Real-World Efficacy of Evoke® Closed-loop Spinal Cord Stimulation (CL-SCS) Therapy in Chronic Pain Patients (ULTRA).

The Saluda Medical Evoke® CL-SCS System (Evoke System). The Evoke System measures and records spinal cord (SC) activation resulting from stimulation via evoked compound action potentials (ECAPs). The Evoke System can be programmed to provide ECAP-controlled, closed-loop SCS or open-loop, fixed-output (traditional) SCS; ECAPs may be measured and recorded in either stimulation mode.
