Medical device for high blood pressure

0

MOBILE, Ala. (WALA) – The numbers are staggering. According to the American Heart Association, nearly half of all adults in the United States have hypertension, or 116 million people.

Also known as high blood pressure, hypertension can lead to thickening of the walls of blood vessels and increase the risk of heart attack when combined with cholesterol, making it the leading contributor to cardiovascular disease and death. premature.

A medical device from Medtronic designed to fix it is showing promise in a new trial.

The Symplicity Spyral is designed to provide a minimally invasive alternative to medication to help treat high blood pressure in patients by using radio frequency waves to calm overactive nerves near the kidneys.

Medtronic has long had high hopes for this concept, having spent $800 million in 2010 to buy kidney denervation technology maker Ardian.

The first clinical trials in 2014 gave disappointing results. However, with some changes to the device, the new results would be better in a statement from Medtronic.

“The ON MED study demonstrated significant reductions in office blood pressure, the most commonly used measure in clinical practice. Additionally, we saw reductions in absolute blood pressure that were consistent with previous RDN studies,” said Dr. David Kandzari, head of the Piedmont Heart Institute and Cardiovascular Services and the study’s principal investigator.

The next question is whether the FDA will grant approval.
