The Enterra® Therapy difference

A different approach to managing gastropararesis

Enterra® Therapy is the first and only device designed to reduce the nausea and vomiting secondary to gastroparesis through gastric electrical stimulation (GES).

Implanted in over 15,000 patients, it is an advanced therapy option for gastroparesis patients in their journey to find relief. 

Gastric Electrical Stimulation: Potential Mechanism of Action

The exact mechanism of action of GES is unknown, but the AGA clinical practice update on the potential mechanism hypothesizes that Enterra Therapy may impact the afferent (sensory) and efferent (motor) pathways between the stomach and central nervous system, the cell types found in the circular muscle (ICC-CM), and myoneural connections–allowing for the alleviation of symptoms.1

How Enterra Therapy works

Enterra Therapy stimulates the nerves and smooth muscles of the stomach by delivering mild electrical pulses, thereby reducing nausea and vomiting secondary to gastroparesis.

Neurostimulator
Leads

Leads deliver mild, controlled electrical pulses to the antrum portion of the stomach muscle wall.

Programmer

The system is programmed to optimise therapy for the individual patient.

Unlike other surgical options, therapy with GES is reversible and preserves the patient’s innate anatomy. Using the external clinician programmer, therapy can be turned on or off at any time without surgery. The device can also be removed from the patient’s body.

Procedure overview

Electrodes are implanted in the stomach wall

Enterra Therapy implant procedure typically takes 1-2 hours in a minimally-invasive laparoscopic or robotic surgical procedure, where the leads are placed on the serosal surface of the stomach’s greater curvature.

Neurostimulator is implanted in subcutaneous abdominal pocket

The neurostimulator is placed in subcutaneous tissue, typically in the abdomen.

Patient recovery is typically 1-2 days

While some patients leave same-day, a 1-2 day hospital stay is typical.

Therapy is adjusted non-invasively

Post-procedure, Enterra Therapy can be adjusted for symptom control via a programmer in an outpatient clinic.

CE mark

Enterra Therapy received the Conformité Européene (CE) mark in March 2002 and is supported by the NICE guidelines.

IMPORTANT SAFETY INFORMATION

The Enterra Therapy System for gastric electrical stimulation (GES) is indicated for the treatment of chronic intractable (drug refractory) nausea and vomiting secondary to gastroparesis.
