Interventions
- DeviceEnterra Therapy System
The Enterra Therapy System is a gastric electrical stimulator system consisting of an implantable pulse generator (Enterra II Model 37800 neurostimulator); two implantable unipolar leads (Enterra Model 4351-35 intramuscular); and device programmer (N'Vision Clinician Programmer Model 8840 with Model 8870 Application Card). The programmable neurostimulator operates on a sealed battery and electronic circuitry to provide controlled electrical pulse stimulation through the implanted lead system. A clinician programmer is used to program the neurostimulator and adjust stimulation settings to programmable parameters and stimulation options.
