Mumbai: Can a device control blood flow so that you lose weight?
The head of one of the most prestigious medical schools in the country, KEM Hospital in Parel, recently received a patent for such a concept from the US Patent Office. Dean Dr. Hemant Deshmukh, an interventional radiologist, thought of the device while repairing narrowed blood vessels around the small intestine, reports Malathy Iyer.
Cardiologists fixate narrowed vessels around the heart, and interventional radiologists are trained to similarly fixate vessels in other parts of the body, such as the brain, lungs, legs, and abdomen, to help prevent stroke and gangrene. “The self-expanding, anti-blood flow device that we developed is about an idea that is taking shape,” Dr. Deshmukh, who has performed thousands of interventional procedures. said.
“As interventional radiologists, we treat arteries and veins by opening or closing them depending on the situation,” he said. It is not known that plaque build-up affects not only the heart vessels, but even the vessels in the abdomen. When the superior mesenteric artery, which supplies blood to the small intestine, develops blockages, the patient begins to suffer from an “abdominal angina”.
“The patient develops this angina when he or she eats. As a result, they develop fear of food and avoid it, resulting in 10 to 20 kg weight loss, ”said Dr. Deshmukh. The medical literature mentions that some of these patients develop cibophobia, which is defined as a fear of food.
He worked with Dr. Krantikumar Rathod. “We felt we could narrow the mesenteric artery in pathologically obese people by inserting a stent-like device that would induce weight loss,” he said. The narrowed artery induces cibophobia, which in turn leads to weight loss.
Doctors applied for the patent in April 2016 and received it earlier this month. The device they developed has a diameter of 8 mm, is shaped like an hourglass and is 15 to 20 mm long. “We now need to develop the delivery system, prototype it, and plan animal testing,” he said. These steps must be followed prior to human studies.
A senior surgeon that TOI spoke to said deliberately narrowing an artery with a device could cause clots. “Since morbidly obese people usually have diabetes or high blood pressure, the introduction of such a device must be carefully considered,” said a bariatric surgeon who did not want to be identified. Another doctor said that an idea that sounds good on paper may not always work in practice. Dr. Deshmukh said the device cited in the patent document with the “obesity reduction goal” could be used as a bridge treatment before weighting morbidly obese patients -reducing bariatric surgery. “It will help you lose 10-20 kg in a matter of weeks and it can be removed afterwards,” he added. The team is also investigating its usefulness in treating heart disease.
