinal Cord Stimulator (SCS) Trial System to help treat pain. Every person is unique, and your medical needs differ from those of others, even people with the same condition and the same SCS system. For this reason, always talk to your doctor if you have questions about your condition.
of what is going on. You may be given medication to help you relax and some numbing medicine for the insertion site. The lead is placed in your body during a minor procedure usually without an incision. Once the lead has been attached to the Trial Stimulator, the Trial Stimulator will either be placed in a pouch or wrapped in bandages to your back. Most patients are able to leave the hospital the same day, depending on physical condition, the procedure, and doctor’s preferences.
3 DEVICE DESCRIPTION The Senza Bluetooth Trial System works by delivering electrical energy from a stimulator to an area around the spine. The system is capable of delivering HF10® therapy, a therapy that does not produce tingling sensations called paresthesia. It is also capable of providing stimulation that produces paresthesia at some therapy settings. For SCS therapy, a patient will typically first go through a trial phase to evaluate the therapy to see if it is right for them. 3.
Battery Compartment Stimulation OFF Button 2 AAA Batteries • Leads: Leads are thin insulated wires that connect to the Trial Stimulator at one end and have small electrodes on the other end placed near the spine. A small amount of electrical energy from the device travels through the leads and to the electrodes near the spine.
