Gastric Stimulation
delivers electrical pulses to the stomach when a
person eats. The gastric stimulation pulse generator
is implanted through a minimally invasive
laparoscopic procedure and can be performed in an
outpatient setting. This implant results
in hunger control and ultimately could be an
effective method for weight loss.
Gastric
Stimulation Components
The system
includes a rechargeable ‘pacemaker-like' implantable
pulse generator (IPG) with an external, portable
charger; bipolar leads and external control and
monitoring components for the patient and physician.
The IPG is implanted under the skin and delivers
electrical stimulation to the muscle through leads
implanted in the sero-muscular layer of the stomach.
How the Gastric Stimulation
Works?
The Gastric Stimulation is
based on new technology called Gastric Contractility
Modulation (GCM) that is designed to sense naturally
occurring electrical activity of the stomach in
real-time and automatically apply electrical
stimulation treatment during meal times. The device
data can be non-invasively read by the physician for
further tailoring of the treatment parameters to the
patient. The result is enhanced gastric activity
without a change in the rate of electrical activity
(no pacing). The application of this unique
stimulation during initial stages of meals is
designed to provoke an early response of the gut
typical of a full meal.
Gastric Stimulator Induces
Weight Loss
Gastric
electrical stimulation can potentially improve
glucose control and induce weight loss in obese type
2 diabetic patients who are poorly controlled with
oral anti-diabetic medication, according to
preliminary study results reported at the European
Association for the Study of Diabetes in Rome.
Gastric stimulation is an alternative treatment to
gastric bypass
surgery and
lap band
surgery.
The gastric
stimulation surgery requires implanting a device that induces stomach
contractility and consists of three pairs of bipolar
electrodes connected to an implantable pulse
generator. The device automatically detects food
intake and applies gastric contractility modulation
signals to the stomach to induce early satiety.
A patient
needs only 1 hour per week to recharge the
implantable
gastric
stimulator and its pulse generator battery using an
external charger and the sensing and stimulation
parameters can be adjusted per subject using an
external programmer
