Getting a Replacement – Enterra™ Neurostimulator


The Enterra™ neurostimulator is powered by a battery sealed inside the device. Over time, the battery will become too weak to power the neurostimulator, and a replacement device will need to be fitted by your consultant.

Replacement Surgery

When the battery in your neurostimulator runs down, your doctor may obtain prior authorisation from your local NHS trust and approval for a replacement surgery, and a procedure may be scheduled. 

During the surgery, your doctor will remove the neurostimulator and implant a new one. Your implanted leads will also be checked to make sure they are working properly. If they are, the new neurostimulator will be connected to the leads that are already in place. If the leads are not working as they should be, they will be replaced too.

The Enterra™ Therapy system for gastric electrical stimulation is authorised for use in treatment of chronic intractable (drug refractory) nausea and vomiting secondary to gastroparesis of diabetic or idiopathic etiology. The effectiveness of this device for this use has not been demonstrated.
