Wireless pressure sensors are being used to warn doctors that a blood vessel is liable to burst.
On Monday, the Michael E. DeBakey VA Medical Center announced that it had implanted the Endosure sensor in patients who were receiving stents to protect against aortic aneurysms.
The sensor, approved by the FDA last month, promises a more effective, cheaper and safer way to make sure the stents are working.
Aneurysms occur when a weakened area of an artery gives way, creating a bulge. This is most likely to happen in the abdominal aorta, just under the kidneys.
Abdominal aortic aneurysms are the third leading cause of sudden death in elderly U.S. men and the 13th leading cause of death in the United States.
